I guess the boxes don't care, but at UAL at least one pilot is probably on SkyPath (real-time turbulence crowd sourced automatically from other airliners whose crews have iPads and SkyPath enabled -- mostly UAL, SWA, and AAL at this time. It's incredibly, incredibly useful to help us find the best rides and keep the FAs safe from turbulence related surprises. And of course it needs Wi-Fi to function. That, and WSI plus Jepp FD are incredibly useful for strategic weather avoidance.
I also flew 121 long before in-flight WiFi was a thing.
But I just did a Hawaii trip with inop WiFi and it was honestly annoying not having the turbulence and radar info instantly accessible.
Plus, how else are you gonna snipe that premium trip that gets taken within 5 minutes of being posted?
