This worked well on my ATH-YUL today up until I had to restart my phone (due to something else). The in-flight wifi page recognized me after the restart and indicated the messaging plan was (still) active, but everything was blocked as if I hadn't yet activated any plan. Not a cookie situation since it carried over to another browser when I tried to re-trigger the activate prompt in the browser, didn't reset after disconnecting from the wifi or forgetting the network entirely, so I gave up and just watched a documentary. Was working for my partner, so also not a satellite connection issue. 8/10.
