Quite agree but they also don't want to be disturbed by crying babies, smelly hippies, overweight people in the middle seat, amorous couples who can't leave each other alone. They also don't want to go into a toilet where the previous occupant has smeared their poo all over the walls or sit in seats that someone has left chewing gum on. If they're disabled they don't want to be hoisted on a rickety lifting device or manhandled onto a narrow airline weelchair or told they have to return to their port of embarkation because there are only stairs available to get them off. If you want travel perfection then you need to charter your own corporate jet otherwise we all have to cope with the inconveniences of mass public airline travel.
