You hear all sorts of vague theories about the best time to book plane tickets to get the best deal so it’s nice to see a study like this that eliminates the fuzziness and gets right to the point.
A website called CheapAir.com monitored prices for four million flights last year, and found the absolute best time to buy a plane ticket is exactly 54 DAYS before your trip.
That mark is for domestic U.S. flights. If you’re going to Mexico, book 89 days in advance. 101 days in advance for the Caribbean. 129 days in advance for Asia. And 151 days in advance for Europe.
The only time the 54-day window doesn’t apply is for Christmas or Thanksgiving flights. You’re best off booking those SIX MONTHS before on June 4th.
