Last flight I was on did a big ass loop. Kinda wanted to ask the pilot why he did that, but it was a longer than expected flight and I just wanted to go home. The weather was shit, so I’m guessing the airport was temporarily closed because of that. Probably the pilot knew the weather situation and took on extra fuel so he could just fly around for a while if the airport was temporarily closed.

So yeah, there’s a lot of little details that would make sense if you’re on the plane, but looks really weird if the only thing you’re looking at is a flight path.
