Ive flown with Etihad many times,I'd recommend them,never with Emirates.....I flew Qatar to Mumbai once (2006?) and was scammed at the airport in Mumbai by crooked Indian staff.....the last days of paper tickets....I never recieved any compensation from Qatar and since then have refused to fly with them....saying that,if they came in with a really cheap flight to Los from Manchester,then I would have to review my high moral principles ,and book the flight.....
The big plus with Arab airlines is ......Theres no chance of them being hijacked by Isis/AL Q ,or any other mad muslims
