Spring break might be over, but that doesn’t mean you can’t still take an epic trip before summer hits. Frontier Airlines is making that last-minute spring vacation as cheap as it gets, with fares as low as $20 one-way throughout the US. You can fly from pretty much any major city in the country for between $20 and $40, so it’s worth perusing the extensive spring sale site to see which offer is the best fit for you. Here are some of our favorites:

The sale is valid through April 11, and for travel dates between April 16 and April 28. So if you want to take advantage of it, you’ll have to not only book quickly, but also be prepared to take some time off work in the next few weeks.

Note that Frontier is a budget airline, and fares do not include checked baggage or seat selection. So if you do need to check a bag, be aware that this will add to your costs.
