Athens International Airport is embarking on one of Europe’s most ambitious aviation infrastructure projects, a comprehensive €1.3 billion redesign and expansion that will transform Greece’s largest airport into a modern gateway capable of handling up to 40 million passengers annually by 2032. This undertaking is a strategic response to unprecedented growth, with the airport recording 31.85 million passengers in 2024, marking a 13.1% increase from the previous year. The project encompasses not only substantial physical expansion but also integrates sustainable design principles and innovative architectural concepts, aiming to blend Athens’ cultural heritage with contemporary passenger needs.
The expansion, led by the international Anemos consortium (including Grimshaw, Haptic, and K-Studio), introduces design elements such as Mediterranean gardens within oculus atriums, terraced seating areas, and extensive natural light throughout the terminal complex. The transformation is being implemented while maintaining full operational capacity, a logistical challenge that underscores the project’s sophistication and the airport’s critical importance to Greece’s tourism-dependent economy.
Historical Background and Current Operational Context
Athens International Airport Eleftherios Venizelos was designed and built by Hochtief, opening in 2001, initially to serve the Athens 2004 Summer Olympics. Located 20 kilometers from the city center, it is Greece’s largest aviation facility and the primary entry point for the country’s thriving tourism sector. The airport operates under a concession agreement, extended in 2019, currently running until June 2046.
The airport’s dual-till regulatory structure classifies activities into “air” and “non-air,” with about 78% of revenues from regulated activities. Its catchment area covers approximately 6 million people, extending at least 250 kilometers from Athens. Athens Airport has shown remarkable resilience, especially post-pandemic, and is now connected to 157 destinations in 55 countries, served by 68 carriers. It is ranked as the 9th most connected hub in Europe (OAG 2024).
The current infrastructure was designed for 26 million passengers annually, a threshold exceeded in recent years due to robust tourism recovery and increased connectivity. In 2024, the airport handled 31.9 million passengers, a 13.1% increase over 2023, placing Athens among the fastest-growing European airports.

DFW Airport Opens First Four Terminal A Gates in 2026
DFW Airport opens gates A10-A15 for American Airlines as part of its $12 billion DFW Forward capital improvement program.
Dallas Fort Worth International Airport (DFW) and American Airlines have commenced operations at the first four gates of the Terminal A Pier Expansion, marking a tangible milestone in the airport’s $12 billion capital improvement program.
Announced in a press release on October 21, 2026, the opening of gates A10, A11, A13, and A15 follows a multi-year construction effort that utilized prefabricated modular building techniques to minimize disruption at the world’s second-busiest airport. American Airlines began operating flights from the new gates in mid-October 2026.
Modular construction minimizes airfield disruption
The Terminal A project adds 140,000 square feet to the existing footprint and will ultimately feature 10 gates, comprising five rebuilt and five net-new positions. The remaining six gates are expected to open to travelers during the 2026 winter holiday season.
To execute the expansion without shutting down active terminal areas, contractors utilized an industry-first modular construction method. In 2024, crews transported seven pre-built modules over 1.5 miles across the active airfield to the Terminal A project site. Prior to transport, 65% of the Mechanical Electrical Plumbing (MEP) work was already completed on the modules.
The expanded pier features wider thoroughfares, taller ceilings, brighter windows, intuitive wayfinding, new concessions, and updated restrooms designed to accommodate higher passenger volumes.
The $12 billion DFW Forward initiative
The Terminal A Pier Expansion is a central component of DFW Forward, a historic $12 billion capital improvement program designed to modernize aging facilities and accommodate future passenger growth at the North Texas hub.
The Terminal A expansion follows earlier 2026 milestones within the DFW Forward program. This includes the opening of nine new and rebuilt gates in Terminal C, which also utilized prefabricated modular construction transported across the airfield.
Airports globally are increasingly turning to modular and prefabricated construction to execute major capital projects. DFW’s deployment of this method for both the Terminal A and Terminal C expansions sets a precedent for large-scale infrastructure upgrades in constrained, high-traffic aviation environments.
American Airlines’ footprint in North Texas
DFW serves as the largest hub for American Airlines, which is headquartered in nearby Fort Worth, Texas. The carrier accounts for approximately 82% of the airport’s commercial passenger traffic, operating over 900 peak-day flights to 230 destinations.
The scale of the operation has a substantial regional impact. According to an August 2026 study by Texas Christian University (TCU), American Airlines’ DFW hub supports approximately $70 billion in annual economic output and sustains 350,000 jobs across the North America region.
The infrastructure upgrades are necessary to support this volume. DFW handled 85.7 million passengers in 2025, ranking it as the second-busiest airport in the world by passenger traffic and the third-busiest by aircraft movements.
AirPro News analysis
We view DFW’s successful deployment of modular construction across both Terminal A and Terminal C as a blueprint for other constrained mega-hubs. As passenger volumes push past 2019 peaks, operators can no longer afford to take large sections of terminal space offline for years at a time. By shifting the majority of the mechanical and electrical work off-site, DFW has demonstrated that capacity expansion and continuous hub operations are not mutually exclusive.

