So I think I know the answer to this from researching, but just curious what others may be experiencing with GAs. Booked on AA (ticket and metal) BOS - JFK. If I’m able to get to the airport earlier there is a BOS - LGA on JetBlue metal, but is actively sold by AA as part of their Northeast partnership. I found an article and post that says you can’t do a same-day confirmed seat between the two airlines, but curious if anyone has had success standing by in the airport? Thanks.
