I live in south jersey and fly to Disney several times a year. While we have a SW CC that we pay anything we possibly can with, we rarely fly SW to Orlando anymore. We save our points to fly to the islands instead.
We've found Frontier to be MUCH cheaper. Now, we are frugal flyers. We do not pay to pick seats or check a bag or bring a carry-on. We make everything fit in our personal items. We usually pay less than $100 round trip on Frontier. And our flights are almost always late. We just plan to never be on time. For us, a family of 5, it's worth the hassle and the uncomfortable seats to save over $1,000.
