Not counted
In the late 80's I flew Garuda from Ambon to Surabaya - a jet of some description 100+ seats
We all boarded and doors closed. Then became apparent there were more passengers than seats - solution to squeeze 3 smaller passengers onto 2 seats etc. There were a significant excess.
And I remember that we seemed to use the whole length of the runway before lumbering into the air. Upon which there was an announcement that all the baggage had been left behind.
Not strictly relevent to the thread, I'm afraid......
