Well, I mean when traveling from West to East a day is much shorter and they don't have to "give" back the day. Well, it was more than a joke since I think as well that there are not many muslims just paying for a flight to have 2hrs less of fasting.
I always remember a working pal who was fasting and always looking to us during lunch time and she was always waiting until sunset but we had fun together. I was just remembering that. During Ramada in winter, Muslims living in Northern Parts (like Scandinavia etc.) do have an "advantage" since the day is not as long as in other countries.
No doubt, if a Muslim asked 411A to decent his plane that you can't see the sun anymore it's nearly cheated
