Southwest was always my number one due to the culture, MCO base, and job security and I was fortunate to have been hired by them, but I have started to realize that Southwest is best if you live in a junior base. American never appealed to me, but now that I see how senior Orlando is I'm starting to consider pursuing American for the Miami base. With that said if you want to live in Dallas or Phoenix you can plan on having a great quality of life as both those bases have gone pretty junior. Best of luck with the decision. It's not an easy one to make!
