Quarterly Financial Information Disclosure [Abstract]
Interim Financial Statements	NOTE 1. Interim Financial Statements Our accompanying unaudited consolidated financial statements of Hub Group, Inc. (“we”, “us” or “our”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements have been omitted pursuant to those rules and regulations. However, we believe that the disclosures contained herein are adequate to make the information presented not misleading. The financial statements reflect, in our opinion, all material adjustments (which include only normal recurring adjustments) necessary to fairly present our financial position as of September 30, 2017 and results of operations for the three and nine months ended September 30, 2017 and 2016. These unaudited consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016. Results of operations in interim periods are not necessarily indicative of results to be expected for a full year due partially to seasonality.

Acquisition

Business Combinations [Abstract]
Acquisition	NOTE 2. Acquisition Hub Group Trucking (HGT), a wholly owned subsidiary of Hub Group, Inc., acquired all of the outstanding equity interests of Estenson Logistics, LLC (“Estenson”) on July 1, 2017 (the “Estenson Acquisition”). Estenson is now our wholly owned subsidiary, operating under the name Hub Group Dedicated (“HGD”). As a result of the Estenson Acquisition, HGT acquired substantially all of the assets of Estenson, which include tractors and trailers, as well as assumed certain liabilities, including equipment debt. HGD is included in the Hub segment. HGD has an operating fleet of approximately 1,000 tractors and over 3,600 trailers. Dedicated services have been requested by our customers and we believe HGD is an excellent service offering that we can provide to our customers. The base purchase price for Estenson was approximately $285 million, including contingent consideration related to an earn-out provision included in the Purchase Agreement, which will not exceed $6 million and is based on Estenson’s EBITDA results through June 30, 2019. In accordance with the agreement, the base purchase price was adjusted by the assumed debt to arrive at the final consideration of $172 million. To facilitate the acquisition, we assumed $113 million of Estenson debt and paid $166 million in cash, including $55 million of cash, which was borrowed under our new line of credit (See Note 6). The following table summarizes the total purchase price allocated to the net assets acquired (in thousands): Cash paid $ 165,945 Consideration payable 1,366 Contingent consideration, fair value 4,703 Total consideration 172,014 Equipment debt assumed 112,677 Total base purchase price $ 284,691 Pending finalization of the fair market value of assets acquired and liabilities assumed, revenue and lease contracts, and deferred taxes related to tax valuation/tax goodwill the measurement period remains open. The following table summarizes the preliminary allocation of the total consideration to the assets acquired and liabilities assumed as of the date of the acquisition (in thousands): July 1, 2017 Cash and cash equivalents $ 12 Accounts receivable trade 27,000 Accounts receivable other 165 Prepaid expenses and other current assets 1,500 Property and equipment 128,477 Other intangibles 66,400 Goodwill 86,294 Other assets 64 Total assets acquired $ 309,912 Accounts payable trade $ 4,542 Accrued payroll 5,661 Accrued other 15,018 Equipment debt 112,677 Total liabilities assumed $ 137,898 Total consideration $ 172,014 The Estenson acquisition was accounted for as a purchase business combination in accordance with ASC 805 “Business Combinations.” Assets acquired and liabilities assumed were recorded in the accompanying consolidated balance sheet at their estimated fair values as of July 1, 2017 with the remaining unallocated purchase price recorded as goodwill. The goodwill recognized in the Estenson acquisition was primarily attributable to potential expansion and future development of the acquired business. The fair value