I, for one, have noticed fewer flights last year that there had been in previous times when I had to fly last year. So it seems to be getting progressively worse over time.
Both posters above are, I think, correct. My hope is that I will never again have to travel using those infernal airlines again. Until I die, at least. I will be buried at Mount St. Michael's cemetery in Spokane but live in Indiana. Bodies are ordinarily transported by air. I asked about using UPS Ground, but was told that wasn't an option.
I don't mean to be intrusive, but as a part time assistant at a mortuary I'll take the liberty to offer some information.
If there won't be any services in Indiana (any or all of a visitation, Rosary, Requiem Mass) you'll want the funeral home's "Forwarding remains to another funeral home" package. They will do the removal from the place of death, handle the required paperwork, embalm (usually required for air shipment, but won't include cosmetology, hair care, or dressing), and arrange for air shipment to Spokane. You (or the person handling your arrangements) will want to purchase a "combo air tray" (designed to transport a body without a casket) in Indiana and purchase the casket in Spokane. The reason for this is that the airlines charge by weight and a 100 lbs. or more will be saved if the body isn't flown in a casket.
Usually a Spokane funeral home would be contacted to receive the remains at the Spokane airport. I'm sure Father Puskorius (or another priest at The Mount) would have an appropriate recommendation. If the only services in Spokane will be the committal at the cemetery (the other services having been held in Indiana), arrangements could be made for a trusted friend with a pickup (with canopy or landau cover) or van to pick you up at the Spokane airport and take you to the cemetery, that would be perfectly legal as long as they have the proper paperwork (which should arrive from Indiana with the body). I believe there is a livery service in Spokane that would provide a hearse for this, at a much lower cost that using a full service mortuary (I'd have to research this).
For a point of reference, about three weeks ago I picked up someone at the Spokane airport who was flown in from Arizona for her funeral in Kennewick, WA. The airfare was about $400. Once a retired deputy coroner from where I live had her father die in one of the Carolinas. She and her husband rented a U-Haul van, packed cold packs around the body, and drove it non-stop to our mortuary in Washington. Usually embalming would be required to cross state lines, but there are exemptions. She, having been a coroner, knew how to handle things, and was comfortable with handling the body.
