⚠️ Common Traveler Mistake to Avoid

The Mistake: Assuming scissors or tools of any size are allowed without checking blade length from the pivot point.

How to Avoid It: Measure blade length: must be under 4 inches (10 cm in the US) or under 6 cm from pivot (in Canada).

How to Pack Balloons for a Flight

The TSA entry reads “Balloons (not inflated)” — Yes in both bags — which quietly tells you the correct way to fly party supplies: flat-packed latex or foil, inflated at the destination. Never pack a helium tank: pressurized gas cylinders are banned from passenger baggage entirely, and venue vendors everywhere will inflate for a few dollars. A fully inflated balloon is cabin-legal in substance but absurd in practice; remove the air and win the space back.
