You Can Now Book Allegiant Flights on Expedia

Expedia Group is now the first authorized online travel agency ever allowed to sell Allegiant flights. The 12-month exclusive agreement puts Allegiant's 566 nonstop routes across 124 U.S. cities onto every Expedia Group brand in the U.S.

Allegiant was the last OTA holdout, selling seats only through its own site and call center until this announcement. Because the deal is exclusive for a year, Priceline, Kayak and everyone else stay shut out until at least July 2027.

Andrew's Take

The OTA holdouts are folding, and it isn't a coincidence. Southwest spent two decades selling only on southwest.com, then went to Expedia in February 2025. Now Allegiant, the last one standing, has folded too. Direct-only was a bet that the extra traffic wasn't worth the commission — and one by one, the airlines are realizing they were wrong.
