Philadelphia to San Antonio
$178$40156% off
Round trip
San Antonio is 53% off its usual fare from Philadelphia at just $178 on Frontier, not far above the $132 all-time low we track. It won't turn heads like a beach trip, but at this price it's an easy, cheap way to hit the River Walk and Tex-Mex scene.
