Is it allowed to take urns with ashes on the airplane?
Yes, you can take an urn, both in the cabin and in the airplane’s hold, nevertheless, you must keep in mind that the transport is subject to the regulations of each country. Therefore, you could need a death certificate and a cremation certificate, among other documents. Also, urns are checked at security points to access boarding gates in each airport and may be opened by the security authorities.
We recommend that you contact the consulate of the country where you wish to travel to learn about the requirements and if you travel to Brazil, check the ANVISA (Agência Nacional de Vigilância Sanitária) [The Brazilian Health Regulatory Agency] website.
