Travelling with an urn: flying, driving and shipping ashes

Flying: the container material decides everything

TSA screens crematory containers by X-ray and will not open one under any circumstances, even at your request. If the scanner cannot see through the container, it cannot be cleared — and it will not fly.

That rules out solid stone and thick metal for the flight itself. Use a temporary container in a lighter material for the trip and transfer the remains into the permanent urn on arrival, or check the urn separately if your airline permits it.

• Screenable at security: wood, plastic, cardboard, and other lightweight, non-lead-lined materials
• Usually not screenable: solid marble, granite, thick brass, steel or lead-lined containers
• Carry the cremation certificate and, if you have it, the death certificate
• Check the airline's own policy — some require the urn as carry-on, others allow checked

Shipping ashes within the US

USPS is the only carrier authorised to ship cremated remains domestically, and only via Priority Mail Express with Cremated Remains labels. Major private couriers do not accept them for domestic shipment.

Pack the sealed inner container in a sturdy, sealed outer box with cushioning, and include identifying information inside the package as well as on the label.

By car

Driving is the simplest option and has no special rules. Place the urn in the footwell behind a front seat or strapped into a seatbelt, not in the trunk where it can slide, and not on a seat unsecured.

For long trips, keep it out of direct sun on the parcel shelf — heat and UV are hard on wood finishes and on any adhesive seal.

Crossing borders

International travel adds paperwork: destination countries commonly want the death certificate, the certificate of cremation, and a letter from the crematory or funeral home stating that the container holds only cremated remains. Requirements differ by country, so confirm with that country's consulate before booking.

Common questions

Will TSA open the urn?

No. TSA officers are prohibited from opening a container of cremated remains, even if you ask. The container must be screenable by X-ray to be allowed through.

Can I fly with a marble urn?

Generally not through the security checkpoint, because X-ray cannot see through solid stone. Fly with a temporary wood or plastic container and transfer the remains into the marble urn when you arrive.

How do I ship ashes in the US?

Use USPS Priority Mail Express with the required Cremated Remains labelling. Other domestic carriers do not accept cremated remains.

What paperwork should I carry?

The certificate of cremation, ideally a copy of the death certificate, and for international travel a crematory letter confirming the contents. Keep them with the urn, not in checked luggage.
