A note that may be useful to some: a week ago I added profile information, including Known Traveler Numbers, to our reservations. Tonight I checked in online, they had my passport information from my IB Plus profile, and I proceeded without looking closely at the optional fields. I proceeded to my wife's check-in, not an IB Plus member, needed to fill in her passport info, then added the KTN, then thought I should look over my info before completing check-in. I didn't see an option to review, just going to Next meant completing check-in, and my wife had Pre-Check while I don't. I'll see at the airport if it can be rerun with Pre-Check for me. This is departing the U.S. and mobile BPs show on the app, without my wife's saying Pre-Check.
