The couple were on a Qatar Airways flight from Australia to Qatar. The airline apologized.
Summary
A couple on a Qatar Airways flight from Melbourne to Doha was forced to sit next to a deceased passenger for four hours after she collapsed and died mid-flight.
The flight crew moved the woman’s body to an empty seat beside them and denied their request to change seats.
Qatar Airways apologized but did not offer the couple support after the incident.
The couple, en route to Venice, criticized the airline’s handling of the situation but are trying to continue their trip despite the distressing experience.
I think the only thing they're pissed about is the airline didn't allow them to move seats after they put the woman not in her original seat and probably being forced to stay on the plane longer than needed, potentially missing their connection to Venice, while medics came on board to haul her away.
Most of the planes I've been on had at least some crew seats tucked into the back and out of the way of the primary exits if I am remembering correctly. There probably is a good reason, such as tripping hazards for the crew doing their work or the seats not really being effective for long term seating and keeping the body in place (I'm thinking of the fold down crew seats).
Flight crew are seated next to emergency exits during landing, they would occupy all crew seats except for any in a crew rest area (which is reached by ladder).
It's a dead body, it won't harass you. They might get rigor mortis but decomposition won't have time to start. Passengers comfort is last priority while balancing a metal tube going 900 km/h though the stratosphere. Some compensation can be arranged when back on the ground.
Technically, there was at least 1 free seat since the woman wasn't using it anymore.
But that begs the question, assuming the entire plane was full then the lady was sitting next to at least one other person. They moved her from that seat to be in next to the couple in question. So it seems to me there is no situation where it's not extremely messed up.
I think the problem likely comes down to safety and respect for the dead.
Put the body in the back galley and suddenly the plane hits rough turbulence and that body is now a +100 pound projectile.
Putting the body in a bathroom seems better, but that turbulence hits and now the body is flying around in there during the rough turbulence, and then the next day the media is lambasting the air line for desecrating the body or whatever.
I think it's more the nature of modern air craft. There isn't much spare room and space is extremely expensive on planes. Meanwhile, these deaths rarely occur.
There's probably some way to design a system to secure a body in the bathroom, however, and I broadly agree with you that they should have some type of solution.
I imagine any solution they come up with will be out of sight until it's needed and you could equip multiple bathrooms or whatever space. Although two people dying like this is probably astronomically rare.
