Sky priority in W but not in U on KLM
Hello, i travelled with KLM a few weeks back for a EU trip (NCE-AMS-BRU/BRU-AMS-MRS) in economy. My reservation had sky priority on all 4 flights.
i am tomorrow flying LHR-AMS-CDG, also in Economy, but no Sky Priority this time.
I am FB Silver, so at first i thought that KLM gave sky priority to Elite FB members in addition to Elite plus, but this flight says otherwise.
my booking class for my first flight was W and for the one tomorrow it’s U. I guess it has to do with that but could some savvy Flyertalker explain to me how it works ?
thanks in advance !
