of airline pilots in Doha now. I think because they are expanding so much they are hiring lots of new pilot. As Nath say ... the only problem is housing, one pilots family i know their house going up from 7.000 to 10.000 (who said the law of 10 percents increament cap works in Qatar???).
So you should just ask a house instead of allowance when you decided to relocate to Doha :-)
All the best
