I had a business trip in Tampa and decided to give Southwest Airlines a try, since I usually fly with JetBlue. The fairs were very reasonable, the staff was courteous, and I enjoyed the "no assign seat rule". It makes boarding the plane go so much faster and the aisles clear fast. You don't have to wait for passengers to look and find their seats, just sit where you like. Another reason why I like Southwest Airlines is you're allowed two carry-ons for free. I don't usually fly with a lot of luggage, but to avoid the check-in luggage process is a HUGE PLUS.
