Ramadan Kareem Airmann
You ask a very good question, and as I live in UAE, I see the situation first hand.
The general responsability of Muslim pilots is excellent. and the travellers exemption is well accepted and understood.
I am more concerned at 4.30 every afternoon when the mad rush for Iftar is underway.
Especially the first few days, and the starvation is most noticable.
Do what your concience tells you, and ignore the rest of PPrune.
