Because I'm from the East Coast and currently live on the West Coast, there's a few times a year I go back and forth. And sometimes I also make jaunts down to Texas. Because of this, I've found Virgin America to be the best middle ground (for me) in terms of economical and comfort. I will fly Southwest when I have to and it makes sense, I've flown other airlines across country, but Virgin tends to me #1 choice.
