Quick Answer
⚠️ Soda is considered a liquid by TSA.
✅ In carry-on, bottles or cans must be 3.4 oz (100 ml) or smaller inside your quart-sized liquids bag.
✅ Larger bottles and cans are only allowed in checked luggage.
✈️ Full-size sodas bought after security (duty-free or airport shops) may be carried onto the plane.
Details
- Carry-on:
- TSA only allows liquid containers ≤ 3.4 oz in your liquids bag.
- Standard soda cans (12 oz) or bottles are too large → not allowed through security.
- After security:
- You can buy full-size soda at airport shops or duty-free and bring it on the plane.
- Checked luggage:
- Any size soda cans or bottles allowed.
- Pack carefully to prevent leaks or explosions from pressure changes.
- International flights:
- Same TSA rules apply at departure. Customs rarely cares about soda, but duty-free liquids may be restricted when connecting internationally.
