I know this isn't strictly BA related, but the quality of answers here are invaluable..
Just landed this morning from HKG on CX. My onward flight on BA from LHR-GOT was cancelled... so I gave up, got my luggage and went home as I was due to fly back to London tomorrow morning on another airline to end my ex-EU.
As it was all ticketed via CX, I rang them and asked them to refund whatever can be salvaged for the BA LHR-GOT portion of the ticket, and they are refusing to refund anything - not even taxes. They're only offering me rebooking, which doesn't really work.
I shall try again in a bit, but to be sure.. tHow would I calculate what is owed? FWIW my fare calculation is below.
Edit: As far as I can see, I would be due BA YQ of £21.50 (only one leg flown, so half of £43), and about £20 in passenger service charges, plus whatever CX works out to be the fare for the BA part of the leg.
