If the airline insists, then make sure that the price of the infant ticket will not change (it should not as it is based on the portion of the adult ticket paid). Then apply the passport regularly.
You have more than enough time for a February 2019 travel.
I talked to Chase UR (Expedia) and was told that I can't ADD a ticket for minor to an existing itinerary via their system. They suggest me to contact Cathay directly to do that. The problem is I don't want to pay out of pocket for a separate ticket when I still have Chase UR points. I think I have to pay the $200 penalty for revising an issued ticket to replace my dad with my son and then later on book a ticket for my dad separately using Chase points.
