Apart from water, it's my main drink on BA flights. Being a posh northerner, I'm more coffee normally, but tea suits in the air on BA and a scant few other airlines such as Aer Lingus and NZ. QR is always interesting, since sometimes you get a cabin crew member who knows what they are doing. I discovered one of them was a graduate of my former college, the LSE and had been taught to make tea in the same hall of residence kitchen that I used umpteen decades beforehand, Other attempts can be totally hapless, particularly making tea with water and milk pre-combined and warmed to about 50c - and various appalling permutations that would need trigger warnings.

The main problem I have with BA crew making tea is that most of them are female and based in southern England. I haven't found a set of words that gets over the need for tea to be made with sufficient milk to be caramel in colour, rather than bright white..On LNER it's the opposite, the crew may be from Leeds or Doncaster or somewhere equally grim and 2 drops of milk is your lot. Actually it's the weird milk jugs they use that never seem to express more than a weak trickle of milk no matter how full they are. Some BA crews allow me to pour my own milk from the carton into the cup, that's probably works best for me.
