The overnight would work BUT, again, Delta has a return flight on the 22nd that gets into PIT a tad after midnight......no overnight needed Yup, it's a pain to get in that late but it's less of a pain than not going at all.

We are returning to BOS just about the same time in January . I chose that flight because of the 3 hour layover in ATL...less stress about getting off SXM in time to make a connection
