American Airlines expects to add more seats to some of its planes cutting down legroom for passengers.
The airline's vice president says the move is being made to match the number of seats with flight demand.
The added seats will likely be on the Boeing 737's and McDonnell Douglas M-D-80 jets.
American spokeswoman Stacey Frantz said that whatever the airline decides, it will still sell what it calls Main Cabin Extra seats. Those seats have more legroom and cost more than other seats in economy class.
