I traveled from San Francisco to Johannesburg. It was two flights, one to Berlin and then on to Johannesburg.
The first flight gave us the usual jet lag going to Europe. The problem was our flight from Berlin to Johannesburg left in Berlin’s evening. It’s an 11 hour flight so the idea is that you sleep on the plane and arrive in the morning after 8 hours of sleep.
But that only works if your body is already in GMT+1!
So while everyone else slept the whole way, we were wide awake! I took pictures of the navigation display the moment we crossed the equator.
But man was I messed up when I arrived. 11 hours on a plane and no time change is just so strange.
