Can confirm this is working. In fact, typing this while in flight. Very handy feature to have. Especially the countdown feature to tell me how long I have before they start boarding, and how long I have left on my flight. (Images edited to censored out some details)
Now if they would fix their inflight catering from stateside. (Meals on Polaris is just economy unfortunately, not worth getting the upgrade at all. And for this flight, flight completely full so couldn’t upgrade with my status regardless)
