Well you have rather proved my point there Lucifer:
Emirates = Middle Eastern, Low cost base, government funded.
Ryanair = Western LoCo, the only one, as I mentioned
SkyWest Airlines = US Regional (have you seen what they pay?)
ExpressJet = US Regional (See Skywest)
Jet Airways = Asian, low cost base
Mesa Air Group = US Regional (See ExpressJet)
Gol Transportes Aereos = Brazilian LoCo - developing world, low cost base
Republic Airways Holdings = US Regional (See Mesa Air Group)
FL Group = Icelandic Holding Co - what else so they hold
Kenya Airways = African Major, low cost base
Evergreen Intenational Airlines = US Charterer (lots of work for Uncle Sam)
Middle East Airlines = Lebanese - developing world, low cost base
ASTAR Air Cargo = US Cargo (formerlly DHL? DHL still flying.)
Air Transport International = US Charter (lots of work for Uncle Sam)
Apart from Ryanair I don't see a single recognisable western major in there. Lots of developing world carriers, some with government backing, and a lot of US regional carriers. You're hardly comparing like with like are you? Unless you think operating a couple of hundred commuter aircraft as a franchise is the same as operating 160 widebodys and another hundred or so 100+ seaters under your own brand. I don't even see Jet Blue in there. Show me the major carriers making a 10% margin in any developed nation that has any form of social/welfare infrastructure.
