This is brilliant timing. I read this sitting at the gate for a short hall flight. There was still a lot of time before the flight and they announced "can Anna something please come to the desk", and about 40 people (I counted as had so much time still) stood up and rushed to queue up and then had to stand up for another 30 minutes until it actually started boarding...
It was a cheap airline so overhead space can be difficult but I really don't get the people who rush to sit down in the tight horrible seats (designated seating btw) waiting for everyone else to sit.
We arrived and then the picture happened of course...
