So I will change to Miles and More now. After years not using the upgrade voucher I did it for a flight in August. Because the upgrade voucher are connected with the M&S account I am not sure if I can change the FFP in the booking to Miles and More without losing the upgrades and other benefits, for example the private room in TK lounge in IST because I have a 6 hours layover. Anyone with experiences?
changing the FFP number later will not influence the ticket change, so should not have any impact on the booking class.
Suite Room in IST is quite a nice perk if you match the rules to have access, but that is not linked to an TK Status, you can get access if you are fulfilling the rules despite any status.
