Southwest Air is growing; most everyone else is contracting.

The NYT has an article about Southwest Air's purchase of ATA for $1.4B, which is significant in itself, if for no other reason than the fact that I love Southwest for its low prices and no baggage fee (for your first 2 checked in luggage).  But what's caught my attention is the side graphics, showing that of the major US airlines, all but Jet Blue and Southwest have been shrinking.  But whereas Jet Blue is in its relative infancy, Southwest is now the largest US airlines.
