United has round-trip flights from Dallas (DFW) to Montego Bay (MBJ) for $350-$357 with a connection. If you apply the Hopper -$40 off coupon, the cost of the round-trip can get as low as $310. Flights July, August, September, and January. Very few weekends available. Origin/Destination reversible.
United’s “Basic Economy” fares do not allow for a free carry-on bag. Only a personal item (like a small laptop bag) is free. Seats are randomly assigned for free prior to boarding.
