I remember being a high paid techie getting 19 hours of paid work done between Melbourne and New York, on a laptop in economy (and a long layover in LAX due to a storm). It was fricking glorious, most productive day of my life.

How did you run your laptop for 19 hours in economy class without a power plug? Not even M-series MacBooks last that long.

I mentioned the layover in LAX. Also including an hour or two before takeoff.
