DENVER (AP) -- Frontier Airlines says its flights will no longer be available on Expedia.
The Denver-based airline said Monday that a contract with the online travel agency expired this weekend, and it couldn't reach a new agreement to list its fares there. A spokeswoman didn't have details on the disagreement.
An Expedia representative didn't immediately return an email seeking comment.
Travelers can still find Frontier flights on other travel websites, but the airline says the best fares are on its own website, FlyFrontier.com.
Frontier is part of Republic Airways Holdings Inc. It has been encouraging travelers to book flights on its own website by offering those customers advance seat assignments, lower fees and more frequent-flier miles.
Frontier says it costs the airline up to $25 per booking when passengers book on other sites.
