Anyone have any good airfare rates from phx to mco in october?

[Disneyfun1]

We are ready to book our airfare for our october trip, but cant find good rates. i check delta daily, and it seems so high, unless the rates are the norm now. right now its about 517 RT each on Delta. we did get $400 in vouchers each from delta for getting bumped last year, but that still seems high, i dont think ive ever paid more than 375 RT from phoenix to orlando in all the years we have flown. should i wait, or get them now?
