The 'operating carrier' is the airline that flies the plane.

It determines where you check in and board, so it's important you know who operates your flight before you travel!
You can find who's operating your flight next to the flight number:

  • When you book
  • On the confirmation page
  • In your confirmation email


The 'marketing carrier' is the partner airline that sells seats on the operating carrier's flights.
While we work to make our airlines (and websites) one, you can buy flights on both airlines on both sites.

Be sure to see who operates your first flight so you know which terminal to go to and which airline's rules and fees apply. If you don't have your confirmation email handy, look up your trip now.
