Truth of the matter is that EK, EY and QR are big airlines and u will only be a number there. On the other hand GF is very much a personal and frienship orientated company and everybody knows everybody..Those who moan and groan are not forced to stay. They can always pack and leave cause wherever they go, they'll always end up finding faults.
Gulf Air truly is a great airline to work for. It has it's ups and downs like all major carriers in the region but nowhere near the scale of those other three carriers u mentioned. As Hunter said, pay a visit and decide for yourself.
Dont listen to some sad bunch here who have nothing better to do than whinge...
