Southwest airlines if only you fly everywhere. Depends on where I'm headed to and if southwest goes there, I will for sure take them. Pretty much the only airline that doesn't have a baggage fee for check ins. That's pretty awesome! It may not be the nicest planes but it's worth it. People complain about the fabric on the seats are cheap and ugly or the food choices are horrible. To me I have no problem with either. I love southwest. The seating arrangements are by groups A, B, C and you pick your seats group A are the best because you get first dibs on seats. If you have a big family and wants to sit next to each other I suggest you get your tickets as soon as you can. By doing this you have a certain time the morning of before take off to print your tickets to get group A. I would take them everywhere I go if I could. Oh the free snacks, I always have to have their peanuts. Lol
