Last year we purchased tickets from MHT to MCO June 16-21 on Southwest. THe original price was $69 each way but then the price dropped to $49 each way and we were able to get the $20/person refunded. We had a blast but boy was it hot. Being from Maine, I was just not ready for that. I think the later in June you go, the prices increase. If you can go within the first 3 weeks or so. You should get a good price.
