Plane tickets from $29 one-way? Yes -- if you can book a ticket on Frontier Airlines by the end of the day tomorrow!
Snag the $29 fare for dozens of travel routes that include the following city pairs: Denver and Las Vegas; Atlanta and Cincinnati; Philadelphia and Atlanta; San Francisco and Phoenix; Dallas and Phoenix; and Washington Dulles and Chicago’s O’Hare International Airport. This rock-bottom fare is for travel between July 18 and August 31 only.
Some of the higher-priced fares ($49-$59 one-way) are good for travel dates as late as this October 20 -- although some do not go into effect until August 22. For example, you could fly from Indianapolis to Atlanta, or from Philadelphia to Chicago, for $49 each way anytime between August 22 and October 20.
Several smaller cities are included in the sale, too. You'll find flights to Austin, Orlando, Trenton, and Raleigh-Durham.
