The short answer

On the 34 routes from Phoenix we have booking data for, buying at the best time saved a median of about 36% compared with booking in the last two weeks before departure. The gap ranges from about 16% (Kona) to 61% (San Diego). So a last-minute trip is not always expensive: on some routes it costs only a little more, and on others the last-minute fare has been more than double.

How to find a cheap last-minute flight from PHX

  • Be flexible on where, not just when. If the trip is about getting away rather than one city, compare a few short routes. Our weekend getaways guide lists 15 places within about two and a half hours of PHX.
  • Check every airport. LA has five airports with nonstops from Phoenix, the Bay Area three, and Dallas and Chicago two each. Fares between them can differ a lot, so compare all of them.
  • Look at Mesa Gateway too. Allegiant flies from Mesa Gateway (AZA) to around 40 cities. It is worth a look if it serves the city you need.
  • Fly midweek. Tuesday and Wednesday departures are usually cheaper than Friday and Sunday, which matters most when you have little time to shop.
  • Check one-ways. Two one-way tickets on different airlines can beat a round trip.
  • Watch real fare drops. Our deals page shows fares from PHX that our daily scan found at least 20% below the typical price for the dates.
