It’s the one mistake that could ruin your holiday before it’s even begun – and it happens more often than you’d think.
Why you should never pack your passport in your carry-on – unless you fancy an airport disaster.

Planning a holiday? Packed your suncream, chargers, snacks… and stashed your passport in your carry-on suitcase? Stop right there, sunshine – that innocent little habit could turn your dream trip into a passport panic.
In 2024, the EU recorded 6.7 million commercial flights—a 5.8% jump from 2023’s total of 6.3 million, as Europe’s skies grew busier than ever.
Spain’s Aena airport network wrapped up 2024 with a record-breaking 309.3 million passengers, marking a 9.2% surge from 2023. The skies were just as lively, with 2.59 million aircraft movements—up 7.8%—while freight transport soared to 1.28 million tonnes, a hefty 18.6% increase on the previous year.
That’s a lot of people jetting off – and plenty of chances to fall foul of one of travel’s most costly mistakes: storing your passport anywhere except physically on you.
Because once you’ve handed over your beloved cabin bag at the gate for a last-minute check-in – poof! Your passport’s now in cargo limbo, and you could be stuck at border control looking like you’ve tried to enter a country with nothing but vibes and a boarding pass.
Bag check blunders: A passport to disaster
Thanks to airlines playing Tetris with their luggage policies and charging extra for checked bags, more travellers are cramming their lives into carry-ons. But here’s the twist – flights are full, bins are overflowing, and more and more people are being forced to gate-check their bags just before boarding.
If your passport’s in that bag and you forget, and you’re bound for international pastures, say goodbye to smooth sailing.
Why? Because you always go through immigration before you’re reunited with your checked baggage. No passport = no entry. Cue interrogation, missed connections, tears at the terminal and an emergency flight home.
Flying from London to LA with a stopover in Madrid? If your passport’s locked away in your suitcase during that Madrid stop, you’ll be denied access and almost certainly miss your connecting flight – if not worse.
It’s not just checked bags – there’s theft, too
Even if you aren’t forced to check your bag, your passport is far from safe. In-flight theft might sound like the plot of a dodgy Netflix drama, but it does happen – especially when overhead bins are crammed and your bag’s ten rows behind you.
Out of sight, out of mind – and easy pickings for opportunistic fingers. More common, though? Good old-fashioned forgetfulness. Once you’ve landed, all it takes is one distraction – a crying baby, the dash to passport control, or simply the holiday daze – and your passport could be halfway to Lisbon without you.
Real story: British couple booted from Greece
Still not convinced? In 2018, a young British couple flew to Greece and accidentally left their passports on the plane. Before they could shout “Opa!”, they were marched back onto the next flight to the UK.
“There [were] people watching us like we were criminals,” they told The Independent.
“They gave us a boarding pass and chucked us on the next flight, we didn’t get a choice.”
Their passports were never seen again – likely swiped, binned or swallowed by airport limbo. Cost of replacements? Up to £100 each. Not to mention the stress, missed holiday, and the shame of telling your nan you never even made it to the beach.
Barcelona blues: Bag stolen, holiday ruined
One traveller learned the hard way last summer when they arrived in Barcelona, passport zipped snugly inside a pricey Briggs & Riley carry-on.
“Within minutes of reaching downtown, before I could even hail a taxi, thieves grabbed my carry-on and disappeared into the Rambla,” the traveller wrote.
Cue days of police reports, emergency passport applications, and a second theft – this time, their phone.
The golden rule: Keep it on you – always
Seasoned travellers know the drill. Your passport should never leave your side. That doesn’t mean you need to strap on a neon money belt like it’s 1998. These days, there are plenty of discreet, stylish options – crossbody bags, zippered pockets, travel trousers designed to keep your documents safe but accessible.
And at the very least? Keep it in your personal item – the bag that lives under the seat in front of you and never leaves your sight. You’ll need your passport for check-in, security, boarding, and arrival. Lose it at any of those points, and it’s game over.
Bottom line: passport in your bag = holiday in the bin
With record numbers of people travelling and airlines getting stricter with baggage rules, it’s never been riskier to tuck your passport away in your carry-on. One misplaced bag, one gate-check request, one sticky-fingered thief – and your relaxing holiday becomes a bureaucratic nightmare.
So repeat after us: wallet, phone, passport, ON MY BODY.
And if in doubt? Remember this simple rule:
If it can ruin your life, don’t put it in the overhead bin.
