Tribute in Light. Photo: Mariusz Lopusiewicz / Shutterstock.com On September 11, 2001, four passenger planes were turned into weapons, the Twin Towers collapsed into the heart of Manhattan, the Pentagon was attacked, and another plane crashed in Pennsylvania.
Thousands of people were killed, the United States entered a new era of terrorism and war, and the world of aviation and tourism suffered one of the worst blows in its history.
The skies closed, planes were grounded, airports emptied, and travelers around the world asked themselves for the first time whether "flying is still the safest and most natural way to get from place to place," as the saying went. The echoes of that black morning didn't just stay in the United States. They reached every airport, every airline, and virtually everyone who has boarded a plane since.
Until September 11, it was possible to get to the airport almost to the boarding gate, see passengers off and say goodbye to them there. After the attacks, airports became much more secure spaces. The US Transportation Security Administration (TSA) was established, passenger and luggage screening was significantly expanded, reinforced doors were added to cockpits, and a long list of new security procedures was introduced.

The economic damage to the airline industry was enormous. American airline passenger revenue fell from $105.3 billion in 2000 to just $92 billion in 2001. In the United States, the industry recorded a loss of about $8 billion that year, and the losses continued in subsequent years. Globally, airline revenue fell from $328.5 billion in 2000 to $307.5 billion in 2001.

For some airlines, September 11 marked the beginning of a long period of dealing with low demand, falling prices and higher security costs.
Some airlines did not survive. In the United States, US Airways and United fell into a deep financial crisis and were later forced to file for bankruptcy protection. American Airlines also suffered heavy losses. Smaller companies collapsed in the immediate aftermath of the crisis, including Midway Airlines and the legendary TWA, which was already in dire financial straits. American Airlines had acquired the company a few months earlier, and its disappearance from the market symbolized the industry's dramatic shift.
The fear of flying did not disappear in a matter of days. A study by IATA found that in the four to five months following the attacks, demand for domestic flights in the United States fell by more than 31%. Even after the initial panic subsided, demand remained significantly lower than what would have been expected had the attacks not occurred.

In 2002, about 5.1 million tourists from around the world arrived in the city, down about 25% from 2000. This meant not only fewer tourists, but also a direct hit to hotels, restaurants, attractions, shops, and transportation.

Since the most devastating attack in history, flying is not just about getting from one point to another, as it involves checks, identification, scans and security preparations that have become an integral part of the journey.
25 years later, the world of aviation has grown again and even reached new heights, but the passenger of 2026 still passes through an airport that was born, in large part, from the trauma of that black morning of September 11, 2001.
