Travel revenue decreased $9.2 million from $48.0 million for the three months ended June 30, 2023 to $38.8 million for the three months ended June 30, 2024. The decrease in travel revenue is primarily driven by a 13% decrease in paid nights delivered as well as a 2% decrease in the ADR recognized for those paid nights resulting in decreases of $6.1 million and $1.2 million, respectively, to travel revenue. Travel revenue further declined by $1.6 million for deferrals from the Rewards program that did not exist during the three months ended June 30, 2023. Further declines in travel revenue were caused by net decreases in service fee revenue, cancel fee revenue, partner commission revenue and other travel revenue of $1.6 million and a decrease in contra revenue recognized for perks consumed for travel of $1.5 million. These decreases were partially offset by an increase of $3.0 million in revenue from IFG and IFB.
Subscription revenue decreased $10.8 million from $36.0 million for the three months ended June 30, 2023 to $25.2 million for the three months ended June 30, 2024. The decrease is primarily due to a 16% decrease in the number of subscriptions during the three months ended June 30, 2024 as compared to the three months ended June 30, 2023, resulting in a $5.9 million decrease to subscription revenue as well as a $3.8 million decrease from a decline in the revenue recognized per subscription due to the decline in Pass subscriptions. Additionally, subscription revenue further declined by $1.1 million for deferrals from the Rewards program that did not exist during the three months ended June 30, 2023.
Rewards and other revenue increased $3.3 million from less than $0.1 million for the three months ended June 30, 2023 to $3.3 million for the three months ended June 30, 2024. The increase is primarily the result of estimated usage related to Rewards, our member loyalty program, which was launched in August of 2023.
Cost of revenue. Cost of revenue decreased $13.5 million from $64.7 million for the three months ended June 30, 2023 to $51.2 million for the three months ended June 30, 2024, a decrease of 21%. The decrease is primarily a result of decreases in booking fees of $9.9 million driven by lower bookings, net decreases in lease costs of $3.5 million and a net decrease of $0.2 million from the transition of certain employees from cost of revenue to operations after June 30, 2023 partially offset by increases in employee costs remaining in cost of revenue.
Asset impairments. Asset impairments decreased $30.1 million from $30.1 million for the three months ended June 30, 2023 to $0.0 million for the three months ended June 30, 2024. During the three months ended June 30, 2023, we identified 33 leases for which the right-of-use assets and related property and equipment had net carrying values that exceeded their estimated fair value as determined by their estimated discounted future cash flows. Most of these leases were related to one group of underperforming properties in a single geographic location. Based on this information, we recorded right-of-use asset impairments of $30.1 million and property plant and equipment impairments of $0.3 million for the three months ended June 30, 2023. No asset impairments were identified for the three months ended June 30, 2024.
General and administrative. General and administrative expenses decreased $2.7 million from $16.7 million for the three months ended June 30, 2023 to $14.0 million for the three months ended June 30, 2024, a decrease of 16%. The decrease is primarily a result of a decrease of $1.8 million due to lower headcount from the reductions in force that took place during 2023, decreases of $0.6 million due to lower software license expenses, net decreases of $0.8 million from other expenses, including merchant processing fees and taxes and fees, partially offset by $0.5 million of higher legal and professional services fees.
Sales and marketing. Sales and marketing expenses increased $0.5 million from $8.3 million for the three months ended June 30, 2023 to $8.8 million for the three months ended June 30, 2024, an increase of 6%. The increase is primarily a result of higher employee compensation due to the transition of certain employees from operations to sales and marketing during 2023 as well as increases in employee costs between periods.
Operations. Operations expenses decreased $2.2 million from $7.0 million for the three months ended June 30, 2023 to $4.8 million for the three months ended June 30, 2024, a decrease of 32%, primarily due to a decrease of $1.3 million from the net transition of certain employees from cost of revenue into operations and from operations to sales and marketing and a net decrease of $0.8 million from lower spend due to decreases in the number of residences and other cost savings initiatives.
Technology and development. Technology and development expenses decreased $1.0 million from $3.3 million for the three months ended June 30, 2023 to $2.3 million for the three months ended June 30, 2024, a decrease of 31%, primarily due to the reductions in force that took place during 2023, which were weighted towards personnel within the technology and development department.
