You pass security easily… but at the gate, they ask you to check your bag size.
That’s where things go wrong.
Wheels stick out.
Handles don’t fit.
The bag is overpacked.
Result: it gets checked in—and you pay extra.
How to avoid it:
- Measure your bag including wheels and handles
- Don’t overfill your suitcase
- Check your airline’s exact size rules
- Keep essentials in your personal item
3. Documents that stop you cold
A small detail can prevent you from boarding:
Expired or nearly expired passport
Damaged documents
Name mismatch on your ticket
How to avoid it:
- Double-check everything before your trip
- Make sure names match exactly
- Carry digital backups of important documents
4. Problems with batteries and devices
Security doesn’t take items randomly—they remove what they can’t quickly verify.
Loose batteries, unclear capacity labels, or damaged devices raise red flags.
How to avoid it:
- Keep batteries in your carry-on, not checked luggage
- Make sure capacity labels are visible
- Use protective cases
- Avoid unbranded or unclear electronics
