Plenty of good contributions here - anything in “daylight” hours at departure point with a breakfast / brunch offering and then not much else…that now includes morning (pre-1130) departures to the US which I will now avoid
BA 295 to Chicago now sounds nasty, for example - get up at 7, LHR at 930, departure 1115, get given a stupid brunch instead of actual lunch, at around 1300….arrive Chicago starving at 2pm local with the entire afternoon to get through - no thanks