assigned to the customer relationships identifiable intangible was determined using an income approach based on management’s estimates and assumptions. The fair value assigned to the property and equipment was determined based on a market approach. A probability weighted expected return model was used to estimate the value of the contingent consideration. Equipment debt was valued using a discounted cash flow analysis whereby future contractual principal repayments and interest payments for each instrument were discounted to the purchase date at a risk-adjusted discount rate. We incurred approximately $1.6 million of acquisition costs associated with this transaction prior to the closing date that are reflected in general and administrative expense in the Unaudited Consolidated Statements of Income for the nine months ended September 30, 2017. The components of “Other intangibles” listed in the above table as of the acquisition date are preliminarily estimated as follows (in thousands): Accumulated Balance at Estimated Useful Amount Amortization September 30, 2017 Life Customer relationships $ 66,000 $ 1,100 $ 64,900 15 years Trade name 400 400 - 3 months The above intangible assets are amortized using the straight-line method. Amortization expense related to this acquisition for both the three and nine month periods ended September 30, 2017 was $1.5 million. The intangible assets have a weighted average useful life of approximately 15 years. Amortization expense related to HGD for the next five years is as follows (in thousands): Remainder 2017 $ 1,100 2018 4,400 2019 4,400 2020 4,400 2021 4,400 The following unaudited pro forma consolidated results of operations for 2017 and 2016 assume that the acquisition of Estenson was completed as of January 1, 2016 (in thousands, except for per share amounts): Three Months Ended September 30, 2016 Revenue $ 988,345 Net income $ 20,249 Earnings per share Basic $ 0.61 Diluted $ 0.61 Nine Months Nine Months Ended Ended September 30, 2017 September 30, 2016 Revenue $ 2,986,342 $ 2,752,660 Net income $ 39,387 $ 62,212 Earnings per share Basic $ 1.19 $ 1.82 Diluted $ 1.18 $ 1.82 The unaudited pro forma consolidated results for the three and nine month periods were prepared using the acquisition method of accounting and are based on the historical financial information of Hub and HGD. The historical financial information has been adjusted to give effect to the pro forma adjustments that are: (i) directly attributable to the acquisition, (ii) factually supportable and (iii) expected to have a continuing impact on the combined results. The unaudited pro forma consolidated results are not necessarily indicative of what our consolidated results of operations actually would have been had we completed the acquisition on January 1, 2016.

Fair Value Measurement	NOTE 5 . Fair Value Measurement The carrying value of cash and cash equivalents, accounts receivable and accounts payable and long term debt approximated fair value as of September 30, 2017 and December 31, 2016 due to their short-term nature. We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less. As of September 30, 2017 and December 31, 2016, our cash and temporary investments were with high quality financial institutions in Demand Deposit Accounts (DDAs) and Savings Accounts. Restricted investments, as of September 30, 2017 of $24.1 million and December 31, 2016 of $20.9 million, included mutual funds which are reported at fair value. Our assets and liabilities measured at fair value are based on valuation techniques which consider prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. These valuation methods are based on either quoted market prices (Level 1) or inputs, other than quoted prices in active markets, that are observable either directly or indirectly (Level 2). Cash and cash equivalents, accounts receivable and accounts payable are defined as “Level 1”, while long term debt is defined as “Level 2” of the fair value hierarchy in the Fair Value Measurements and Disclosures Topic of the Codification.

