I won't even begin to regail you all with my horror stories, suffice to say that I travel around Europe pretty much every week and you can guarantee that at least a couple of times a month you will get on a flight that makes you think seriously about the merrits of train travel.
However it was all topped off on a flight back from Rome last weekend (which had ironically been for pleasure, not business). We had not one, not two, not three but four - yes FOUR - screaming babies on board. And then the mother of one who was sitting one row in front of me and opposite decided to change her kid's nappy/diaper which was full of baby $£%&, but instead of taking the kid to the bathroom, she just did it right there in the seat, making most of those around less than impressed.
