I have flown Southwest Airlines many times to all different areas. When I had friends living in Washington DC. I always flew Southwest. They are one of the few airlines to offer nonstop flights to DC and the price was almost always the cheapest. They also offer non-stop service to Orlando which is very nice as many airlines have layovers that really extend the trip. Southwest often runs great internet specials and if you are watching for them you can often get really great fares. For example, a friend and I flew to Fort Lauderdale for 120.00 each. That was a great bargain. My flights have always been on time, clean, well staffed and above average for service. I look for southwest schedules when I get ready to buy because my experiences have been so good.
