Hi! I accidentally booked ticket with different frequent flyer number than I wanted. I managed to change it later in manage booking page. However, newly-generated e-receipt still shows and probably will forever show the wrong FFN. That is bit odd as seats got updated in eReceipt while FFN seems to be forever fixed. This can not cause any confusion when it comes to Avios/Tier points crediting later right? I wanted to cancel and book again with all details having entered correctly, but fare just raised.
