American Airlines is trying to go toe-to-toe with Frontier on this route, so that means savings for you. While Frontier is still cheaper, if you prefer flying on a legacy carrier then this is the choice to go with. Fly nonstop from Charleston to Philadelphia for $75 roundtrip this winter.

Departure days are limited and only available on Wednesdays and Saturdays starting in early December through February 13, 2019. December dates, however, are relatively limited, so your best bet is in 2019.

Searching on American's website, I found seats departing CHS on Wednesday, January 16 and returning from PHL on Saturday, January 19, 2019.