As of September 30, 2017, our letters of credit were $13.5 million. On July 1, 2017, we entered into a $350 million unsecured credit agreement (the "Credit Agreement"). The Credit Agreement replaces the Amended and Restated Credit Agreement dated December 12, 2013 (“2013 Credit Agreement”). The Company used the Credit Agreement to finance, in part, the Estenson Acquisition. Our unused and available borrowings under our new Credit Agreement were $286.5 million as of September 30, 2017. Our unused and available borrowings under the 2013 Credit Agreement were $38.2 million as of December 31, 2016. We were in compliance with our debt covenants as of September 30, 2017. Borrowings under the Credit Agreement generally bear interest at a variable rate equal to (i) LIBOR plus a specified margin based upon the Borrowers' total net leverage ratio (as defined in the Credit Agreement) (the "Total Net Leverage Ratio"), or (ii) the base rate (which is the highest of (a) the administrative agent's prime rate, (b) the federal funds rate plus 0.50% or (c) the sum of 1% plus one-month LIBOR) plus a specified margin based upon the Total Net Leverage Ratio. The specified margin for Eurodollar loans varies from 100.0 to 200.0 basis points per annum. The specified margin for base rate loans varies from 0.0 to 100.0 basis points per annum. The Borrowers must also pay (1) a commitment fee ranging from 10.0 to 25.0 basis points per annum (based upon the Total Net Leverage Ratio) on the aggregate unused commitments and (2) a letter of credit fee ranging from 100.0 to 200.0 basis points per annum (based upon the Total Net Leverage Ratio) on the undrawn amount of letters of credit. The Credit Agreement contains various restrictions and covenants, including negative covenants that limit or restrict dividends, indebtedness of subsidiaries, mergers and fundamental changes, asset sales, acquisitions, liens and encumbrances, transactions with affiliates, changes in fiscal year and other matters customarily restricted in such agreements. The Company must maintain a Total Net Leverage Ratio of (a) total funded debt as of such date, minus up to $50,000,000 in unrestricted cash and cash equivalents (each as defined in the Credit Agreement) to (b) consolidated EBITDA (as defined in the credit agreement) of not more than 3.00 to 1.00; provided that as of the close of each of the four fiscal quarters occurring after the consummation of a permitted acquisition (as defined in the Credit Agreement) with an aggregate consideration of $150,000,000 or more, such ratio shall not be more than 3.25 to 1.00. The Company must maintain an interest coverage ratio of consolidated EBITDA to consolidated cash interest expense of not less than 3.00 to 1.00. We incurred $1.4 million of financing costs related to the Credit Agreement during the third quarter of 2017, which we capitalized and will amortize to interest expense over the term of the agreement. The unamortized balance of $1.3 million is included in Other assets in the Unaudited Consolidated Balance Sheet as of September 30, 2017.

Legal Matters	NOTE 8 . Legal Matters Robles On January 25, 2013, a complaint was filed in the U.S. District Court for the Eastern District of California (Sacramento Division) by Salvador Robles against our subsidiary, Comtrak Logistics, Inc., now known as Hub Group Trucking, Inc. Mr. Robles drove a truck for Hub Group Trucking in California, first as an independent contractor and then as an employee. The action was brought on behalf of a class comprised of present and former California-based truck drivers for Hub Group Trucking who were classified as independent contractors, from January 2009 to August 2014. The complaint alleges Hub Group Trucking has misclassified such drivers as independent contractors and that such drivers were employees. The complaint asserts various violations of the California Labor Code and claims that Hub Group Trucking has engaged in unfair competition practices. The complaint seeks, among other things, declaratory and injunctive relief, compensatory damages and attorney’s fees. In May 2013, the complaint was amended to add similar claims based on Mr. Robles’ status as an employed company driver. These additional claims are only on behalf of Mr. Robles and not a putative class. The Company believes that the California independent contractor truck drivers were properly classified as independent contractors at all times. Nevertheless, because lawsuits are expensive, time-consuming and could interrupt our business operations, Hub Group Trucking decided to make settlement offers to individual drivers with respect to the claims alleged in this lawsuit, without admitting liability. As of September 30, 2017, 93% of the California drivers have accepted the settlement offers which were paid in 2015 or earlier. In late 2014, Hub Group Trucking decided to convert its model from independent contractors to employee drivers in California. In early 2016, Hub Group Trucking closed its operations in Southern California. On April 3, 2015, the Robles case was transferred to the U.S. District Court for the Western District of Tennessee (Western Division) in Memphis. In May 2015, the plaintiffs in the Robles case filed a Second Amended Complaint (“SAC”) which names 