Allegiant Travel Company updated its first quarter 2026 outlook, now expecting a record quarter for total revenue despite system capacity being down about 5.5% year over year. Strong demand has outperformed earlier expectations.
Fuel costs have risen sharply, with expected first quarter fuel cost per gallon increasing to $3.00 from prior guidance of $2.60. Even so, Allegiant now projects an adjusted operating margin of 13.5% to 14.5% and adjusted earnings per share of $3.25 to $3.75, up from the previous range of $2.50 to $3.50. This guidance is on a stand-alone basis and excludes any contribution from the planned Sun Country acquisition.
Allegiant Travel Company reported that U.S. antitrust authorities granted early termination of the Hart-Scott-Rodino waiting period for its proposed acquisition of Sun Country Airlines.

The companies now expect the transaction to close in the second or third quarter of 2026, subject to remaining customary closing conditions. Allegiant and Sun Country describe the combination as creating a stronger leisure-focused airline with a broader network, more travel options and potential long-term value for shareholders.
