Hi flippy,
I travel quite a bit in a year, due to my work.
Many years ago....If i was given a tenner every time an airline placed me next to a rather obese man or woman, i'd be very rich by now! lol
No arm space no leg space seems thay haven't yet discovered soap..yuk!....and the annoying habit of spitting their food when they eat the meal.....i now try and travel first class, if alone, which never guarantees anything but at least you get a bit more comfort.
I love travelling economy when going on family hols though, as we are a family of six and take up a whole row!
