While there isn’t a magic “best” time to book summer travel, there are a few things that can help ensure smooth sailing.
If your timing is flexible, traveling during “shoulder” season (between peak and off-peak) can be easier.
For domestic summer travel, keep an eye on flights for several months before your planned trip.
Usually, you’ll want to book an international flight sooner than a similar domestic flight. If you wait until the last minute, you could see the price rise dramatically.
