I was on a recent flight from Helsinki back to London flying on a new Finnair Airbus A321.
As well as the usual table there was this interesting ledge on the back of the seat in front of me which you could use to prop your phone (or I guess a small tablet) to watch a video during the flight.
Now I would have never guessed this was there or what its purpose was unless the person sitting on my row started using it with their phone.
You weren’t allowed to use it during take off and landing, but otherwise it was useful to have if you either had a drink, or use the table for something like a laptop. Of course, it also allows you to watch stuff without holding the phone (or if you don’t have a stand for your phone).
