I've 45 years as a pax under my lap-belt and STILL no GA. I'm really cross about this and DEMAND my rights for a GA.
500+ sectors as a pax over the past few years and only 1 GA - sods law says it was on one of the bumpiest approaches I've every experienced when I was on a very tight timescale. Had to experience the approach all over again.
Since I have seen folks sleeping all the way from 'top of drop' to touchdown, I'm sure there are those who don't notice.
I've now got this off to a tee but I can do it from boarding to arrival at gate - a great trick when the extra couple of hours sleep is needed
