Surely flying FC is about lifestyle - rather than perks - I normally don't catch the bus at the airport (Y) only occassionaly taxis(J) normally have a limo waiting. Same with hotels normally book a suite on a club floor - thus have personal space and avoid the coach parties at breakfeast
BA might not be the best - but their service is consistent and adequate, CX is often better but sometimes ... As a regular traveller flying BA takes the hassle out of it. It is like a comfy cardigan.
