Qatar Airways is one of the best emerging airlines in the world, i understand that they dont treat their ground staff that well because they are laborers, you will see that here alot, the expatriates who work labour jobs here usually get treated very unfairly, but if your husband is in a management position in Qatar Airways, i am sure they will provide you with a car that fits your family style, they will provide you a house big enough to fit your family, most likely in a compound, and since you are British, i beleive they have schools here that provide British education probably better then they do in the UK, and if you are british citizens, i think it is free for your kids, such schools include, Doha College, and Doha English speakin school, i went to Doha College, and when i used to study there, british expatriates were provided free education(from what we heard atleast), but if they dont, Qatar Airways im sure will provide a schooling budget for your kids. Dont be to stressed about it, they usually, treat expatriates in management positions very well, and that you will see when you get here.
