Most recently flying Melbourne Gold Coast solo in January 2016. I was in the aisle seat in row 5, 5c from memory. Couple arrive and she insists she must have an aisle as she is scared of flying. She insists her husband always allocates an aisle. I point out they are in fact in middle and window. He looks at the floor and moves into the window seat, he didn't say anything. She grudgingly got into the middle seat and spent the whole flight complaining to me as they were QC members and she needed the aisle. I held my tongue and tried to block it out with headphones. What I wanted to say, amongst other things, was obviously her husband knew exactly where they were sitting, he just hadn't told her!
