I know it's Monday and you're busy "working" (i.e. hiding in the bathroom at work), but I need you to stop, shut up, and read. Frontier Airlines is is running a flash sale with 90% off flights right now -- for one day only. So if you know what's good for you, you'll drop everything -- including, but not limited to your job, kids, house plants, etc -- and book a trip.
You really don't have time to think it over either. Throw caution to the wind and whip out the Visa. According to The Points Guy, this is a flash sale, meaning you have until midnight on October 14 to lock down these deals.
The bare bones, budget airline has one-way fares starting at $18 and round-trips for $37 to tons of places across the United States, including New Orleans, Austin, Chicago, Nashville, Boston, Miami, and even Puerto Rico.
