What is the world's biggest low cost airline? Answer - Southwest.
Here's what a NYT article says about them:
Though Southwest has just about the lowest costs in the industry, it now pays the highest wages to many worker groups, making up the difference with higher productivity and by holding down its costs in a number of ways.
In fact SWA skippers are now
the highest paid pilots in the US.
Much more than United, TCK's favourite example when he wanted to further reduce our package.
Maybe the difference between SWA and EK is better managers?
