Human remains are mostly carried on cargo flights
Generally, if the deceased has been embalmed, an ‘air tray’ is used to protect and conceal the coffin. This is not actually a tray, but an outer container that meets the airline’s regulations.
If the body has not been embalmed – or has died of a contagious disease (e.g. covid) a ‘Zeigler air tray’ is used. This is a hermetically sealed container made of 20 gauge steel.
The flight alone can be as much as £20,000 – however there are many extra costs – e.g. funeral directors in both countries, paperwork and Zeigler air trays, etc. Frank’s top tip – get travel insurance – which will not only cover the costs, but help you with the process and paperwork.
