When is the best time of the week or day to purchase cheap international flights?

I heard airlines release hold flights in the early morning and late at night. Has anyone found this to be true?When is the best time of the week or day to purchase cheap international flights?
Typically, airlines will load new fares late in the evening, but there are instances where sales can occur that last several hours at the most, so the price could well change during the middle of the day. Add in the complexities of airline pricing, which price tickets based on available inventory on a specific flights, and you'll find that tickets can change on a nearly constant basis.



Ultimately, what this means, in my opinion, is that there really isn't a best time of the day or week to buy cheap international airline tickets, because of the way that pricing works. Additionally, there are quite a few other factors that go into determining the price for international destinations, such as demand of the route and destination, the minimum stay, and so on. The page linked below has some discussion on some of the things you can do to improve your chances of finding a cheaper ticket.
With all the flying I've done. Best times to book is as early as you can say now and you want to fly out in 1 Month+ and try to book around Tuesday to Thursday. Wednesday being the prime day.

Best times usually earliest or the latest flights you can get.



Most people want to fly out on a Monday and come back on a Friday.

Weekends are even worse avoid them.



Also you can save even more if your willing to have lay overs. Basically these are the flights that you pick up when they're returning a plane to its start location.



If you're going to book online I recommend using www.hotwire.com I had bad experiences with the other sites I've used this being the best.When is the best time of the week or day to purchase cheap international flights?
