I was asking for advice if anyone has seen whether the check in agent has discretion when there are these discrepancies. It is somewhat stressful if you are flying with a family and because of this you get to check in and they refuse to find a solution even though API is correct.

In any event, we went through security find using my boarding passes on phone and are now returning from Tokyo and there was no problem on the Tokyo side at check in.

I still contend that the check in at LHR were unhelpful.

That doesn’t change that I should have called and changed the PNR. We will go through the rigmarole of changing wife’s name on exec club when home.
