Where it mentions the exact model of the plane? I never questioned whether you could buy food like that, but none of those photos were taken on an airplane. Ceiling is too high. Overhead storage has no doors. Separator wall has a gap below the ceiling, things you won’t see on an actual plane.

All the windows have curtain, how convenient you cant see if they are actually flying or not. The ceiling height is also suspicously to high, it seems fake. And calling that buzzfeed gallery as an “article” hmm…

What will you do with it? Or is it just a trophy to brag about to your geek friends on the internet?

It doesn’t help much if your cousins signed up with their real name. If you are male, they can figure out your surname even if no close relative submitted samples: https://en.wikipedia.org/wiki/Surname_DNA_project
