Frontier has been running a slew of sales recently and the deals keep on coming. For today only, Monday, travelers can get 90% off their Frontier bookings with promotion code "SAVE90".

Here's the catch: you have to take the trip before Oct. 2, 2019, which is less than a month away. The discount is also only valid on travel Monday through Saturday, so no Friday to Sunday weekend getaways; instead you'll have to go for a Friday to Monday if you want to score the 90% off.

One of the most appealing deals is Orlando (MCO) to San Juan (SJU) for $104 round-trip as soon as this weekend.

Note that you'll have to pay extra for carry-on and checked bags as well as seat assignments if you don't want to let them pick for you.

To search, head to and see if your dates and cities are available. Don't forget to use the promo code "SAVE90" to get the discount.
