Flew to Hong Kong with BA and was not happy about having to pay extra to sit together (2 adults and 2 kids) - I thought that was what flying with a high quality legacy airline was all about?
The flight back was cancelled due to the aircraft going tech. Got a flight with Lufthansa instead. Made the best of a bad job as far as organising seating was concerned when we checked in online (not much available and no option to pay extra to sit together) but by the tine we arrived at the airport someone (presumably a person!) had re-allocated our seats so that we were all together. Very happy about that - top marks to Lufthansa. In the end got £££ in compensation from BA for the cancellation, plus the additional fees we had paid to sit together, and we only got home 2hrs late!
