When he started mumbling did you even bother to ask the guy if you’re disturbing him. Have a conversation. See if you can make some adjustments.
You guys were obviously too wrapped up in yourselves until he really escalated to care.
And the way you’ve tried to out-logic everybody who doesn’t have the same opinion as you in this thread shows me that you feel entitled.
You started this thread and now you can’t even except peoples opposing opinions... and try to twist their logic around. Nice. It just makes you look worse.
Airplanes are already full of annoyances and people doing weird and inconsiderate things. Last thing we need are more entitled frequent-flier passengers who are so inside themselves think they can talk as much as they want without bothering anyone and read under a spotlight without bothering anybody else around them. (And don’t demand like some in the thread above that other people bring earplugs and shades when you can just as easily bring a Kindle or an LEDUSB powered reading lamp that is much more personalized)
Personally, I think both the pilot and you guys were out of line. He was raging and you guys were rude and tried to ignore his discomfort. Maybe the best outcome is for both of you to have to sit in front of a row of kids that kick the back your chair to the beat of house music for an entire transatlantic flight.
