Just a catch up to say all costs refunded to SIL and families by BA, so a happy ending even if a little trying for them at the time it was occurring. Impress to inflate if it helps Lufty have done it to me twice as well in last 18 months or so. Both were re route and alternative departure time due to connecting flight being cancelled one from Middle East with Oman Air - earlier overnight into Frankfurt rather than Munich and the other similar inbound from Singapore. It seems to be the European short haul Lufty which is the problem for me, not sure re BA.
