What is the maximum time in the air for domestic flights on the islands? (I presume it is not only England when you say domestic)
Let me guess, 1 hr 10 minutes perhaps?
I’d say it is such a waste to mess around serving food during such a short trip.
If you take a bus/taxi/snailrail from London central to Heathrow it takes you 45 minutes or around that. Do you eat then?
Eat before you board, or after.
