So the following idea came to my mind, given the rush to get more and more ancillary revenue, why don’t airlines create a list of famous or important people that have flown on a given aircraft, even on a particular seat, and “market” this experience to the public?
Time to add some plates to aircraft seats too?
The same way that some old houses have historical plates that recall the people that have lived in them, why not airplanes?... well, to be fair, I see a major obstacle with this: whereas age might be perceived as a positive attribute in a house (because a long history might give it its character), it might have quite negative connotations when applied to what is, after all, a flying machine (old equipment!).
Nevertheless, you do not need to go back that many years, there are plenty of contemporary icons that could serve this purpose well (football players, artists, celebrities). Airlines would just need to take care not to highlight these "celebrity seats" past a certain amount of time, and keep renovating them...Anyone willing to pay extra to seat on the same seat that your favourite sportsman sat on when flying to that important match? Judging by the video below, maybe Turkish Airlines is well positioned to do it...
