According to a new study, there really IS a sweet spot to buy plane tickets and get the best price!

CheapAir spent the last year looking at about three million airline trips. They tracked ticket prices from about 320 days before takeoff all the way up until the day before, calculating precisely which day each one hit its lowest point. So, when's the best time to buy?

54 DAYS BEFORE TAKE OFF BUY YOUR TICKETS!

That's when, on average, domestic airline tickets are at their absolute lowest price. If you miss that window, then book between 112 to 21 days before your trip. That is within the 'prime booking window'.

I've always thought that you get the lowest prices when you book 'at the last minute.' This couldn't be further from the truth.

They really dove into this research and dissected it. If you want to do a little homework, it may just save you hundreds of dollars!
