The KLM code seems to be back again but I've noticed something strange that makes me wonder if it really is. When booking on the website the code works and all fees and insurance is included. Pulling up the reservation on the app, National separates and charges for the insurance and fee's. Thus the total price is now significantly higher. The reservation cannot be canceled/modified on the app at all either. It says you have to call in. This is only with the klm code applied. All other reservations with the default emerald code or other is normal.
