When wondering, “What is the best day to buy airline tickets?” studies suggest that Tuesdays and Wednesdays are ideal. On Tuesdays a lot of airlines offer discounted flights and by Wednesday, other airlines frequently match those fares, providing passengers additional choices. Because fewer people are shopping during this midweek period, there is less competition for deals. Booking flights early in advance, ideally several months before peak trip periods will ensure lower airfares. Although there isn’t a magic formula it can be simpler to find the best deals if you are aware of these tendencies and are flexible with your vacation dates.
