Sorry rupetime, you are quite mis-informed.
A few airlines have not over-expanded, or purchased bankrupt carriers, or had excessive salary demands shoved down managements throats or forgotten 'customer service'.....the list goes on.
In times when traffic disappears in large numbers, an airline that has been well managed will survive, and without a bailout from any government.
Southwest comes to mind.
Airtran is another.
Even Continental could be added to the list.
The folks at UAL and AA will just have to suffer the problems that poor management(s) have provided in recent years.
And, a turnaround at US Air is not out of the question. Just might happen...the folks there have 'woken up and smelled the coffee'...I hope.