United Airlines Opens Terminal B North Concourse at IAH
United Airlines opens a 765,000-sq-ft concourse at IAH with 22 gates, completing a $2.6B terminal overhaul.
United Airlines Holdings, Inc. (UAL) has officially opened its new 765,000-square-foot Terminal B North Concourse at George Bush Intercontinental Airport (IAH), completing the centerpiece of a $2.6 billion infrastructure overhaul.
Previewed on October 21, 2026, and opened to the public on October 22, 2026, the facility introduces 22 mainline gates and the largest United Club in the Americas. According to a company press release, the expansion increases the carrier’s peak travel date capacity in Houston by 40% compared to 2023.
Upgraded passenger facilities and mainline capacity
The new three-level concourse replaces outdated infrastructure with 22 mainline gates, all equipped with jet bridges to accommodate larger aircraft. The architectural and operational upgrades are designed to streamline passenger flow and reduce congestion during peak departure banks.
A major focal point of the development is the 54,000-square-foot United Club. With a seating capacity of 800, it is now the largest lounge operated by any airline in the Americas. The terminal also incorporates local Houston dining brands, including B&B Butchers & Restaurant, Rosie Cannonball, Pizaro’s Pizza, Blood Bros. BBQ, Katz Coffee, and Blue Bell Creameries. The public spaces feature 10 major art installations and 11 sets of restrooms.
“I want our customers to start their vacation the minute they show up at the airport and Terminal B North sets a new standard for facilities across the country,” said United Airlines CEO Scott Kirby.
Funding and execution of the Terminal B Transformation Program
The opening of the North Concourse represents the most significant milestone in the broader Terminal B Transformation Program. The original Terminal B opened in 1969, and its infrastructure had become undersized for modern mainline aircraft operations and current passenger volumes.
United Airlines and the Houston Airport System (HAS) formally announced the $2.6 billion modernization initiative on November 7, 2023. The project secured critical municipal backing on March 6, 2024, when the Houston City Council voted to allocate $150 million toward the city’s portion of the expansion under a Memorandum of Agreement.
Once subsequent improvements to the South Concourse are completed, United will operate a total of 48 gates across Terminal B.
Kirby emphasized that the airline’s strategy extends beyond fleet modernization. “Houston is great example of our focus on the overall customer experience,” Kirby stated. “Yes, we’re investing in new aircraft, products and technology here, but we’re also focused on improving the infrastructure, building new concourses, baggage systems and training and maintenance facilities for our employees.”
Strategic growth at the Houston hub
United Airlines is the largest carrier globally as measured by available seat miles, and Houston serves as one of its primary domestic and international hubs. The airline is the largest operator at IAH, managing more than 500 daily departures and employing over 14,000 people in the region.
The completion of the North Concourse builds on a sustained period of capital expenditure by the carrier in Texas. Since 2015, United has invested $3.5 billion into its facilities and operations at IAH.
The immediate operational impact of the new concourse is a 40% increase in the number of passengers the airline can accommodate on peak travel dates in 2026, alleviating previous capacity constraints at the hub and supporting future schedule growth.

OKC Airport Plans 25-Year Expansion to 20 Million Passengers
Will Rogers International Airport unveils a phased master plan to quadruple capacity to 20 million annual passengers by 2050.
Oklahoma City officials have unveiled a 25-year master plan for Will Rogers International Airport (OKC) designed to quadruple annual passenger capacity to 20 million. The phased expansion aims to accommodate rapid regional growth and prepare the facility for international traffic ahead of the 2028 Summer Olympics.
Announced on October 13 in a city press release, the “Cleared for Takeoff” initiative outlines a demand-driven approach to infrastructure investment. Rather than relying on strict calendar dates, major construction phases will be triggered by specific passenger volume milestones, ensuring the airport scales its landside and airside facilities in step with actual utilization.
Phased infrastructure triggers
Will Rogers International Airport currently serves a baseline of 4.6 million passengers annually. The new master plan establishes a roadmap to handle future demand through three primary expansion phases.
Phase 1 will activate when annual passenger traffic approaches the 6 million mark. This initial stage focuses heavily on landside improvements, including the addition of 1,538 new parking spaces housed within a five-level structure. Phase 2 will commence when the airport reaches 8 million annual passengers. This stage includes an approximate 550-foot extension of the curbside frontage and expands the terminal to support between 24 and 26 gates. Notably, this phase incorporates at least one designated position for widebody aircraft.
The fully realized Phase 3 vision scales the facility to a total of 40 gates and widens the curbside layout to six lanes. Director of Airports Jeff Mulder stated in the release that the plan outlines the trajectory for long-term growth.
“This is a monumental step toward balancing our landside facilities with airside terminal capacity, elevating passenger processing, and ensuring Oklahoma City remains seamlessly connected to the global economy,” Mulder said.
Preparing for international traffic and LA28
The long-term expansion strategy follows a 25% increase in passenger traffic at the airport over the past decade, according to reporting by KGOU. Local leaders are prioritizing infrastructure to maintain momentum in air service development.
“We have to plan and prepare for that growth at our airport, because we never want to decline new air service due to inadequate infrastructure,” Oklahoma City Mayor David Holt told KGOU.
While the major terminal expansions are tied to future passenger milestones, several near-term upgrade projects are already underway. Terminal flooring upgrades began in September 2026, and a rehabilitation of Terminal Drive is scheduled to commence in mid-October 2026. The airport anticipates completing restroom renovations by December 2027, followed by the conclusion of the flooring upgrades in January 2028 and the Terminal Drive project in February 2028.
These immediate improvements align with Oklahoma City’s preparations to host the canoe slalom and softball events for the LA28 Olympic Games, scheduled for July 14 to 30, 2028. To support the anticipated influx of international visitors, the airport recently constructed a new customs area. This facility will process the airport’s first nonstop international flights, which are expected to launch in November 2026.
