Have you ever tried to get to sleep on a long haul flight on an economy ticket? During my most recent trip, the airline company kindly supplied an inflatable pillow that wrapped around your neck, but there was a sharp-edged seam than ran all the way around the inside of the of the ‘pillow’, so that when I woke up I had a red mark all around my neck that looked like someone had tried to choke me with a clothes line.
