Hi Everyone,
My family have round trip tickets booked in Aug. (YVR - LHR) My husband and I cashed in most of our AS miles for tickets in first and bought the kids (17 and 19) tickets in WT. The kids have a different booking number and we have no status on BA.

I've been following the forums here since I booked our tickets in Feb. I've learned that the kids can join us in the lounges, including CCR, but I have questions about whether there are other ways the benefits of our First tickets may "rub off" on the kids.

1. If we use the First check-in desk, can the kids check in with us, or do they have to go to the other line?

2. At LHR, the stated check in time is 3 hrs. prior. If we arrive earlier than that, can the kids check in with us, or will they be required to wait until the appropriate time?

3. Will they be allowed to go through Fast Track security with us?

4. What about Priority Boarding? Will they be allowed to enter with us, or have to wait until their row is called?

Thank you for any help or advice you can offer.
