Most people know there are, broadly-speaking, days of the week that are the cheapest to fly. Past studies have shown flying on a Tuesday will often help you find the cheapest ticket possible.
A new study from CheapAir.com dug through almost one million trips and more than 311 million airfares to illuminate how you can cheaply travel from the U.S. to Europe over the course of the summer. Much of the standard wisdom -- like flying on Tuesdays -- applies here, but summers are also a different beast with holidays and peak travel season in many locations. CheapAir.com found Monday, Tuesday, and Wednesday are the cheapest days to fly, with Tuesday being the cheapest of those three. Flying on a Tuesday saves an average of $129. Meanwhile, Saturday is the most expensive day to fly.
Additionally, there are hot times, like early June, where tickets are going to be cheapest. Here's a look at each summer month's cheapest days.