334 current and former Hub Group Trucking drivers as “interested putative class members.” In addition to reasserting their existing claims, the SAC includes claims post-conversion, added two new plaintiffs and seeks a judicial declaration that the settlement agreements are unenforceable. In June 2015, Hub Group Trucking filed a motion to dismiss the SAC and on July 19, 2016, Hub Group Trucking’s motion to dismiss was granted in part, and denied in part, by the District Court. The motion to dismiss was granted for the claims of all purported class members who have signed settlement agreements and on plaintiffs’ claims based on quantum merit and it was denied with respect to federal preemption and choice of law. On August 11, 2016, Plaintiffs filed a motion to clarify whether the Court’s dismissal of the claims of all purported class members who signed settlement agreements was with or without prejudice and, if the dismissal was with prejudice, Plaintiffs moved the Court to revise and reconsider the order. Plaintiffs’ motion to clarify is fully briefed and the parties are awaiting a decision by the Court. Adame On August 5, 2015, the Plaintiffs’ law firm in the Robles case filed a lawsuit in state court in San Bernardino County, California on behalf of 63 named Plaintiffs against Hub Group Trucking and five Company employees. The lawsuit alleges claims similar to those being made in Robles and seeks monetary penalties under the Private Attorneys General Act. Of the 63 named Plaintiffs, at least 58 of them previously accepted the settlement offers referenced above. On October 29, 2015, Defendants filed a notice of removal to remove the case from state court in San Bernardino to federal court in the Central District of California. On November 19, 2015, Defendants filed a motion to transfer the case to federal court in Memphis, Tennessee and also filed a motion to dismiss the case pursuant to a clause in the independent contractor agreement stating that Tennessee law applies. Also on November 19, 2015, Plaintiffs filed a motion to remand the case back to state court, claiming that the federal court lacks jurisdiction over the case. The court granted Plaintiffs’ motion to remand to the state court in San Bernardino County on April 7, 2016, mooting Defendants’ motions to transfer and dismiss. On July 11, 2016, Defendants filed several motions in state court, asking the court to dismiss and/or stay the Plaintiffs’ suit for various reasons. During a hearing on October 5, 2016, the judge issued an oral tentative ruling stating that the choice of forum provision was unenforceable. On Defendants’ motion to dismiss the individual defendants, the court allowed for supplemental briefing for additional arguments regarding individual liability under PAGA. The court did not reach a decision regarding the motion to stay pending the outcome in Robles. Plaintiffs filed their supplemental brief on November 9, 2016 to which Defendants responded on December 6, 2016. On February 17, 2017, with the stipulation of the parties, the Court entered an Order dismissing, without prejudice, all of the individual Defendants and accepting the parties’ agreement that jurisdiction and venue are proper in the San Bernardino Superior Court and that Defendants will not seek to remove the case to federal district court. On April 12, 2017, the Court denied Defendants’ motion to dismiss based on insufficiency of the PAGA letter notice. On October 5, 2017, Plaintiffs served an amended complaint, in part dismissing the previously named individuals as Defendants. Lubinski On September 12, 2014, a complaint was filed in the U.S. District Court for the Northern District of Illinois (Eastern Division) by Christian Lubinski against Hub Group Trucking. The action was brought on behalf of a class comprised of present and former owner-operators providing delivery services in Illinois for Hub Group Trucking. The complaint alleged Hub Group Trucking misclassified such drivers as independent contractors and that such drivers were employees. The complaint also alleged that Hub Group Trucking made illegal deductions from the drivers’ pay and failed to properly compensate the drivers for all hours worked, reimburse business expenses, pay employment taxes, and provide workers’ compensation and other employment benefits. The complaint asserted various violations of the Illinois Wage Payment and Collections Act and claimed that Hub Group Trucking was unjustly enriched. The complaint sought, among other things, monetary damages for the relevant statutory period and attorneys’ fees. On October 24, 2014, the Lubinski case was transferred to the U.S. District Court for the Western District of Tennessee (Western Division), in Memphis. On September 22, 2015, the court granted Hub Group Trucking’s motion to dismiss Lubinski’s Illinois law claims with prejudice based on the contractual choice of law provision, which provided that Tennessee law governed. The court denied as moot Hub Group Trucking’s motion to dismiss based on federal preemption. On October 2, 2015, Lubinski appealed this order to the United States Court of Appeals for the Sixth Circuit in Cincinnati. On December 17, 2015, Lubinski filed his brief in support of his appeal of the motion to dismiss, asserting