We are planning on visiting in June from Denver. I have been checking airfare for some time now. It is consistently $645 (US Airways through Phoenix). For a very breif period a couple months back it did drop to $493 but we weren't ready to book and even that was way higher than we have ever paid before. Now we are ready and I can't find a deal.
Do I book now at $645 or is there a chance for a "sale" or will it go up even more if I wait? Not sure what to do. What are the airfare trends? Is it high from everywhere?
