Traveling to San Diego with Cremated Remains: Flying, Shipping, and Paperwork

How to bring cremated remains to San Diego for a ceremony at sea: TSA screening for flights, USPS Priority Mail Express shipping, and the papers to keep close.

Many families travel to San Diego for a ceremony at sea, and the ashes need to travel too. Whether you carry them on a plane or send them ahead by mail, a little preparation keeps the journey calm.

Flying with Cremated Remains

The Transportation Security Administration allows cremated remains in carry-on and checked bags, with special instructions for carry-on.

• The container must pass X-ray. If officers cannot clearly see what is inside, it cannot go through the checkpoint. TSA suggests a temporary or permanent container made of a lighter material such as wood or plastic.
• Officers will not open it. TSA says that out of respect for the deceased, officers will not open the container, even if you ask.
• Check with your airline. TSA notes that some airlines do not allow cremated remains in checked bags. Many families keep the ashes in their carry-on.

If the urn is metal or stone, ask your funeral home about transferring the ashes to a screenable temporary container for the trip.

Shipping Ahead by Mail

The U.S. Postal Service accepts cremated remains for domestic shipping by Priority Mail Express only. Its Publication 139 sets out the requirements:

• The inner container must be strong, properly sealed, and sift-proof.
• Cushioning goes all around the inner container.
• The outer package must be the USPS Priority Mail Express Cremated Remains box, available from the Postal Store on USPS.com and at some post offices.
• USPS suggests a slip inside with both addresses, in case the label comes off.

Call (619) 986-7344 before shipping to arrange where the package should go and who will receive it.

Papers to Keep with the Ashes

California requires a Permit for Disposition of Human Remains, usually obtained by the funeral home or crematory, showing scattering at sea as the place of disposition. Keep a copy of the permit and the cremation paperwork with the remains while you travel, and bring the permit to the ceremony. If the death occurred outside California, ask your funeral home which papers apply and call ahead so the crew can confirm what is needed.

For the full sequence of documents, see the paperwork timeline and the California ash scattering permit guide. For the day itself, see what to bring. Guests gather about 20 minutes before departure, so there is time to settle in once you arrive.
