Got quite a few Euro weekend trips coming up first half of the year with the good lady. All trips were booked at same time and both of us same type of ticket and class with the same booking code. Whilst reviewing the flights after a KLM change for one set of flights to Marseille in February, I noted that in all bookings, my good lady is due to receive 25 XP's for the trip whilst I am on 20 XP's. No big deal for me as I have (currently) enough to gain PFL but my wife does not quite have so additional points are welcome.

Should add that nothing extra has been spent (miles or money) for the SAF/Co2 option which we know would gain extra XP's.

Anybody explain why she seems to be getting the extra 5 XP's?
