Tuesday is often believed to be a cheaper day to book flights because airlines often release sales starting from Monday night or Tuesday morning. This means that if you happen to look at flights on a Tuesday after a sale starts, you will probably get better flight deals than you would if searching on a Saturday.

What time is cheapest to buy flights?
The best time to book airfare is within a window of 21 to 74 days before you plan to fly, and the cheapest tickets are generally on midweek flights. You can also save if you use an airline miles credit card to book flights that help you earn miles or points toward future air travel.
