Exhibit 10.1
                                                                 
                                                                 
                        FOURTH AMENDMENT
                         UAL CORPORATION
                  EMPLOYEE STOCK OWNERSHIP PLAN
                 (Effective as of July 12, 1994)


         By virtue and in exercise of the amending power reserved
to UAL Corporation (the "Company") under Section 13.1(a) of the
UAL Corporation Employee Stock Ownership Plan (effective as of
July 12, 1994) (the "Plan"), which amending power thereunder is
subject to the approval of the Air Line Pilots Association
International ("ALPA") and the International Association of
Machinists and Aerospace Workers (the "IAM"), the Company hereby
amends the Plan, subject to the approval of ALPA and the IAM, as
follows, effective as of August 1, 1996 (except as specified
below).
          
          1.  The following new paragraph is added immediately
following the third paragraph of the material labelled
"Transaction" which precedes Section 1:

          "The parties to the Recapitalization Agreement have
     recognized that the value of the Common Stock has increased
     significantly since the effective date of the Plan.  That
     increase is expected to result in an increase in the price
     at which the Trustee will acquire Class 1 Non-Voting
     Preferred Stock starting in 1996.  As a result of the
     significant price increase and limitations imposed under the
     Internal Revenue Code, the parties to the Recapitalization
     Agreement anticipate that the portion of the underlying
     shares of Preferred Stock which will be available under Part
     A may be reduced from 78.15% starting in 1996, as
     contemplated by Section 1.6(q) of the Recapitalization
     Agreement.  Any reduction in the Class 1 Non-Voting
     Preferred Stock under Part A for a Plan Year will be offset
     by a corresponding increase for that year in the shares of
     Preferred Stock under Part B and the Supplemental Plan."
           
          2.  The material labelled "Part A" which precedes
 Section 1 is amended by adding the following new paragraph to
 the end of such material:

          "For the Plan Years beginning on and after January 1,
     1996, the foregoing percentages will be adjusted as set
     forth in Section 5.4(a)(i)(A) to take into account the
     expected limitations on the amount of shares of Preferred
     Stock which can be delivered under Part A because of
     limitations under the Code.  It is expected that such Code
     limitations will result in an overall reduction of the
     number of shares of Preferred Stock which can be delivered
     in Part A. It is also expected that the total number of
     shares to be delivered in Part A to the Management and
     Salaried Employee Group will be unchanged, that the total
     number of shares to be delivered in Part A to the IAM
     Employee Group will be reduced, and that the total number of
     shares to be delivered in Part A to the ALPA Employee Group
     may be reduced.  The Company shall, pursuant to an agreement
     entered into pursuant to Section 1.6(q) of the
     Recapitalization Agreement among the Company and the unions
     representing the members of the ALPA and IAM Employee
     Groups, determine the number of shares which are expected to
     be delivered under Part A, determine the relevant
     percentages among the Employee Groups, and cause any
     reduction in the shares delivered under Part A to each
     Employee Group to be offset by a corresponding increase in
     the number of shares delivered under Part B and the
     Supplemental Plan to that Employee Group, so that the total
     number of shares delivered to each Employee Group will be
     unchanged."

          3.  Section 1(p) is amended by adding the following to
the end of the Section, it being understood that the language set
forth below is intended only as an explanation of the original
intent of the Plan and not as a substantive change to the Plan,
and is therefore effective July 12, 1994:
          
          "Compensation shall not include amounts paid in an
     employee contest or drawing of any type."

          4.  The following is added after the first sentence of
Section 3.1(a)(i):

          "For Plan Years 1996 through 1999 inclusive, the
     Company's contribution under Part A (and the corresponding
     principal payment due for the initial year of each
     Additional Acquisition Loan entered into for such years)
     shall be limited to the maximum contribution which the
     Company reasonably determines in consultation with its
     advisers can be made consistent with (w) satisfaction of the
     principles set forth in Section 1.6(l) of the
     Recapitalization Agreement, (x) achieving a high degree of
     certainty that the limits of Code Section 415(c)(6) shall
     not be exceeded, (y) avoiding an allocation which would be
     expected to cause all members of an Employee Group to exceed
     the limits of Code Section 415(c), and (z) limiting the
     release of shares of Class 1 Non-Voting Preferred Stock from
     the suspense accounts under the Acquisition Loans so that
     there are available for allocation that year sufficient
     shares of Class 2 Non-Voting Preferred Stock for each
     Employee Group to permit appropriate allocations in the
     Supplemental ESOP to individuals whose allocations reached
     the limit of Code Section 415(c).  The Company's
     contribution shall be determined under the Agreement
     Pursuant to Section 1.6(q) of the Recapitalization Agreement
     (the "1.6(q) Agreement") entered into by the Company, ALPA
     and the IAM, which provides that the amount of the
     contribution shall not be made by reconsidering the
     principles set forth in clauses (w) through (z), but shall
     instead be made by using the same methodology which was used
     by the Company (and verified by the Committee) for the
     determination of the Revised Class 1 Decimal under the
     1.6(q) Agreement, and that such methodology shall be applied
     by using such updated data as may be reasonably available to
     the Company prior to the determination of the contribution."
          
