George Bush Intercontinental Airport continues to undergo major changes in 2026 as Houston moves forward with terminal modernization, new passenger facilities, expanded international service and additional infrastructure projects.
The airport remains one of Houston’s primary aviation gateways and a major hub for United Airlines. Travelers are currently seeing a mix of active construction and newly completed improvements, making it important to check terminal information before every trip.
The most significant project remains the redevelopment of Terminal B. Work is progressing toward a planned fall 2026 completion, while other parts of the airport have already received upgraded facilities.
At the same time, international connectivity has expanded. United restored daily nonstop service between Houston and Caracas on August 11, giving travelers another direct option between Texas and Venezuela.
Several smaller improvements are also changing the passenger experience. New seating, charging areas, renovated restrooms and upgraded airport services are being introduced as the larger redevelopment program continues.
Terminal B remains the biggest change for travelers
Terminal B is in the middle of one of the airport’s most significant transformations.
The redevelopment is replacing aging facilities with a modern terminal designed to accommodate United Airlines’ growing operations. The new Terminal B North Concourse covers about 765,000 square feet across three levels.
The project includes two new passenger concourses and 22 gates.
Construction has moved well beyond the early demolition and structural phases. Steel, glass, mechanical systems, flooring and interior finishes are now part of the visible construction activity.
The redevelopment is expected to provide passengers with a more modern check-in and departure experience once the new facilities open.
For now, however, travelers should not expect the finished Terminal B experience.
The Terminal B lobby remains closed during construction. United passengers who previously relied on that lobby for check-in and security processing need to follow the current airport instructions for their trip.
The temporary arrangements are especially important for passengers who have not traveled through the airport recently.
Terminal B construction is approaching its final phase
The redevelopment has been underway for several years and represents a major investment in the airport’s future.
The new concourses are being designed around improved passenger movement. Larger spaces and updated systems are intended to make it easier to process travelers while supporting United’s expanding schedule.
The project is also closely connected with United’s broader modernization plans at its Houston hub.
The planned fall 2026 completion is one of the most closely watched milestones at the airport.
Once the new facilities become available, passengers should see substantial differences from the older Terminal B configuration.
The changes are expected to include updated passenger areas, new concessions, improved circulation and modern airline facilities.
The airport has continued operating throughout the construction process. That approach allows United to maintain its Houston network while crews complete the new facilities.
Travelers should check their terminal before arriving
Construction makes terminal planning more important than usual.
A passenger may know that a flight operates from Terminal B but still need to use another location for part of the airport process.
This is particularly relevant to United travelers because check-in arrangements have changed during the redevelopment.
Passengers should check their airline information before leaving home and allow additional time if they need to move between terminals.
The airport’s internal transportation system connects the terminal complex. The underground subway operates between the terminals, while the Skyway provides an elevated connection inside the airport.
These systems are especially useful when passengers need to move between terminals without leaving the airport complex.
Travelers should also pay attention to airport signs because construction areas and passenger routes can change as work advances.
Terminal E has entered a new stage
Terminal E is another major part of the airport’s recent transformation.
The terminal became fully operational ahead of the 2026 summer travel period. The transition involved international airlines that previously operated from Terminal D.
The completed work has strengthened the airport’s international passenger facilities and improved the way international travelers move through the complex.
Terminal E now carries the name Sheila Jackson Lee Terminal E following a dedication in 2026 honoring the late Houston congresswoman.
The terminal plays an important role in the airport’s international operations.
Thousands of international passengers use the facility each day, making its completion a significant development for Houston’s global air connections.
The transition also arrived at an important time because Houston experienced increased international travel demand during the 2026 summer season.
International service is expanding again
International flights remain an important part of the airport’s role.
One of the newest developments is the return of nonstop service between Houston and Caracas.
United began daily nonstop flights on August 11, 2026, using Boeing 737 MAX 8 aircraft.
The route reconnects Houston with Venezuela after United had suspended service between the United States and Venezuela in 2017.
The restored route gives passengers another nonstop option for travel between the Houston region and Caracas.
Houston’s location also makes the airport an important connecting point for travelers heading throughout Latin America and the Caribbean.
United operates a large international network from the Houston hub, making the airport particularly important for passengers traveling beyond Texas.
Passenger amenities continue to receive upgrades
Not every airport improvement involves a major terminal construction project.
Some of the most noticeable changes for passengers involve seating, charging stations and restrooms.
New seating was added near Gates A14 and A15 in Terminal A during 2026. The improvements increased seating capacity in that area and included workstations, group seating and charging access.
These additions address a simple but important passenger need.
Long waits between flights can make comfortable seating and convenient charging particularly valuable.
The airport is also continuing a restroom renovation program.
Renovated facilities are being introduced in several terminal areas as part of a broader improvement effort covering both major Houston airports.
The projects include updated fixtures, improved lighting, accessibility improvements and refreshed passenger areas.
These smaller upgrades are taking place alongside the much larger Terminal B redevelopment.
Retail and dining options continue to change
The airport’s passenger experience is also evolving through new restaurants and retail improvements.
One notable addition in 2026 is Taste of Gold, an airport restaurant concept associated with Houston native and Olympic gold medalist Simone Biles.
