The Beehive as it came to be known, was a circular building allowed aircraft to park around its entire circumference, reducing walking distances while maximizing gate positions.  It reflected early thinking about efficiency and spatial organization, ideas that would later become central to airport design.

What’s remarkable about this period is how airports functioned as social destinations too. In 1939, New York’s La Guardia Airport attracted nearly 250,000 visitors each month—far more than the number of actual passengers. Families dressed up to watch planes arrive and depart from observation decks, ate at airport restaurants, and spent their weekends experiencing the magic of aviation. Airports were probably places where the future felt tangible and accessible.

Form Follows Function

The 1960s brought a paradigm shift with the arrival of jet aircraft. Passenger numbers increased, travel distances expanded, and airports became national gateways. Functionality and cost efficiency became important. Amsterdam Schiphol Terminal, completed in 1967, offered a thoughtful approach. Designed to expand in modular fashion, the terminal could grow by adding box-like sections as needed. This flexibility proved remarkably successful. The original terminal remains at the heart of Schiphol even today. San Francisco International Airport played a key role in reshaping the passenger experience. Among the first airports to introduce jet bridges, SFO eliminated the need for apron boarding, allowing passengers to move directly from terminal to aircraft in a controlled, weather-protected environment.

Even as this happened, there were moments when architectural design took center stage. Eero Saarinen’s TWA Flight Center at JFK. Its sweeping concrete shells, dramatic interiors, and sculptural form embodied the optimism of the Jet Age. The terminal was designed to make air travel feel futuristic, elegant, and aspirational.

Architectural Expression

From the 1980s the design space saw dramatic transformation as concrete boxes gave way to glass designs. Architects embraced natural light and transparency, creating terminals that felt open and welcoming. The designs incorporated concepts of “light” and “air,” using advanced engineering to build soaring glass structures that challenged the boundaries between inside and outside.
This shift wasn’t merely aesthetic. Glass terminals improved passenger experience by creating better wayfinding through natural light, reducing energy costs through daylighting, and providing emotional uplift during what could be stressful journeys.
In parallel, there was further experimentation with forms, with few iconic terminals like Paris Charles de Gaulle Terminal 1 and Heathrow’s early terminals. While forms were innovative, they were frequently criticized for disorienting circulation for passengers. Chicago O’Hare International Airport developed by SOM, had long concourses, had a structural grid pattern and a deliberately neutral design.

Security Reshapes the Terminal

The events of 9/11 permanently altered airport terminal planning. Security screening moved from the periphery to the centre of the passenger journey, reorganising circulation, space allocation, and architectural priorities. Architects attempted to counterbalance the rigidity of security processes through daylight, large volumes, and improved wayfinding, as seen in Richard Rogers’- Heathrow Terminal 5, where a vast, column-free hall, exposed steel structure, and abundant daylight created legibility and calm. Architecture became a psychological buffer, mitigating the stress of surveillance-heavy environments.

Architect Renzo Piano can also be credited with the influence, through his emphasis on lightness, human scale, and clarity, principles adopted by many terminal architects.

Modern Masterpieces

Today’s airport terminals place passenger experience at the forefront and balance the architectural ambition with the help of technology. Buildings like Beijing Daxing Airport designed by Zaha Hadid, Jewel Changi by Moshe Safdie, and many more function as cultural gateways that express national identity and technological prowess.

Looking Forward

From grass fields observation stands to modern efficient designs, airport terminals have evolved dramatically over the past century. Each generation of designers learning and adapting solutions to new technologies and needs. A terminal building is not about solving immediate problems but anticipating the future also, because these structures outlive generations.

The next time you walk through an airport terminal, take a moment to look around. You’re standing in a building type that didn’t exist 100 years ago, shaped by a century of experimentation, failure, and innovation.
