Airfare deals are typically only available on limited dates. We recommend you use Google Flights to find dates to fly, then book through an online travel agency such as Orbitz or Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using The Platinum Card® from American Express, you’ll need to book directly with the airline or through the Amex Travel portal to get 5x MR points. Remember: Fares may disappear quickly, so book right away and take advantage of Orbitz or Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.

Frontier Airlines is at it again with one of their fantastic flight sales. This time, it’s about as cheap as it gets with $15 seats available on a variety of routes with no Frontier Discount Den membership required. Keep in mind that Frontier charges extra for everything from a carry-on bag to a seat assignment to a can of soda. Still, even if you choose to bring a full size carry-on bag aboard your flight and lock in a specific seat, you will likely end up paying less than on full-service carriers.

This sale ends tomorrow, so you’ll need to act fast. As is the case with any Frontier flash sale, there are blackout dates. To take advantage of these cheap fares, flights must depart between Aug. 16 and October 10, 2019 on select dates (so use the Frontier calendar search view).

To book the lowest fares, you will often have to book on FlyFrontier.com and head to the flight sale section.

When flying an ultra low-cost carrier, if you are worried about what happens in the face of flight cancellations or severe delays, consider looking into Freebird.
