On average, you’re most likely to get the best airfare deals, if you book 56 days in advance. The most expensive day to book is typically on the day that you’re planning to fly.

For the lowest prices on airfare, the best day of the week to fly is on Tuesdays and the worst is on Saturdays. Flying on a Tuesday also means a short week on your return if you have to head straight to work on Wednesday.

For the best time of the day to fly, evenings flights (from after sunset until sunrise) are usually cheaper than morning flights. Your time of arrival depends on your destination, so while we can’t be sure if you’ll lose or gain time, flying in the evening can save you money.
