Is it me or are EZY, FR, AB driven by world domination?? I know thats a bit extreme but still Easyjet, Ryanair and Air Berlin are slowly occupying the 'Europe Scene'

im seeing in the next few years Ryanair Asia or Easyjet Brazil or Air Berlin America.
Why don't we see other airlines doing the same such as American, Air Tran...... I was just wondering thats all......
