NEW YORK -- Expedia has stopped selling tickets on American Airlines flights, the latest twist in a pricing dispute between American and travel websites.
"Expedia has chosen to no longer offer American Airlines fares on its website," American said in a statement. "Customers looking to compare flights or fares online should visit other travel sites such as Kayak.com or Priceline.com for the most accurate and up-to-date information."
The Fort Worth-based airline has said it would like to sell more tickets through its own website.
Airlines pay a commission every time people search a particular flight, look up a fare or book a trip.
Expedia's removal of American flights marks an escalation in a months-long dispute between the airline and various travel sites. Last month, American Airlines pulled its flights from travel website Orbitz, saying consumers could just as easily buy tickets from American's website.
Expedia recently made American flights harder to find on its website, an apparent response to the airline's decision to drop Orbitz. Expedia warned that it "cannot support efforts that we believe are fundamentally bad for travelers."
Experts cautioned that while American might save money in commission fees, its sales will drop if its flights don't appear on sites such as Orbitz and Expedia.
About a third of Americans book their tickets on such travel sites.
Analysts say that only smaller airlines such as Southwest Airlines Co. can get away with selling tickets exclusively on their own websites.
Expedia, based in Bellevue, Wash., did not immediately respond to a message seeking comment Saturday.
