Even less aggravating - travel on a "real" airline like Emirates. Economy class passengers on transatlantic flights get 2 bags @ 30kilos each. Other routes 1 bag 30 kilos (but their website may have variances to that generality).

I will never fly Qatar Airways again - their customer service skills (especially ground staff and their customer relationship people) are the worst I've encountered anywhere in the world.
