Carry-on details
Allowed with conditions. Uninflated balloons are a solid item with no restriction. Already-inflated balloons, especially helium-filled foil/mylar balloons, are generally discouraged or may be popped before boarding, since they can interfere with overhead bin space and, for foil balloons, occasionally cause static/electrical issues.
Checked-bag details
Allowed. No restriction in checked baggage for uninflated balloons.
Special instructions
If you need inflated balloons at your destination, it's simpler to buy or inflate them there rather than trying to fly with a bunch already blown up.
FAQ
- Can I bring inflated helium balloons on the plane?
- It's discouraged — airlines and TSA generally prefer uninflated balloons because pre-inflated ones (especially foil/mylar) take up cabin space and can occasionally cause issues. Uninflated balloons have no restriction.
