Thanks visitor. I really appreciate that you cared to reply.

I have emailed various Airlines (including United). All of them told me to contact a local funeral house saying that the funeral house will provide the shipping rates. I will do that surely - but it will be of great help to me if I have some idea of what to expect both cost-wise and documentation-requirements.

Once again, I hope people in the broad Nepalese community in US who might have been involved in similar situations would also care to reply.
