I work for a large International Company UK based, that USED to fly BA.
No longer.
We fly KLM and to be honest the difference in attitude and approach is totally different. One always gets the clear impression that the KLM CC are pleased to see you.
I have also noticed that the dynamics between the CC and the FDC seem to be better as well. It was very interesting and an eye opener to watch a KLM and an Air France flight land within a few minutes of one another.
The KLM team came through Immigration as a sort of happily talking "gaggle", the Air France crew came through as follows :-
Captain
FO (Three ringer)
SO (Two ringer)
Senior Purser/CSD (whatever)
CC in seniority order.
Thankfully I don't ever fly AF, by choice.
I found ultimately that the impression given by the BA CC was that we (I) was just an inconvenience they had to deal with, and that they would be happier if the plane was empty.
