Average flight costs?

[TOBS2010]

I am considering planning a trip to Disney this summer. I have started to look at airline prices flying out of Detroit. Just curious what the average costs are airfare. We likely wouldn't go until July or August--but just trying to figure out what a "good" price would be to jump on or if I should wait it out. Thanks!

I fly out of DTW also, anything under $250 is a good price. I usually buy airfare about four months in advanced except when we go to Disney, then I buy about7-9 months in advance, that just seems when I get the best price.