          5.  Section 5.4(a)(i)(A) is amended by adding the
 following to the end of the Section:

          "For Class 1 Non-Voting Preferred Stock released for
     Plan Years beginning on or after January 1, 1996 and before
     January 1, 2000, the allocation percentage shall be
     determined by the Company as described below.  There shall
     be determined the number of shares of Class 1 Non-Voting
     Preferred Stock available for allocation for the Plan Year,
     which is equal to the sum of (x) the number of shares of
     Class 1 Non-Voting Preferred Stock which will be released
     for the Plan Year on account of repayment of all Acquisition
     Loans and (y) the number of shares held in the suspense
     account referred to in Section 5.5(f) on account of excess
     contributions in the preceding Plan Year.  The number of
     shares of Class 1 Non-Voting Preferred Stock to be allocated
     for the Plan Year on behalf of dividends paid on previously-
     allocated shares shall be determined for each Employee
     Group.  The allocation percentage for the Management and
     Salaried Employee Group shall be the percentage which will
     result in a total allocation of 497,983.6564 shares of
     Class 1 Non-Voting Preferred Stock, including the shares to
     be allocated on account of dividends paid on previously-
     allocated shares.  The percentage to be allocated to the
     members of the IAM Employee Group shall be the least of (xx)
     the percentage which would result in a total allocation to
     the IAM Employee Group of 1,129,952.550 shares of Class 1
     Non-Voting Preferred Stock for such Plan Year, including
     shares to be allocated based upon dividends paid on
     previously-allocated shares, (yy) the percentage which is
     expected to result in the allocation of the sum of (i) the
     shares to be allocated based upon dividends paid on
     previously-allocated shares, plus (ii) the amount the
     Company reasonably determines, in consultation with its
     advisers, as the maximum allocation which can be made
     consistent with avoiding an allocation which would be
     expected to cause all members of the IAM Employee Group to
     exceed the limits described in Section 5.4(a)(iii), or (zz)
     the percentage which was contemplated for the allocation to
     the IAM Employee Group upon consummation of the Additional
     Acquisition Loan entered into during such Plan Year.  The
     allocation percentage to the ALPA Employee Group shall be
     one minus the sum of the allocation percentage to the
     Management and Salaried Employee Group and the IAM Employee
     Group."
          
          6.  Section 5.4(a)(iii) is amended by adding the
following to the end of the Section:
          
          "Effective for Plan Years beginning on or after January
     1, 1996, for purposes only of allocations of contributions
     under Part A, the amount of the limitation under Code
     Section 415(c) shall be reduced by an amount which is
     reasonably estimated by the Company for each Employee Group,
     as necessary to permit the allocation of Voting Preferred
     Stock under Section 5.4(c)(i), without violating the
     limitation of Code Section 415(c).  For this purpose, the
     amount of the reduction in the limitation may be estimated
     in any reasonable way, and such estimation may be made on a
     group-wide, rather than an individual basis; the amount of
     the reduction in the limitation need not be the same for
     each Employee Group."
          
          7.  Section 5.4(a)(viii) shall be redesignated as
clause (ix), the first word of such clause shall be changed from
"eighth" to "ninth", the reference "clauses (i) through (vii)"
shall be changed to a reference to "clauses (i) through (viii)",
and there shall be inserted a new clause (viii) as follows:

          "(viii) Eighth.  If the allocation of Employer
     contributions described in clause (vii) results in a
     violation of Code Section 415(c) for all members of any
     Employee Group (after reallocating any excess allocation
     owing to members of such Employee Group), then the excess
     allocation, and the shares released from repayment of
     Acquisition Loans resulting from such excess allocation,
     shall be placed in the suspense account referred to in
     Section 5.5(f), and the tentative allocations shall become
     final.  For this purpose, shares shall first be allocated in
     any Plan Year from the suspense account referred to in
     Section 5.5(f), and then from the shares released on account
     of repayment of Acquisition Loans, in the order the
     Acquisition loans were entered into."
          
          8.  Section 5.5(d) is amended by adding the following
 to the end of the Section:
          
          "For Plan Years beginning on or after January 1, 1996,
     Part B shall generally continue to be reduced before Part A,
     but Part A shall be reduced prior to Part B to the extent
     set forth in the provisions of Section 5.4(a)(iii) which
     refer to Voting Preferred Stock."

          9.  Section 5.5(f) is amended to read as follows:

          "(f) Excess Allocations.  If, after applying the
     allocation provisions under Section 5.4, allocations under
     Section 5.4 would otherwise result in a violation of Code
     Section 415, the ESOP Committee shall reduce Employer
     Contributions for the next limitation year for all
     Participants and shall hold excess amounts in a Suspense
     Account for allocation in a subsequent Plan Year in
     accordance with Reg. Section 1.415-6(b)(6)(iii).  The shares
     of Class 1 Non-Voting Preferred Stock which correspond to
     such excess contribution amounts shall also be held in such
     Suspense Account for allocation to Participants in a
     subsequent Plan Year.  If an amount is held in the Suspense
     Account referred to in this subsection (f) after the
     completion of allocations for any Plan Year, then such
     amount shall be allocated as part of the Employer
     Contribution for the immediately following Plan Year.  Such
     amount shall be included in calculating the allocation
     percentage among the Employee Groups, pursuant to Section
     5.4(a)(i).  Accordingly, in a Plan Year in which amounts
     held in the Suspense Account are allocated, the total
     Employer Contributions, including the amounts held in the
     Suspense Account, shall be allocated according to the
     allocation percentages established under Section 5.4(a)(i).
     The intended result of the allocation is that the Suspense
     Account should not alter the agreed-upon cumulative division
     of shares among the Employee Groups in Parts A and B and the
     Supplemental ESOP."
          
          10.  Section 7.2 is amended, effective as of the date
this amendment is adopted and approved, by adding the following
immediately before the words "provided, however":
     
          "or the Participant is determined to have a Total
     Disability"

          IN WITNESS WHEREOF, the Company has caused this Fourth
Amendment to be executed on July 16, 1996.
