⚠️ 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 Emotional Support Animal for a Flight

Plan an ESA trip as a pet trip, not an assistance trip: since January 2021 US airlines may treat ESAs as ordinary pets, and every major carrier now does — that means a reservation (cabins cap the number of pets per flight), an airline-approved under-seat carrier, a fee each way, and vaccination paperwork. The animal rides through security like any pet: out of the carrier carried in your arms through the metal detector while the empty carrier is X-rayed. If the animal is task-trained, explore the service-dog definition instead.
