That's completely incorrect. If you think that LCCs haven't gotten govt assistance monetarily, through asset seizures (forced divestitures) and redistribution, sweetheart deals on airport usage/fees, etc, you do not understand anything about the business.

Example: How many airlines were allowed to bid for the 2 gates at Dallas Love that American was forced to divest? Exactly one. Virgin America.
Just one of many, many examples.

As far as post-911 government bailouts, do you know how much United, one of the two airlines that lost aircraft on 911, received in government bailouts?
