Mondays can have us all feeling a bit of wanderlust as we get back into the swing of the workweek. If you’re feeling especially spontaneous today, these are some of the last-minute flight deals you can book for this upcoming weekend.

Many of these deals — like Colorado Springs (COS) to San Antonio (SAT) from $49 round-trip — are a part of Frontier’s flash sale, which is offering 90% off bookings made today, Sept. 9. However, it’s still possible to grab a cheap flight without the generous discount. Just be sure to act sooner than later as prices typically go up closer to the departure date.

If you’re a business-class-only flyer, these fares probably aren’t for you. But if you’re an adventurous reader aching to go on a trip and willing to pack light, check out these last-minute deals. Be aware of extra fees and restrictions, because low-cost airlines such as Frontier and Spirit all charge extra to choose your seat and to bring a large carry-on bag. Although these budget carriers tend to get a bad rap, you may end up pleasantly surprised, like TPG himself when he flew Spirit (and he wasn’t even in the Big Front Seat)! The same goes for Frontier. Bottom line: if you’re in the market for cheap tickets and want to get away as soon as this weekend, this is a great way to go.

If our example dates and times don’t fit your schedule, play around with the dates on Google Flights as there are often other times available for about the same price. All of the routes listed have flights available under $150 between Sept. 13 and Sept. 16. Also note that most of our example routes are also available in the reverse direction.

If you’re looking to get the Spirit deals even cheaper, you can often buy Spirit flights for less at their airport check-in counter. However, it’s not always guaranteed and sometimes the limited savings may not be worth the hassle — it really just depends on how flexible you are.

Worried about Spirit or Frontier’s reliability in case of irregular operations (IROPS)? You can buy insurance through Freebird for $19 one-way, and they’ll rebook you if your flight is delayed more than four hours or cancelled.

To search, head to Google Flights and enter your origin, destination and stopover cities. Scroll through the calendar function to find dates and prices that work for you. Finally, click through to book directly with the airline or through an OTA like Priceline or Expedia.
