I found this forum having tried to find the answer on Google. I was on a B777 coming into Heathrow from Miami yesterday (AA56) and was expecting us to go into the usual hold. The attached picture showed we did ultimately do that but not after making a seriously tight circle. I thought at the time this was unusual in such a big plane so looked it upon flightradar (link below) and you can see just how sharp it was. Is this normal? I'm not the best flier so was pretty freaked out. I'm sure it's fairly common but I have never experienced anything like it, short or long haul.
