Travelers can snag $20 Frontier Airlines tickets on routes all over the country including Houston to Atlanta, Dallas to Cincinnati and San Antonio to Denver.
There are some restrictions. Frontier's $20 flights are valid for travel on Tuesdays, Wednesdays, and Saturdays from August 15 to October 4. There is one blackout date: September 5 (the Tuesday after Labor Day.)
If you do plan to fly Frontier, remember the airline is very similar to Spirit Airlines and customers face fees for almost any amenity above basic transportation, which includes baggage and seat arrangements.
