Seen below, we found seats departing BOS on Tuesday, March 27, returning from CHS on Wednesday, April 4, 2018. The same dates are available for flights to Savannah SAV as well.
Other dates are available for travel in January through early-May on Tuesdays, Wednesdays, and Saturdays. Keep in mind that these fares are American Airlines Basic Economy fares, which means your carry-on allowance is just one small personal item such as a purse or small backpack up to 18x14x8 inches. Consider the higher regular economy fare if you need more carry-on allowance.
See our Boston BOS fare listing page for a complete look at current finds.
