Houston airport powers up new gaming lounge for bored and weary travelers

game on and wheels down

Local gamers now have a new option to while away those flight delays and passenger pickup waits at Hobby Airport.

Houston's William P. Hobby Airport is now one the first airports in the country to offer what's dubbed as the "ultimate gaming experience for travelers." The airport has launched a premium video game lounge inside the international terminal called Gameway.

That means weary, bored, or early travelers can chill in the lounge and plug into15 top-of-the-line, luxury gaming stations: six Xbox stations, five Playstation stations, four PC stations, all with the newest games on each platform. Aficionados will surely appreciate the Razer's Iskur Gaming Chairs and Kraken Headsets, along with dedicated high speed internet at each PC station.

The Gameway lounge pays homage to gaming characters, with wall accents that hark to motherboard circuits Crucial for any real gamer: plenty of sweet and savory snacks are available for purchase to fuel up on those fantasy, battle, or sporting endeavors. As for the gaming console stations, players can expect high definition screens, comfortable seating, and plenty of space for belongings.

This gaming addition comes just in time for the holiday rush, when travelers can expect long lines, delays, and are already planning for extended time for trips. As CultureMap previously reported, Hobby will see a big boost in travelers this season — the largest since 2019. Now, those on a long journey can plug in, decompress, and venture on virtual journeys of their own.

Texan travelers may be familiar with Gameway; the company opened its first two locations at Dallas Fort-Worth Airport. The buzzy lounge an industry wave of acclaim: Gameway was awarded Best Traveler Amenity in 2019 at the ACI-NA Awards and in 2020, voted “Most Innovative Customer Experience” at the Airport Experience Traveler Awards, per press materials.

Two new locations followed in 2021: LAX Terminal 6 and Charlotte Douglas International Airport. The first of Gameway's Ultra lounge brand opened in September at Delta's Terminal 3 in LAX.

Gaming culture is a way of life in the Bayou City , which hosts Comicpalooza, the largest pop culture festival in Texas, and is home to several e-sports teams, including the pro esports squad, the Houston Outlaws.

“Gameway is the real reason to get to the airport early,” said Co-Founder Jordan Walbridge in a statement. “Our mission is to upgrade the typical wait-at-the-gate experience with a new stimulating, entertaining option for travelers of all ages.”

Here's guessing Hobby might just see an increase in missed or late flight arrivals — as travelers simply must beat those big bosses, solve puzzles, or win sports matches in the lounge.
