I'm looking at a flight from Dallas, Texas to Fort Myers, Florida in April....Cost: American Airlines $357 - Spirit Airlines $71. That is a HUGE difference and that is why I will continue to fly with Spirit Airlines. If you do any research on Spirit Airlines, you will see tons of negative comments. I flew with Spirit last week and have no complaints. The plane was looked new and was very clean. The staff was nice and the boarding process was easy.
