Southwest has round-trip flights from Houston (HOU) to Denver, Chicago, Baltimore, or Atlanta (DEN, MDW, BWI, ATL) for $98, NONSTOP. $49 each-way. Flights from October to February. Most availability starts in November. Origin/Destination reversible. No Holidays. Mostly weekdays.
Note: United, Spirit, and Frontier may have fee encumbered “Basic Economy” fares available for a bit less. Keep in mind that those “cheaper” fares are often more expensive once you factor in bag fees.
Note: You can save an additional $125 if you book your Flight+Hotel together as a package on Southwest Vacations and use the 125DOM19 coupon-code. Before you commit, always compare the prices of the individual Flights and Hotel with other hotel booking sites like Hotels.com.
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.
