Frontier Airlines has a flash sale that has some really good deals if you’re able to book by tonight. Travel must be completed between January 29th and March 7th. For example, I’m seeing one-way flights between Long Island (ISLIP) and Orlando for $20 each way. Los Angeles to Denver is also $20 each way and same with Cleveland to Orlando. You can go to their website here and see if your destination is included in the flash sale. Just be mindful that Frontier is an ultra low-cost carrier that will charge for any bags that don’t fit under the seat. If you’re on the fence about a trip, you can book now and cancel within 24 hours for a full refund.
