I am a frequent flyer. My personal belief is that in my opinion all US airlines are very similar. I have flown almost 3 million miles with Delta. I stay with them because of points and they are not any better. They use to be very good but not any more.
Flying use to be fun but my experience any more is that due to security which is necessary, airline cost problems and delays, driving is much easier even if a thousand miles is involved.
I have found that a rental car gets me there just about as soon with my baggage intact, no delays and much cheaper.
I hate the hassel of the airport.
