Southwest has round-trip flights from Dallas (DAL) Atlanta (ATL) for $90 or Baltimore (BWI) for $142, NONSTOP. Flights mostly from January to March. Origin/Destination reversible. No Holidays.
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 $100 if you book your Flight+Hotel together as a package on Southwest Vacations and use the HOLIDAYDOM coupon-code. Before you commit, always compare the prices of the individual Flights and Hotel with other hotel booking sites like Tripadvisor and Expedia.
