Delta has round-trip flights from Dallas (DFW) to New York City (LGA) for $131, NONSTOP. Flights March to November. Weekends available. Origin/Destination reversible.
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.
Note: We feel that this deal will be a better match for most people than the Spirit deal that was mentioned earlier today, despite costing a bit more. Delta has more weekend dates available, lower fees, and a better schedule overall.
