What perks could you possibly expect from a budget carrier !
If it were flights you were after would'nt it be cheaper to get a confirmed seat ?
btw - Qatar at Lhr are another example, Servisair staff in Qatar uniforms.
Personally if i worked on a contract like this - i wouldn't want to wear their uniform.
All the hassle for what ?
I also think it is very likely that GH Staff who were Airline Uniforms usually tend to think of themselves as working for the airline - that is until the contract changes hands !
