Watching TV on an airplane is the #1 reason I would buy a VR headset. The in-seat screen UIs are atrocious and they tend to only have ~4 or so episodes of any given show. Unfortunately, the Oculus Go's battery life is only about 2 hours according to the Ars Technica review[1]. Some planes have AC outlets, but YMMV.

For the record, the upcoming Lenovo Mirage Solo headset has a 4000 mAh battery and (purportedly) 10-hour battery life. Of course, it is double the price of the Oculus Go.

it looks like it is available now: https://www3.lenovo.com/us/en/tablets/virtual-reality-and-sm...

I saw a review that mentioned Oculus discouraged using it while it was plugged in, so even on a flight with outlets you wouldnt be able to watch 2 movies on a 4 hour flight with it.

What about the noise level on a plane? Are they able to cancel that out?

You can provide your own noise cancelling headphones - you're not forced to use the headphones integrated into the strap.
