Evanelplus,
Did you actually read the OP? He said:
Realise is not strictly BA's problem in the first place, but we ended up forking out for new tickets due to the difficulty of getting hold of them. And why the incessant reminders to "go online"?!? (the last thing you want to do while moving about abroad and that's if you can get a connection at all....)
"Due to the difficulty of getting hold of them" was the reason given why he believed BA had let him down.
I too have been challenged getting in touch with them, after receiving an e-mail while I was in the UAE, to call them on their toll free number (only accessible in the UK) to deal with them cancelling my flight, without protecting me on interline carriers (as they promised the media they were doing). They shut off access to all the Exec club lines and could not deal with the number of callers on their regular line. Their local UAE offices had no instructions from LON either. I'll repeat myself, BA let me down. To their loss.
