I received an email from BA that my Sept 3 LHR-MEX award departure time was changed by 2 hours and 45 minutes. This will make me miss my next flight on AeroMexico MEX-GDL which is not on the same ticket. I searched BA website and the Internet in general to see if I could change the destination on a BA award ticket and found no information. Even if there was a fee, I would change the destination to GDL. I know it is not possible on AA awards. Does anyone know if it is possible on BA?
