Let's have a think about it... You would effectively need to have a 4 headed cable.... 4 male plugs all joined together at some point leading to a female plug or directly to the appliance.

The problem here is that when you plug in the cable into seat 1, the protruding prongs on the plugs on cables 2, 3 and 4 are now live/hot. Add a bit of unexpected turbulence or someone misjudges things and that's someone who is now in need of medical attention. You could probably do something to mitigate this with inline switches but they would need to be double pole (both live/hot and neutral) and ideally switching all 4 cables at the same time. These kind of switches do exist but typically only for commercial/industrial applications.

Another issue is that you or I don't know the detail of the aircraft electrical supply. Most importantly is whether the supply to these different seats are all in phase with each other. If they are not in-phase then you would likely end up with some kind of kaboom when connecting sockets together that have different phase supplies. Whilst I am sure there are RCD/GFIs deployed on these circuits, you just don't know how it's all going to react. Joining together AC circuits from different phases always has a bad end result. Any other devices on the same circuit will also see an electrical surge and over-voltage situation and you might now blown other passenger devices and depending on the electrical blast radius, maybe also impact other stuff.

A different issue is that although the inferred supply is 125W per seat, you can also assume that there is some circuit and power protection for multiple seats, and it's highly likely that should all these sockets you are targeting be on the same protection device, the device would be rated lower than the maximum theoretical rating of (say) 500W. Exactly what the margins are here it's impossible for me to say. Assuming there was any sense in this idea (which there isn't) you would not be trying to target the full rated power draw through any one circuit so this would suggest that adding a 5th seat supply would be sensible. Which of course it wouldn't be for other reasons.

This is so dangerous from an electrical point of view, I wouldn't be surprised if this was discovered and there was any smell of anything having gone wrong (let alone a whiff of a hotdog) I wouldn't be surprised if you were not slapped with a lifetime ban, and that just assumes it didn't cause a problem where the aircraft didn't have to divert due to a medical emergency arising from electrocution, or being met at the aircraft door by Her Majesty's Constabulary (or other equally fine local law enforcement) due to high-flying stupidity and probably something along the lines of endangering an aircraft.

Just stop. Stop now. Pranks are all very well but safety is not something to risk at 30000 ft.
I had thought about replying with the same, but didn't want to be that guy in case everyone else was in on the joke, so thank you for being that guy. Any sort of parallel cable with multiple male plugs is incredibly dangerous (along the lines of generator "suicide cords"). Even dual pole switches to isolate while connecting still leave the hazard (imagine a plug gets knocked out). I suspect the onboard outlets are on isolating transformers and/or with some sort of GFCI protection, but that doesn't protect someone who touches both prongs with opposite hands. And there's no guarantee the draw will be evenly divided from multiple outlets, so you're likely to trip one, then the load will be too much for the rest tripping them.

The only way to do something like this would be to have separate isolated heating elements, each under the rated capacity and separately wired to their own plug to combine the heat. But I doubt you'll find that in Target! And no, I'm not suggesting doing that in any way shape or form.

You could try buying them at WH Smiths after security. I would enjoy watching that.

Is that after you have done the needful?

You called that one right - it's not even remotely funny.

It's the typical wind up... it runs out of steam, drops off the first couple of pages, so the OP posts some "fuel" to get it going again

Dont worry, its actually a cello so has its own seat.

Please send flight details when known - between the FT collective I'm sure one of us could alter a travel plan to act as expert witness?

Or rather, plan to avoid the flight given the clear disruption the OP will cause by fully intending to pursue this!

Can the mods change the OP's nick to Scotty?

I'm fairly sure that "picking up" the case at security to put it on the belt would be a major problem, if it hadn't already collapsed the luggage trolley.

At around 170kg or 375lb that is quite possible.

It is now June 10 in the US and inquiring and interested minds wish to know if the trip was a success or has it still not happened yet?

Probably forgot to plug in his electric alarm clock and missed the flight.
