I was going to suggest asking AA if they’d reroute you through NAS on the BA253 flight NAS-GCM but after some research and thought I see there might be a few complications with that:
— BA don’t fly that route on Tuesdays
— Not sure if that segment is even bookable as a stand-alone flight. It is really the second leg of a one-stop “direct” flight LHR-NAS-GCM. Does anyone know if it can be booked on its own or combined with other AA flights like this?
