I purchased an AF-marketed fare, but with a combination of AF, DL, and KL-operated routes. I put my DL frequent flier number into the reservation and I do see the DL-operated flights in the DL app. Yet, the AF and KL-operated flights are not. I downloaded the AF app, but it doesn't seem like I can look up my reservation without having a Flying Blue account. I hesitate to create a FB account and look up the reservation due to the issues that have been described on the forum where my DL number may be removed and FB number polluting the PNR. So what do I have to do if I want a digital boarding pass added to my iPhone or Android phone?
