JetBlue has round-trip flights from Dallas (DFW) to Boston (BOS) for $137, NONSTOP. Flights September to December. Departures on Tuesday, Wednesday, and Saturday. Extended weekends available. Origin/Destination reversible. No Christmas dates available.
JetBlue’s “Basic” fares only allow a small personal item (17 x 13 x 8 inches), like a Jansport SuperBreak backpack without a fee. A regular sized carry-on bag will incur a bag fee. To avoid bag fees, consider using a credit card with the “first free checked bag” perk.
