American Airlines is halting charter operations for six NFL teams during the 2017-2018 season.
The airline says it needs the aircraft to maintain scheduled services, according to an internal memo seen by Forbes.
"Network planning has advised we will have fewer aircraft available for charter flying in 2017 and after careful analysis it is necessary to reduce the number of NFL teams we carry this season," the memo said.
It will end agreements to transport the Arizona Cardinals, the Baltimore Ravens, the Indianapolis Colts, the Jacksonville Jaguars, the Miami Dolphins and the Pittsburgh Steelers to games.
"This was a very tough decision as many of the teams have been longstanding customers of the airline," American said.
It will however continue to fly hometown team the Dallas Cowboys, the Carolina Panthers and the Philadelphia Eagles.
"After careful evaluation, we are reducing the number of charter operations for 2017 to ensure we have the right aircraft available for our passenger operation," said American spokeswoman Lakeesha Brown.
