Frontier Airlines Feb. 25 pulled its flights from Expedia, saying in a statement that it was unable to reach an agreement with the online travel agency.
The carrier in the statement encouraged travelers to book through its website, flyfrontier.com, where it said its "best fares continue to be found." Travelers are guaranteed seat assignments and will earn more Early Return miles when they book on its website, Frontier said.
"Customers can still find our low fares on other travel sites such as Travelocity, Orbitz and Priceline, but will get the best value with Frontier when they book directly at FlyFrontier.com," said Daniel Shurz, Frontier's senior vice president, commercial.
Travel agents can book Frontier in GDSs and can book advance seat assignments for tickets that are "D" class and higher. For tickets that are "M" class and lower, agents must call the airline in order to get a seat assignment.
Expedia said that its contract with Frontier is "in negotiation" after the recent expiration of the contract between the airline and Expedia.
"In the meantime, we have elected to pull Frontier flights and fares from select Expedia-brand and Hotwire sites," Expedia said in a statement. It added, "We value our relationship with Frontier, and we look forward to offering their full content on our Expedia and Hotwire sites."
