This may be obvious, but endulge me. I was wondering whilst in the shower...

My flights have EK have decreased quite a lot in recent years, but at the same time from London airports i've seen them grow massively, obviously with their 10 across 777's, multiple 380's, intensive J (on some planes), and all the time with a standard luggage allowance that in Y is more generous (at 30kgs) than any other airline.

With all the additional passengers (20-25% more than many other airlines on equivilant planes) and additional food / drink, and the additional luggage (with additional luggage allowance on that) and famous high utilisation of their planes.

Is EK purely about shifting high numbers of passengers quickly and efficiently? Is this their business model? Surely they have less ability to move freight? EK are so successful - is it because they focus purely on passenger numbers (like I guess Ryanair to an extent - but i'm not comparing the airlines in quality) - or is freight also important side to their business model?
