If you need a late-winter getaway to a sunny destination, a sale on midweek flights from Frontier might be your fastest path out of town.
The airline is currently running a sale featuring $39 one-way flights all over the US. The cheapest tickets are for flights on Tuesdays and Wednesdays, like the route below between Atlanta and Trenton for $76.60 round trip. If you're a Deals Den member with the airline, tickets are even cheaper, coming in as low as $29 for a one-way fare.
To get tickets in the sale, you must purchase by 11:59pm ET on January 19, and the trip must be taken by March 7. (Though, if those dates don't work for you, Frontier frequently runs sales. Just wait a week or two and you might get lucky on the next one.)
The options are plentiful. There are more than 200 routes with one-way tickets for $49 or less right now.
