There is no single spring break. Colleges and schools break at different times from late February to mid-April, but demand piles up in the two weeks around the middle of March, when most college breaks overlap, and again around Easter, which falls on 28 March in 2027. Those are the weeks when flights, hotels and rental cars cost the most.
The week before and the week after often cost noticeably less, even for the same route. If your school or employer gives you any choice, picking a quieter week is the biggest single saving, ahead of any booking trick.
