The last time many South Africans hugged loved ones at an airport gate without a boarding pass was more than two decades ago. Today, access to terminals and the zones beyond security is tightly controlled — a gradual shift driven by a string of attacks and plots that exposed weaknesses in how passengers and luggage were screened.
From open gates to ticket-only access
In earlier decades, airport security was operated by private contractors hired by airlines and was far less intrusive than it is now. Full-sized toiletries and everyday items flown in carry-on bags routinely passed through checkpoints. Relatives and friends could accompany travellers to boarding areas and say farewell at the gate.
That changed layer by layer as different incidents revealed new vulnerabilities — from bombs hidden in checked luggage to hijackers willing to turn aircraft into weapons. The system passengers encounter today was built in response to those threats, rather than being planned all at once.
"Attacks on aviation have an impact much greater than attacks on anything else because aviation commands the attention of the world as the thing that links the world," said Mary Schiavo, an aviation disaster attorney.
The most transformative single day for modern air travel security was 11 September 2001, when 19 al-Qaida hijackers took control of four commercial aircraft and used them to attack high-profile targets. Two planes hit New York’s World Trade Center, one struck the Pentagon and another crashed in Pennsylvania. Before that, authorities generally assumed hijackers sought negotiation rather than deliberate crashes.
Immediate changes after 11 September
U.S. authorities moved quickly in the aftermath of the attacks. The Federal Aviation Administration (FAA) introduced measures that helped make today’s airport experience familiar to travellers worldwide:
- Restricted gate access — airports limited the areas around departure gates to ticketed passengers only.
- Prohibition of certain items — knives and box cutters were banned from carry-on luggage after hijackers used such items to threaten and harm passengers.
These and later reforms were prompted by a realisation that some assumptions about hijacker behaviour were no longer valid — authorities had to plan for suicide attackers willing to use aircraft as weapons.
How past attacks still shape travel rituals
The cumulative effect of security upgrades is visible every time we pass through an airport. Farewells happen at curbside, in cafés or at departure lounges before security. Families, who once had a few private minutes at the gate, now exchange final hugs earlier or wait at arrivals to welcome travellers back.
Some aspects of modern screening — such as limits on liquids in carry-on bags and thorough security checks — were introduced later, as other attempts and plots exposed new methods of concealing threats. The security framework in place today reflects an evolving patchwork of responses to past incidents rather than a single central design.
| Event | Security outcome (as reported) |
|---|---|
| Earlier decades | Private contractors managed checkpoints; more relaxed carry-on rules; easier gate access |
| Bombings and plots (including Pan Am Flight 103 era) | Layered security and new screening attention to checked luggage |
| 11 September 2001 | Restricted gate access to ticketed passengers; ban on knives/box cutters from carry-ons; broader focus on suicide hijackings |
What travellers should know
Understanding why gates are off-limits to non-travellers helps explain why airports look and feel different from memories of the past. The changes were not only about preventing theft or minor incidents — they were reactions to events that reshaped global attention on aviation safety.
- If you’re seeing someone off, plan to meet them well before security checkpoints.
- Expect limits on items taken in carry-on baggage and follow airline and airport advisories.
- Remember that security measures evolve in response to new threats — some procedures you find inconvenient are designed to prevent much larger harms.
As the world marks anniversaries of major attacks, the way we travel becomes part of that history. Those brief, emotional moments at the gate are rarer now, but the changes were born of hard lessons about the risks facing civil aviation — and a choice to prioritise safety in shared spaces.
