FORT WORTH, Texas - American Airlines says it will use Frontier's parent company, Republic Airways Holdings Inc., to operate regional flights using 76-seat planes.
American said Thursday that it reached a 12-year deal with Republic. The agreement is subject to approval by American's federal bankruptcy court judge.
The move represents a break from American's sister carrier, American Eagle. Both are owned by AMR Corp., which filed for bankruptcy protection in 2011.
Under the agreement, Republic Airlines will get 53 Embraer planes painted in American Eagle colors. They will go into operation at a rate of two or three per month starting in mid-2013.
American says the deal will help it match the right size plane to market demand on certain routes and diversify its roster of regional carriers.
Republic owns Frontier Airlines, Chautauqua Airlines, Republic Airlines and Shuttle America.
