Everyone loves to get away, but no one enjoys paying for the jet-set life. If you have some flexibility in your schedule, focus your search on flights during the middle of the week, when demand is lower. CheapAir has found that flights on Tuesdays are on average $85 cheaper than they are on the most expensive day of the week to fly, which is Sunday. Wednesday and Thursday flights are often considerably less expensive than options on Friday, Saturday, Sunday, and Monday.
Tuesday afternoon is the best time to purchase airfare, according to FareCompare. US airlines tend to start discounting their fares late on Monday or early on Tuesday, which sparks competition among them that settles down by Tuesday afternoon. You’ll have the best selection of the lowest prices then.
