I am confused by the Aer Lingus carry on policy. They offer a "Drop Option". Is that like what we would call "gate check" in the US? Would that mean that I take my bag to the boarding gate and they check it before I get on the plane? I asked the airline but they say they can't help because I booked through British Airways.
I would gladly pay the fee for priority boarding with my bag, but Aer Lingus won't sell me that option because I booked through British Airways. British Airways won't sell me that option because they don't operate the flight.
