St. Louis to Atlanta

Frontier is flying nonstop between St. Louis and Atlanta for $82 round trip, a massive 77% cut from the usual $361 fare on this route. That is one of the steepest discounts we have tracked anywhere this week, and nonstop service makes it an easy pick for a quick visit to friends and family or a weekend in one of the South's biggest cities. Travel dates are open over the coming months, so there is plenty of flexibility to find what works.
