When such costs become both probable and estimable, they are accrued as a component of supplemental rent through the remaining lease term. Changes to the assumptions utilized in the estimation of these lease return costs are accounted for on a cumulative catch-up basis.
These return provisions are evaluated at inception of the lease and throughout the lease terms and are accounted for as either fixed or variable lease payments (depending on the nature of the lease return condition). When such costs become both probable and estimable, they are accrued as a component of supplemental rent through the remaining lease term.

The $30 million decrease in fuel expense for the year ended December 31, 2023, compared to the corresponding period in 2022, was primarily driven by a 17% decrease in fuel prices, largely offset by the 17% increase in fuel gallons consumed during the year ended December 31, 2023, as a result of our 19% increase in capacity.
This 8% decrease in fuel expense for the year ended December 31, 2024 was primarily driven by the 12% decrease in fuel cost per gallon, partially offset by the 5% increase in fuel gallons consumed, as a result of our 5% capacity increase.
To the extent that there are material differences between these estimates and actual results, our financial condition and results of operations could be affected. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis.
