I mean I was on a 6 hour flight lately but not intercontinental. I think in general as airlines modernize their fleets these systems will be removed. I remember a few years ago even less than 6 hours flights had small foldable TVs in the ceilings and the audio jack, but they're slwoly getting rid of those. On the last flight I was on you could track the flight path and other things that would normally be in physical form (catalogues etc) by connecting to onboard WiFi on your cellphone, even if you didn't pay to access the rest of the internet.

The flights I've been on in the past years don't even have those systems and instead they expect you to do everything on your mobile device.

I would love to see the athletes protest this and wear whatever that rainbow colour bracelet is. It might have big impact. But they'll probably be threatened with billion dollar fines if they do so. It's sad how fucking retarded these people are.
