I would like to share this interesting article found in the economist about emirates! Since it is subscription only let me summarize it in a few sentences:
Common wisdom in aviation said that the no-frills could only be applied on relatively small journeys. Passengers want frills on these flights and anyway long distance flights and fuel eat away the savings made by a quick turn-around at airports. A few airlines tried but failed.
Today though Emirates seems to be the leading one thanks to its low cost structure. Goldman Sachs has calculated that Emirates profit-per-seat matches Ryanair's one, twice de level of Lufthansa and 2/5 more than BA.
It's main advantages: A home base where there are no corporate and income taxes, and the backing of the ruling family in Dubai. But the best savings are made on cheap labour, round the clock operations, low airport fees.
With the A380 the paper even guesses that u could go to Australia for €400 return!
But with Etihad and Gulf airways entering the fray, over-capacity might lead to a price-war, with even cheaper flights

ps: Ok I hope I haven't done a copyright infringement here. If one of you has any doubts tell me and i'll mail the Economist for their approval! In the meantime I hope U will like these hard facts!