for the first time that the federal court did not have jurisdiction over the case due to a lack of diversity of citizenship. Hub Group Trucking filed its response brief on January 19, 2016, in part arguing that Lubinski had himself alleged diversity of citizenship in his complaint. Lubinski filed his reply brief on February 5, 2016. On April 1, 2016, the Sixth Circuit remanded the case to the district court—without ruling on the merits—for the district court “to consider the argument and admit the evidence necessary to determine the question of federal subject-matter jurisdiction.” On July 11, 2016, with his federal district court case still pending, Lubinski filed an additional putative class action Complaint, with the same claims, in Illinois state court. On the same day, Hub Group Trucking filed a declaratory judgment complaint in Tennessee state court, seeking a declaration that Lubinski’s claims must be heard in Tennessee (based on the contractual choice-of-forum provision) and that the claims must be dismissed because Tennessee law controls and Lubinski’s claims are preempted by federal law. On October 26, 2016, Lubinski filed a motion to dismiss for lack of federal subject-matter jurisdiction and a motion for leave to file an amended complaint, attempting to “clarify” the putative class definition and arguing that the Class Action Fairness Act’s exceptions to jurisdiction apply. In early 2017, Plaintiff’s counsel advised Hub Group Trucking that Lubinski would no longer challenge federal jurisdiction. On February 15, 2017, the District Court adopted the parties’ stipulation and found that there is federal subject-matter jurisdiction. On March 22, 2017, the U.S. Court of Appeals for the Sixth Circuit granted Plaintiff’s motion to recall the mandate and reinstate Lubinski’s appeal of the district court’s order dismissing the case. On June 8, 2017, the Sixth Circuit issued an Opinion affirming the District Court’s dismissal of Plantiff’s claims. On June 30, 2017, the Sixth Circuit issued the Mandate in the case, which terminates the 6 th We cannot reasonably estimate at this time the possible loss or range of loss, if any, that may arise from the remaining unresolved claims in the above mentioned lawsuits. We are a party to other litigation incident to our business, including claims for personal injury and/or property damage, bankruptcy preference claims, and claims regarding freight lost or damaged in transit, improperly shipped or improperly billed. Some of the lawsuits to which we are party are covered by insurance and are being defended by our insurance carriers. Some of the lawsuits are not covered by insurance and we defend those ourselves. We do not believe that the outcome of this litigation will have a materially adverse effect on our financial position or results of operations.

Accounting Changes And Error Corrections [Abstract]
New Pronouncements	NOTE 9. New Pronouncements In May 2014, the FASB issued Update No. 2014-09—Revenue from Contracts with Customers (Topic 606). This Standard provides guidance on how to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The FASB has recently issued several amendments to the standard, including clarification on the accounting for principal vs agent and identifying performance obligations. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). We currently anticipate adopting the standard using the full retrospective method to restate each prior reporting period presented, if material. We will elect to record sales tax on a net basis. We do not expect this election to have a material impact on our consolidated financial statements. Early application is permitted for annual reporting periods beginning after December 15, 2016. We plan to adopt this standard January 1, 2018, as required. While we are continuing to assess all potential impacts of the standard, other than additional disclosures, we do not anticipate that this standard will have a material impact on our consolidated financial statements. We have identified and analyzed our revenue streams and continue to analyze our current and historical contracts. In February 2016, the FASB issued ASU No. 2016-02, Leases, which requires lessees to recognize a right-to-use asset and a lease obligation for all leases. Lessees are permitted to make an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less. The new standard will become effective beginning with the first quarter of 2019. Early adoption of the standard is permitted. We plan to adopt this standard January 1, 2019, as required. We are currently evaluating the impacts the adoption of this accounting guidance will have on the consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting , In 2016, the FASB issued new guidance that requires credit losses on financial assets measured at amortized cost basis to be presented at the net amount expected to be collected, not based on incurred losses . In 2016, the FASB issued new guidance which clarifies the classification of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs, settlement of contingent consideration arising from a business combination, insurance settlement proceeds, and distributions from certain equity method investees. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements.
