To answer your initial question 340-200,(at least some of them):
A-330 F/O
1 U$= 3.65 QR) fixed rate.
All figures in Q.R:
-Basic 15500
-Housing : 6000 (5500 if single)
-furniture:700
-transport:600
-utility: 300
-call on days off for duty :750
-Flying allowance 90QR/hour (330 usually fly....85..90 hours/month)
-Meal allowances 2000...3000 QR/month (depends where you fly)
-School :donīt known sorry no kids..
-overtime paid if you exceed 780hours/year(around 270.. QR/hour)
NO annual increase!
End of service benefit 2/3 of the Basic/year
For info today a villa in doha will cost you..15000 QR/Month!
So Be carrefull...DON"T BE IMPRESSED by the salary...you will be probably more impressed by what you have to spend every months..inflation is huge here and looks to me totally out of control,...unfortunatly the salary is not following the same curve!
Check Etihad or Emirates (much ore better condition)if you want to compare.figures are on their web site.
