Tried to remove FF# at the checkin for the first sectors, but was told it had to be all or nothing.
After the removal, the system (app and web) did not allow me to add my FF# back, with the error note indicating ‘only cx members can update their FF#’.. i am a cx member trying to add my cx ff# back btw.
Aftee the removal, one of my selected seats on an ex-KA aircraft was removed immediately, and changed from 12A to 18A.
Will try to have the ff# reinserted durong online checkin or airport. See what happens.
