Southwest and United have round-trip flights from Houston (HOU/IAH) to Baltimore (BWI) for $157-$170, NONSTOP. Flights September to January. Departures on Tuesday, Wednesday, and Saturday. Extended weekends available. Origin/Destination reversible.

United’s “Basic Economy” fares do not allow for a free carry-on bag. Only a personal item (like a small laptop bag) is free. Seats are randomly assigned for free prior to boarding.

The personal item size on United is smaller (9 x 10 x 17 inches) than Frontier or Spirit (8 x 13 x 18 inches).

If you use the United℠ Explorer Card, your first standard checked-bag for you and your companion is free, you get priority boarding, two United Club passes per year, and you get a 25% discount on inflight purchases on United-operated flights as a statement credit.

Use a card like the Southwest Rapid Rewards® Plus Credit Card to earn points towards a Companion Pass®. Companion Pass is the benefit that allows you to choose one person to fly with you, free of airline charges* every time you purchase or redeem points for a flight. *Companion Pass doesn’t cover taxes and fees.

Southwest Vacations usually has discounted package deals available that can save you more money. Package deals require than you book your flight + hotel together as a package, so it’s less flexible, but the package discount may be significantly cheaper than booking your flight and hotel separately.

You can usually save more money by booking your flight+hotel together as a package instead of separately.

  • Tips: Use Tripadvisor to create a Hotel “short list”. First, plug in your dates and destination. Then select “Sort by Traveler Ranked”. Finally, select the “Traveler Ranking” filter to show “only 4* and up”. Use this resulting “short list” of hotels to find the cheapest one with a high ranking.
  • Tips: Hotel rates for Weekend dates are usually higher than the rates for Sunday through Thursday. Tripadvisor has a color-coded date calendar, red when the average hotel price for that day is more expensive, green for less expensive. You can use this to get an overview of what dates in the month are at a discount.
  • Tips: Different booking websites will often have differing routes, prices, and availability. Before you finalize your purchase, do a quick check on BookingBuddy, Skyscanner, and Kayak to see if any other site or airline is offering a better deal.
