Carry-on liquids and security rules: what UK travellers need to know now
Smart packing and smarter connectivity for autumn journeys
Stranded at Heathrow’s security gate, watching your shampoo bottle being binned by a brisk officer—it’s a rite of passage few admit, but most have endured. Last November, I watched a family from Manchester try to salvage a half-used bottle of olive oil (a souvenir from Italy, apparently) before it disappeared into the forbidden abyss. Rules change, queues lengthen, and every autumn, new stories emerge amongst the Black Friday rush and Thanksgiving getaways.
Carry-on liquid rules seem simple, but the reality? Not so much. I’ve lost count of how many times I’ve seen toothpaste tubes, hand sanitisers, and those fancy eye creams sacrificed to the security gods—all while fellow travellers fumble with plastic bags and last-minute repacking. Honestly, knowing the up-to-date rules is as handy as a portable charger, especially if you’re hopping from London to New York or catching a red-eye into Tokyo this autumn.
Quick Facts
- Only bottles up to 100ml allowed in your carry-on liquid bag (no exceptions for Black Friday shopping sprees).
- Clear resealable bag size: max 20cm x 20cm, one per person—no double-bagging.
- UK airports enforce strict checks, but some US and EU airports have slightly different policies.
- eSIMs (like Graba SIM) help you stay online instantly, so you can check gate changes or airport maps on the go.
- Seasonal tip: Autumn travel means busier terminals—pack light and keep essentials handy.
Travelling this autumn: what’s changing at UK and global airports
I recently flew out of Gatwick for a brisk city break in Berlin, just as the Black Friday crowds began to swell. Security lines snaked around corners, with harried staff reminding passengers about liquid limits every five minutes. UK airports still cling to the 100ml rule (and yes, that applies to sun cream in November if you’re chasing winter sun in Dubai). New scanning tech is starting to roll out in some terminals—Manchester’s Terminal 2 has trialled CT scanners that, supposedly, let you keep liquids in your bag. But it’s patchy: don’t bank on it unless you’ve checked ahead. Stateside, the TSA isn’t much more forgiving, though their bag sizes differ, and US airports often allow larger hand sanitiser bottles (up to 355ml). If you’re connecting through JFK or LAX during Thanksgiving, expect both confusion and crowds.
Why This Matters
Seasonal surges in travel make security bottlenecks more likely. Understanding local rules means less time repacking—and less chance of losing expensive lotions or gifts.
Packing liquids: real-world tips for autumn journeys
Most UK airports (Heathrow, Gatwick, Stansted, Manchester) stick to the standard: all liquids, gels, and aerosols must be in containers of 100ml or less, inside a single clear resealable bag (max 1 litre). Medication and baby food are exceptions, but they’ll still be checked—especially if they’re not labelled. Here’s what I’ve learned the hard way:
Destination insight: how liquid rules differ (and what it means for connectivity)
Last Thanksgiving, I landed in New York with my carry-on perfectly packed—only for the TSA agent to flag my hand sanitiser and a local honey jar bought at Borough Market. The US allows larger sanitisers, but not food items over 100ml, so that jar lived in JFK’s trash instead of my suitcase. In Japan, airport security is meticulous. At Haneda, officers will inspect each bottle, and your liquids bag must be zipped tight—no loose flaps. Island-hopping in Greece? Security staff on Santorini and Athens are slightly more relaxed, but rules remain: 100ml max, 1 clear bag. Notably, local bottled water often exceeds the limit, so buy after security.
Mobile connectivity is a different beast. In New York, public Wi-Fi at JFK is patchy during peak hours; in Tokyo, airport Wi-Fi is reliable but can slow to a crawl at lunchtime. From experience, having an active Japan eSIM or US eSIM plan lets you check flight updates or transport options without relying on congested free networks.Why a digital SIM is the smart packing addition
Weaving through bustling terminals with a physical SIM card tucked in your wallet? That was me in 2019, juggling three different cards for a month-long trip. Now, with embedded SIMs (eSIMs), swapping providers or topping up data is as simple as a tap on your phone. What’s genuinely handy:
Step-by-step: packing carry-on liquids and activating your eSIM
Here’s my personal checklist, honed from years of trial and error: 1. Gather all liquids and gels (including creams, sprays, pastes—yes, toothpaste counts). 2. Decant into bottles under 100ml (label them if possible). 3. Place in a single clear resealable bag (max 1 litre, 20cm x 20cm). 4. Keep bag at the top of your carry-on for easy access at security. 5. Check local airport rules if you’re transiting—some EU airports trial relaxed restrictions, but don’t rely on it.
7. Choose your eSIM plan; activate via QR code or app (I usually do this at home the day before).

Local Tips
Comparing eSIMs, roaming, and airport Wi-Fi
| Option | Speed | Convenience |
|---|---|---|

Final thoughts: packing smarter and staying connected
Final Thoughts
Packing for an autumn trip is never just about the weather or what jumper to bring—it’s the small things, like that hand cream you didn’t want to lose or having data when your gate changes at the last minute. Honestly, I’ve learned that a little planning saves a lot of hassle. Whether you’re city-hopping for Black Friday deals or crossing continents for Thanksgiving, knowing the liquid rules and sorting your digital SIM ahead of time makes the difference. A warm cup of tea at the airport helps, too.
