OK, not to beat the airfare things to death, but it does look like the Delta flight prices are "flickering" a bit. Not enough for me to regret purchasing airfare when we did. RT NS flights are holding at $590 from MSP to give you a clue. Some of this is definitely Delta, and not just this flight from MSP to MCO. I have a sister trying to book flights from Birmingham, AL to Grand Rapids, MI NS a couple of times in the next few months and those prices have been ridiculous as well without much repreive. There could certainly be summer sales, but not sure we'd feel comfortable waiting that long... pixie dust to those of you who can hold out! Wish we had Jet Blue... or more NS SWA options even!
