Can I Bring a Stanley Cup on a Plane? Everything You Need to Know Before Flying
Posted by ERIC WONG
Yes, you can bring a Stanley cup on a plane—but you must follow TSA rules. Get expert answers on bringing your favorite Stanley tumbler for your next flight, airport refill strategies, and how to avoid leaks at 30,000 feet.
Understanding TSA Rules for Stanley Cups
The TSA's 3-1-1 liquids rule means any container over 3.4 ounces (100 ml) with liquid can't go in your carry-on. Your Stanley can come aboard as long as it's totally empty before screening.
Pro tip: Place your Stanley in a screening bin and keep the lid open or off to show it’s empty.
- Empty all liquids before airport security.
- Refill after screening using airport fountains or refill stations.
- Stainless steel bottles may get extra inspection—this is normal.
Stanley Cup Sizes and Air Travel Compatibility
Stanley tumblers come in sizes up to 40oz, all allowed through airport security when empty. The classic 40oz Quencher’s base is about 3.1” wide—great for standard cup holders and plane trays.
How to Fill Your Stanley After Security
Most major airports now offer water bottle refill stations. After passing security, fill your Stanley at the nearest fountain or ask a restaurant for free water. Bringing your own cup saves money and helps reduce airport plastic waste.
“Airport bottled water can cost $2.50–$5. Fill your Stanley for free and stay hydrated throughout your flight.”
Cabin Pressure: Avoiding Leaks and Messes
Air pressure changes at altitude can make straw-top Stanley cups leak or spray. To avoid a mess:
- Open the main lid during takeoff to equalize pressure.
- Don’t overfill—leave space for air expansion.
- Unscrew the lid before sipping for the first time at cruising altitude.
- Remove the straw if worried about pressure spray.
Flip-straw and leak-resistant Stanley models perform best for frequent flyers.
Stanley Cups in Checked Baggage
Want to pack a full Stanley cup? You can do so in checked luggage. TSA liquid rules only apply to carry-on bags.
International & US Flights: Do the Same Rules Apply?
Most countries follow the same 100ml/3.4oz liquid limit for security. Canada, Australia, Europe, Hong Kong and more allow empty insulated bottles through security. Always check the local airport’s rules before flying.

Stanley Cup Air Travel Tips
- Use a carabiner or crossbody strap for hands-free carry.
- Try leak-proof accessories and alternate lid designs for air travel.
