Quick answer
Tiny snow globes (smaller than a tennis ball) may pass cabin screening. Anything bigger goes in checked baggage.
Cabin vs checked
| Size | Cabin | Checked |
|---|---|---|
| Mini (<6cm diameter) | Usually OK | Yes |
| Standard souvenir (8–10cm) | No | Yes, padded |
| Large display globe | No | Yes, padded |
Why so strict
Security can't measure liquid sealed inside glass. They size up the whole container — if it looks like it could exceed 100ml, it's out. TSA, UK DfT and EU all apply this rule.
Packing tips
- Wrap in clothes inside a hard-sided suitcase
- Put in a zip-lock bag in case the globe cracks at altitude
- Buy it duty-free after security where possible
- Avoid handing it as a gift at the gate — it'll be checked again
