1. The toothpaste and liquids mistake
It sounds minor, but it’s one of the biggest causes of delays.
It doesn’t matter if the container looks small—
what matters is the size printed on the label.
Many “travel-sized” items still exceed the allowed limit, and security checks go strictly by numbers—not appearances.
How to avoid it:
- Always check the exact volume (ml or oz
- Use approved travel containers
- Keep medical liquids separate and clearly labeled
2. Carry-on size surprises
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
