Amazing BA crew from LHR-BCN-LHR. They couldn't have been more kind or understanding. When we walked on I just inquired about nuts on the aircraft and shared that my child is severely allergic. They immediately offered and said they wouldn't serve ANY of their nut products onboard, in any cabin. They said "Of course! You can't be too safe ❤".
She then proceeded to tell us that the policy of the airline is not to refrain from serving nuts because they cannot control what others bring on board. She said she can lose her job for not serving the nuts and that if anyone in first class does ask her for the nuts she will "definitely have to give it to them because when people fly in first class, they "Expect Their Nuts".
