Frequent travelers or those looking to book a trip will score the best fare prices when they purchase tickets about 70 days in advance of their flights, according to the most recent annual study by CheapAir.
They analyzed 917 million airplane ticket prices at the time of purchase to uncover this prime purchase window which is up from 54 days during the previous year. Although many casual flyers might guess that tickets will be the cheapest when booking as far out as possible, there could be a $50 premium on tickets purchased 169 to 319 days in advance and a $20 premium for those at 122 to 168 days out.
The least popular days to fly are Tuesday, Wednesday or Saturday, which also make them the cheapest. Avoid Friday or Sunday, which are the most popular days. Also look for very early or very late travel times to find better deals and discounts.
