HT Thanks for the support. A slight correction though, the LHR - Gibraltar flight was flown as booked. It was the Glasgow - London first leg that was involuntarily rerouted by BA.
So one could argue - how come the Much Beloved was allowed on the LHR - Gib outbound leg if she'd no-showed on the first?
Incidentally we have had a response from BA 9 days after the event. A standardised email asking for details of the problem!
And no, I don't think 9 days to "answer" an email is acceptable
Hey ho
