What airline is best to travel to middle east?

out of these EL AL, Emirates, Gulf, Etihad, EgyptAir, Or Kuwait Airlines

Try Emirates.... the best

EMIRATES - I would give them a 10 on 10 .
Their service is superb and their quality is extraordinary.
Happy flying !!!!!!!!!!!!!!

Depends on what your definition of best is. For me, I just been to Doha, Qatar last year December, taking Qatar Airways. The seats are quite spacious & definitely have a lot of leg room for me, a 5 ft 4 person. As for service wise, it's a little on the downside. Air stewards & stewardesses are a mix of different culture & their service is rather not as good. Most important is your airfare budget. Maybe you can give other airlines a try, you might be surprised (be it good or bad) at the end.

Qatar Airlines

Emirates out of those. However, I hear very good things about Qatar

Emirates
