Well, at least my airfare hasn't gone up! It hasn't gone down, either! We booked our August flights on Christmas Eve, and they are still the EXACT same price. I have been watching December airfare, and it is also the SAME price as the tickets we bought for August.
Last year we booked flights in April for travel in October. Those suckers jumped in price so many times that at one point they were TRIPLE what we paid. Interesting. Overall the cost of non-stop flights from Dallas to Orlando have gone up about $35 per ticket since November of 2004. Once in awhile I see a better deal, but so far we haven't been able to take advantage of any of them!
