20 years later — 10 big 9/11 aviation changes


Some of us can remember what it was like before 9/11. Many of us cannot!


9/11 aviation changesMemories are fading. Today, we are starting to see teenagers coming into their own who have never known anything but the world of airport security and endless wars in the Middle East. We have 20 years of 9/11 aviation changes in place.

The numbers of airlines that used to be flying across the country and around the world have changed dramatically and the make-up of the world’s economy has changed enormously. Here are 10 important 9/11 aviation changes (from my US point of view) the world has seen since that fateful day.

Everyone from teens to adults who were alive remembers where they were on 9/11 when the Twin Towers came down.

Irritated by hotel resort fees?Most of us who were alive on 9.11.2001 remember exactly what we were doing when we heard that the twin towers had been hit by a plane. I was in my apartment in Boston, watching a morning show; which one, I forget. I thought it was a small plane, then a second plane hit. And, America knew this was more than a simple accident. Everyone watched with disbelief as the giant towers, one after the other, pancaked down in place, almost as if a planned demolition was taking place. It was, literally, breathtaking.

This weekend marks the 20th anniversary of the September 11th attacks – a sober milestone that takes on extra significance just days after the difficult U.S. withdrawal from Afghanistan. A new Ipsos poll with the Chicago Council on Global Affairs shows that two decades later, one in five Americans (21 percent) still rank it as one of the top life-changing events of the 21st century, topped only by the ongoing coronavirus pandemic (50 percent). It has the greatest lingering impact on Americans age 50 to 64 today – nearly one in three (29 percent) say it was the most personally impactful event in their lives.

Life, as far as travelers knew it, would never be the same.

For the country, that moment initiated a series of actions that shifted the tectonic plates of international relations. The repercussions are still obvious. And, headlines, like Syrian and Afghanistan refugees pouring into Europe and the US over the last weeks, all were spawned from that fateful day.

And, after reading through these 9/11 aviation changes, you will surprise yourself if you remembered how much plane travel is different from only 20 years ago.

9/11 aviation changes1. TSA came into being.

All Americans, for the first time in our history, were subjected to search, en masse. Now, will we be identified by our faces? Facial recognition seems to be a major privacy frontier even though we show it to everyone.

2. Full-body scanners.

We all know them. We all dislike them. No one really seems to know what they can and can’t reveal.

3. Pre-screening of travelers became the real domestic front against terrorism.

We found ourselves in the front lines battling airline terrorism. The terrorism watch list and a search of every passenger against such a list is the backbone of the security apparatus. Since the improvements to this list, no terrorists have been apprehended at airports in the US. This kind of multilevel screening almost makes the phalanx of security officers unnecessary, except for the lone madman or the forgetful among us.

4. TSA Pre-Check

This program now allows those enrolled in the system to move through security lines, “Just like in the old days, pre-9/11.” The cursory security checks serve as a fig leaf to provide a visible screening for the public. The real work is done behind the scenes.

9/11 aviation changes5. The airline world changed.

The economic consequences of changes in the travel and tourism world resulted in dramatic shifts within the airline world. U.S. Airways and America West merged in 2005; Delta and Northwest in 2008; United and Continental in 2010; Southwest acquired AirTran Airways in 2011; American and U.S. Airways in 2013. Today, four giant airlines control about 85 percent of the domestic traffic.

And, there were no ancillary fees. No checked baggage fees. No seat reservation fees. Now they are a bedrock of airline profits. There was no TARMAC delay rule. Passengers sat on the runways for hours. Today the limit is three for domestic flights and four for international flights.

6. Airline alliances came into focus as one of the most important 9/11 aviation changes.

Though the first airline alliance was created in the early 1990s between Northwest Airlines and KLM, the other alliances didn’t fall into place until just before 9/11. Since then, airline alliances have taken over something like 80 percent of the international aviation market. Three alliances — Oneworld, SkyTeam and Star Alliance — hold most of the airline world in their folds.

7. Open Skies treaties created a boom in international travel.

Once countries allowed airlines the freedom to set their own schedules and plan their own routes back and forth to the US, the world of international travel began to grow enormously.

8. The Middle East and Afghanistan are in turmoil.

Our military actions in both countries uprooted the devil we knew and unleashed new demons. The subsequent “Arab spring” released years of pent-up social and religious pressures. Stable, if dictatorial, governments that provided basic services for their populations were overthrown, but without any plans for what was to come next other than “freedom.” This lack of any steady, strong, organized government, has refugee camps overflowing and the stream of those looking for a better life on the move to more stable countries.

9. Africa and South Asia are home to the world’s fastest-growing middle class.

The growth of the middle class in southern Asia and sub-Sahara Africa has moved the economic center (and thus the crossroads) of the world from being between Europe and the US to somewhere over the Middle East.

This, together with the rise of China’s economic machine, has giant consequences for airline travel and trade. None of the most heavily traveled airline routes are in the US or Europe. They are all in the Far East. The world’s busiest international airport is now in Dubai. The US is no longer the center of the economic or transport world.

10. The iPhone didn’t exist.

In early 2007 Apple announced the very first iPhone. Designed to “reinvent the phone,” it has reinvented our lives. Today, the iPhone forces a reinvention of how we travel, purchase travel, plan for travel and communicate during travel.
