Question about PAT and linking reservations

[Gzub1003]

1. Do I need to have everyone’s passport info to get my PAT when I do online check in?
(My kids passports are on there way but don’t think I will have them at the 30 day mark. Also because they are new passports I don’t have there birth certificates either)
2. We have 2 separate reservations I linked them through the app so does that mean we will automatically be seated together for dinner or do I have to call to make that happen.
Thanks for you help

In order to reserve a PAT, all other sections of online checkin must be complete. You will need to enter something for your child’s ID before getting a PAT.

You can say you’re using Birth Certificates and the change it later.
