Delta has 809 aircraft. EK has how many?
Is there a point in there? Are you trying to say making a profit with a fleet 4x the size of Emirates' is easier or harder?
I do think, that making a profit in a real country with things like labour laws and income taxes and unions and such, is far more impressive than making one where the regulator is the airline is the airport is the government and you have endless supplies of exploitable cheap labour nearby. It mostly seems the Gulf 3 make money in spite of their management, not because of it. Hell even Air Canada could probably make a regular profit if they could just pay Indians to load their planes for a few hundred bucks a month and work their pilots 95 hours/month lol.
Soon enough, I suppose.
