As a interessting observer, I watched last week on a flight from Nice to Munich that a guy came to his seat, unfortunately the seats were taken buy a couple with a toddler on the hips, who had now own seat (cheaper!). No big deal, they were in the wrong aile, the original seats of the couple was one row infront so he said keep your seats ill just take yours. The drawback was that the child started to kick seat and other things. I thought how would I react?

Always resist on your original seats.
