I just flew with JAL and purchased inflight Wi-Fi, hoping to get some work done. A few minutes after I connected, not only was it slow (which I would understand), but various office applications wouldn't connect. When I tried to do it via websites, it asked for two-factor authentication, which required my phone to be connected.When my phone connected, my PC got disconnected. Once I got my PC back online, it asked for authentication again. As a result, I ended up just crafting emails offline with occasional browsing.This was simply the worst Wi-Fi experience I've had. I'm curious if this was a common theme, or was I wrong to assume I could work during the flight?
