I will start off saying that I love Southwest Airlines. This airline has made it affordable for our family of five to go to Disney World. We can fly from Manchester New Hampshire from $89.00 to $159.00 each way. We usually will be able to snag the $89.00 and sometimes even less flight. It basically is fist come first served pricing structure.
If you know when you want to go you have to keep your eyes open to get the best deal. It is a no frill airline. The will offer you a soda and a bag of peanuts and that is it. We always bring our own snacks. They are always on time and the staff is very courteous.
The one big problem that people find with this airline is that your seats are not assigned. We have never had a problem with this. My husband will go on line within the time alloted and he will sign us up getting us in an early lot. They will allow you on the plane by A, B and then C. We have always received an A. We have always been able to sit together and we were would have chosen.
I know that with other airlines we would have to pay a lot more. We also love the convenience of flying out ot Manchester, New Hampshire instead of the more crowded and traffic ridden Boston airport. Southwest gets both of my thumbs up, way up!
