Result is that nobody needs to wonder about who is boarding when from where and in which order. I should've taken some photos, but boarding went so fast I didn't have time to get some. Everybody liked that.
Got an email in my inbox for an event. In the marketing text, this section is included
"[...] and most importantly, amazing instagram photos to make your friends have serious FOMO."
That's when I instantly know, that I'm not supposed to go to this event.