The opening adds another recognizable Houston connection to the airport’s food and beverage lineup.
Retail improvements are also continuing.
A Pandora store near Gate D7 in Terminal D is scheduled for a substantial renovation beginning in August 2026. The project is expected to continue into November.
The work reflects the broader effort to refresh commercial areas throughout the airport.
Passengers can therefore expect some individual shops and food locations to change during construction, even when the surrounding terminal remains open.
Parking rules have changed
Parking is another issue travelers should consider before arriving.
The airport changed its parking procedures in 2026, including new requirements affecting ecopark2.
Ecopark2 became reservation-only on June 1.
The airport has also indicated that some garage access can become limited to travelers with reservations once capacity reaches a specified level.
That makes advance planning more important during busy travel periods.
Passengers who intend to park at the airport should check current parking availability before starting their journey.
Economy parking remains an option for travelers seeking longer-term parking, while terminal garages provide closer access to the passenger facilities.
Shuttle services connect economy parking areas with the terminals.
Travelers should also allow time for parking shuttles when calculating their arrival schedule.
Federal funding is supporting additional improvements
The modernization effort extends beyond terminal construction.
Houston’s airports received more than $126 million in federal aviation grants during fiscal year 2026.
Several projects connected with the airport are benefiting from the funding.
The work includes infrastructure improvements involving the airport’s Skyway, airfield drainage and heating and cooling systems in Terminal D.
These projects may not attract the same attention as a new terminal, but they are important for maintaining airport operations.
Reliable infrastructure becomes increasingly important as passenger numbers and flight activity grow.
The additional investment also demonstrates that airport modernization involves more than passenger-facing construction.
The airport continues preparing for future passenger demand
The current projects are designed with long-term growth in mind.
The airport has handled tens of millions of passengers in recent years, and United continues to use Houston as one of its largest hubs.
That combination creates pressure on gates, security areas, baggage systems, roadways and passenger facilities.
Terminal B is intended to address some of those future needs.
The airport is also improving its operational coordination.
An integrated coordination center brings together airport operations, security personnel, gate control, maintenance dispatch and terminal operations.
Centralizing these functions can help airport teams respond more quickly when operational problems occur.
The system is particularly useful at a large airport where a problem in one area can affect passengers in several terminals.
Current airport operations remain active
Despite the construction activity, normal commercial operations continue.
The airport has not closed because of the Terminal B redevelopment.
Flights continue to operate from the airport’s multiple terminals, while construction crews work around active passenger areas.
That distinction matters because travelers sometimes mistake construction closures for airport-wide shutdowns.
The current situation is different.
Specific facilities have been closed or relocated, but the airport remains operational.
Passengers should therefore focus on their individual airline, terminal and gate information rather than assuming that construction affects every part of the airport.
Weather can still affect flights
Houston’s summer weather remains another potential factor for travelers.
High temperatures are common during August, while thunderstorms can develop quickly during the warmer months.
Severe weather can create delays even when the airport itself remains open.
Strong winds, lightning, heavy rainfall and thunderstorms can affect aircraft movements and ground operations.
Passengers should check their flight status before leaving for the airport, especially when severe weather is forecast.
Travelers should also avoid assuming that a flight will operate on its normal schedule simply because the airport is open.
Airlines make individual decisions about delays, cancellations and schedule changes.
What travelers should expect during the remainder of 2026
The next major milestone is the completion of Terminal B.
The project remains targeted for fall 2026, making the coming months particularly important for passengers who regularly use the airport.
As construction progresses, passenger routes and temporary arrangements can change.
The opening of the new facilities should eventually reduce some of the inconvenience associated with the current construction period.
Terminal E’s completed transition already represents another major step in the airport’s modernization program.
Meanwhile, infrastructure projects, passenger-area upgrades and commercial renovations continue throughout the complex.
The result is an airport undergoing several changes at the same time.
Key changes travelers should know
For passengers planning a trip, the most important current developments include:
- Terminal B remains under major redevelopment.
- The Terminal B lobby remains closed during construction.
- The new Terminal B facilities are targeted for fall 2026 completion.
- Terminal E is fully operational.
- Terminal E has been dedicated as Sheila Jackson Lee Terminal E.
- United has restored daily nonstop Houston-Caracas service.
- Ecopark2 requires reservations.
- New seating and charging facilities have been added in Terminal A.
- Restroom renovations continue in multiple areas.
- Federal funding is supporting additional infrastructure improvements.
- Retail and dining facilities continue to receive upgrades.
These changes mean that passengers should plan each trip using the latest airport and airline information.
What the latest airport developments mean for passengers
The airport is entering an important period as major construction moves toward completion.
Terminal B is the biggest project still affecting travelers directly. Its eventual opening should mark a major change in the passenger experience.
Terminal E’s transition, meanwhile, has already strengthened international operations.
The return of nonstop Caracas service adds another international connection, while ongoing facility improvements are designed to make the airport more comfortable and efficient.
For travelers, the most practical lesson is simple: do not rely on an old terminal routine.
Check the latest flight information, confirm where to check in, review parking requirements and allow enough time to navigate the airport.
The construction is temporary, but the infrastructure being created is intended to serve Houston travelers for years.
