We have an upcoming flight SAN-DFW (4:04 - 9:09pm) connecting to DFW-LHR (10:10 pm) departure. Flight
#491 is frequently late. We are on business class award tickets. If the flight is delayed from SAN, what's the chance we could get them to move us to the BA flight with leaves directly from SAN-LHR? The 10:10 AA flight is obviously the last flight from DFW. I'd hate to arrive late into DFW with no other options.
