Frontier Airlines, a unit of Indianapolis-based Republic Airways Holdings Inc., said Monday that 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. Expedia says it has removed Frontier flights from select Expedia-brand and Hotwire sites as it negotiates a new contract. The companies didn't disclose details of the negotiations.
Travelers can still find Frontier flights on other websites, but the airline says the best fares are on its own website, FlyFrontier.com.
Frontier 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.
Republic shares were down 10 cents Tuesday morning, to $9.50 per share.
