Southwest has round-trip flights from Dallas (DAL) to New York (LGA) or Tampa (TPA) for $132, NONSTOP. Flights mostly from January to March. Origin/Destination reversible. No Holidays. Weekends available.
Note: Southwest doesn’t charge a change-fee, so if you already booked this flight, but paid more, you should be able to re-book at the lower price and get the difference paid back to you in the form of a travel-voucher.
Note: You can save an additional $75 if you book your Flight+Hotel together as a package on Southwest Vacations and use the YEARENDDOM coupon-code. Before you commit, always compare the prices of the individual Flights and Hotel with other hotel booking sites like Tripadvisor and Expedia.
