I'm looking for a good price MSP -MCO for December, too. Last year, I was able to snag $160 RT fares on Delta. NW wanted over $300 for their non-stop flights. For that big of a difference, I was more than willing to make one connection. Hoping for the same deal this year, but that may be wishful thinking. Right now best I've seen is $258 on ATA and $286 on NW. IMHO, $258 is too much for a flight with connections and $286 is still too much for non-stop.
Since there's still a lot of time, I'm just in a holding pattern. Hard to be patient, but I think it will pay off. If I see a non-stop on NWA for under $250 RT, I'll probably take it. For a one stop, I'd need something less than $180 RT. Still hoping Delta will have a sale with connections in Cincinnati, but it's still too early for that. Probably won't fly any of the carriers currently in bankruptcy unless the IRAQ situation gets resolved very soon. IMHO, the industry isn't doing well enough to trust those carriers to make it out of bankruptcy as long as IRAQ/terrorism is hanging over our heads.
I'll post if I find a good deal. Hope you will do the same. Good luck to all of us MSP people!
