As a frequent flier and raving fan of Southwest, I've wondered what would change when they once again paid the same price for fuel as the legacy carriers. Today I stopped worrying. This acquisition ought to buy Southwest at least 10 more years as #1.
I'm also a frequent flier of Air Tran. AFAIC, except for Jet Blue, no other carrier is in the same class as Southwest and Air Tran. I have little doubt they will figure out how to make this work.
Now if only the feds don't fuck this up...
