  • When a trip mixes BA and other airline codes, the baggage allowance follows the most significant marketing carrier under IATA Resolution 302, and your e-ticket receipt should show it.
  • Seat choice, special meals and changes may need to be made with the operating airline. Inside the last 24 hours, go to whichever airline is flying you.
