I benefited from the interesting ones from time to time. Since the beginning of the pandemic, all my business travels stopped and all my flights were personal trips and all but one were domestic and EU trips for obvious reasons. For those trips since May 2020, it happened that I booked 2 or 3 trips in J upfront because prices were good (sometimes cheaper than Y), but for all the other ones in Y, the upgrade offers were all in the 300€ range. So, should I believe that because I booked 3 or 4 trips in J out of something like 20 in one year, I have this suspected insane NDPU mention in my profile? I have the feeling that it is more complicated than this. Could be wrong of course.
