Airports have changed enormously over the past two decades, but some travelers never quite got the memo. Grandpa still shows up with the same jokes, the same confident opinions about “the good old days” of flying, and the same knack for saying exactly the wrong thing at exactly the wrong checkpoint. It is not malice, just habit, and a worldview shaped by a time when a pocketknife in carry-on luggage was barely worth a second glance.
What follows is a lighthearted look at the classic lines that tend to slip out of grandfathers at security checkpoints, and why each one tends to make a Transportation Security Administration officer’s eyebrow twitch just a little.
1. “I’ve been flying since before any of this nonsense started”
This line usually comes out the moment a TSA officer asks grandpa to remove his belt or take his laptop out of its bag. It is meant as a mild protest, a reminder that he has decades of flying experience and does not need instructions. The trouble is that airport security today looks nothing like it did before 2001, and officers are trained to treat every passenger, regardless of frequent flyer status, the same way.
The Transportation Security Administration was created in the aftermath of the September 11 attacks specifically to standardize screening across every commercial airport in the country. Grandpa’s decades of experience actually predate the very agency asking him to take off his shoes, which is exactly why the comment lands with such irony at the checkpoint.
2. “It’s just a pocketknife, I’ve carried this thing for forty years”
Few sentences trigger a secondary bag search faster than this one. Grandpa is not trying to smuggle anything dangerous; he genuinely forgot that the little folding knife on his keychain, the one he has carried since disco was popular, is now a prohibited item in carry-on bags.
Current TSA rules are clear that pocketknives, box cutters, and most blades are not allowed in carry-on luggage, though they can typically go in checked bags. Grandpa’s sentimental attachment to the knife does not change the rule, and officers hear some version of this exact protest on a near-daily basis.
3. “Back in my day you could bring a full bottle of anything”
This one comes up whenever a water bottle, a travel-size shampoo, or a beloved bottle of aftershave gets pulled from the bag. Grandpa remembers a time, correctly, when liquids of any size sailed through security without a second look.
The 3-1-1 liquids rule, which limits carry-on liquids to containers of 3.4 ounces or less inside a single quart-sized bag, has been in place since 2006 and remains standard policy at checkpoints across the country. It was introduced after a transatlantic terror plot involving liquid explosives was disrupted, a piece of history grandpa often skips right past in his retelling.
4. “Just let my grandkid come through with me, they’re only ten”
Said with the best of intentions, this line tends to confuse rather than charm the officer directing lines at the walk-through metal detector. Grandpa assumes flexibility that simply is not part of standard procedure, especially at busier hub airports.
The Transportation Security Administration does allow children twelve and under to keep shoes on and generally receive somewhat gentler screening, but they still go through detectors individually and families are still expected to follow the posted lane instructions. Trying to walk through together, even briefly, is the kind of thing that gets flagged instantly on camera.
5. “I don’t need to take my shoes off, I’m not a suspect”
Grandpa says this every single time, and every single time he is asked to remove his shoes anyway. It is less about defiance and more about a genuine belief that shoe removal is somehow optional or reserved for people who look suspicious.
Shoe removal has been standard TSA policy since 2006, following the failed 2001 shoe bomb attempt, and it applies uniformly regardless of age, appearance, or how many frequent flyer miles someone has racked up. TSA PreCheck members can skip this step, something grandpa often does not realize applies to him too if he simply enrolled.
6. “I’ll just carry the fishing hooks, they’re harmless”
Fishing gear is a surprisingly common source of confusion at checkpoints, especially among grandfathers headed to a lake house or a coastal trip. Hooks, in grandpa’s mind, are tools, not weapons, and the idea that they might raise a flag seems absurd to him.
Small fishing hooks are generally permitted in carry-on bags under current TSA guidance, but larger tackle, certain leaders with wire, and anything resembling a blade inside a tackle box often is not. The inconsistency between what is allowed and what looks alarming on an X-ray screen is exactly why this conversation happens so often at regional airports near fishing destinations.
7. “I don’t need my ID, everyone here knows who I am”
This joke lands fine at the dinner table but falls flat at the identification checkpoint. Grandpa means it as a bit of charm, a nod to how memorable he assumes he is, but the officer checking documents has never met him before in his life.
As of May 2025, real ID compliant identification became mandatory for domestic air travel under the REAL ID Act, a rule that had been delayed multiple times over nearly two decades before finally taking full effect. Grandpa’s old, expired, or non-compliant driver’s license is no longer a matter of charm; it can mean additional screening or being turned away from the checkpoint entirely.
8. “I always pack my tools, you never know when you’ll need a wrench”
Grandpa’s toolbox mentality does not stop at home, and he genuinely believes a small wrench or screwdriver belongs in every travel bag just in case something needs tightening. This habit, formed over a lifetime of fixing things himself, does not translate well to modern carry-on restrictions.
Current TSA rules restrict tools longer than seven inches from carry-on bags, though smaller ones are typically fine, and anything larger needs to go in checked luggage instead. The seven-inch threshold is oddly specific, and grandpa’s beloved multi-tool or emergency wrench often ends up being the exact item that trips the rule without him ever intending to break it.
None of these moments come from any real defiance. They come from decades of muscle memory built during a version of air travel that simply does not exist anymore. Airport security has tightened steadily since 2001, and again through rule changes like the 2006 liquids policy and the 2025 REAL ID enforcement deadline, while grandpa’s internal rulebook has, understandably, been slower to update.
