Denver to San Antonio
$86$31473% off
Round trip
This is about as cheap as flying gets: San Antonio nonstop from Denver for $86, versus a typical $448 on this route. That covers a River Walk and Alamo weekend for less than a tank of gas, and it's a true nonstop on Frontier with no connections. At this price it's worth carving out a long weekend just for the trip.
