Delta has round-trip flights from Dallas (DFW) to Santo Domingo (SDQ) for $337 with a connection. Flights May, June, August, September, October, November, December, January, February, and March. Weekends available.
Note: Avoid routes that require ground transportation between LGA and JFK.
Note: Avoid Spirit “deals” on this route. They only have 28-inches of seat space and charge a fee for carry-on, snacks, and seat selection.
Note: Carry-on bag is allowed for free on Delta. You can avoid paying for seat selection by accepting the randomly assigned seat at the gate.
