The lounge opens Thursday at the airport's Terminal B, which is being rebuilt with 22 gates for mainline aircraft. George Bush Intercontinental handles more than 500 departures a day and serves as United's main connecting hub for flights to and from Latin America.
The new club seats up to 800 people and features an outdoor terrace for plane-spotting, two full-service bars and buffets. It is part of United's broader $2.6 billion investment at the terminal, which the airline says reflects growing demand for premium travel spaces.
The move comes as United's rivals expand their own lounge offerings. American Airlines said earlier this month it is planning its largest ever lounge at its Charlotte Douglas International Airport hub in North Carolina. Delta Air Lines has expanded both its Delta Sky Clubs and its top-tier Delta One Lounges. Southwest Airlines is building its first ever network of lounges, tied to its credit card partner Chase, and last week unveiled mock-ups of the clubs, which it is calling Icon. JetBlue Airways opened lounges in New York and Boston within the past year.
The trend points to airlines channelling more money into larger spaces to serve the growing ranks of elite frequent flyers, co-branded credit card holders and customers willing to pay more to fly.
