United and Southwest have round-trip flights from Houston (IAH) to St. Louis, Savannah, Columbus, San Jose, San Diego, Denver, or Atlanta (STL. SAV, CMH, SJC, SAN, DEN, ATL) for $117-$179, NONSTOP. Flights October to March. Origin/Destination reversible.

United has recently matched the Southwest fare sale that we mentioned a few days ago. This is a small subset of total fares on sale, see the full list in the Domestic Airfare post.

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.

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

Do a search on Tripadvisor to find guides, tours, restaurants, attractions, and cool things to do. It’s a good resource to use for planning your day-to-day itinerary while on vacation.

We post new flight deals often! You can check out our other deals by returning to the Front Page of our website: escapehouston.com (linked).

When you are ready to book your flight or hotel, please use the links on our site to begin your booking process so we receive credit for the referral.

  • 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.
