Getting rid of the printed menus reeks of a Kirby-like cheap cut. I encountered it once and thought it was a one-off. My guess is if they don’t get enough pushback, they will disappear entirely. No offense to the FAs, but they cannot memorize the description of the meals to the point where they can replace physical menus.
Having flown plenty of non-UA flights in international J this year, it is embarrassing how poor their product - both hard (given the slowness of Polaris rollout) and soft (no explanation needed) - compares. Someone needs to tell these folks that you have to spend money to make money.
