Forgive me for starting a new thread, but I've tried to find all the information piecemeal on the other threads and I just want to make sure I understand what I'm getting into.

I've got a reservation for 4; as a 1K, I am the only elite in the group and it's a roundtrip with connection.

1. I understand the only way to get a CPU would be to split the PNR into 2 and 2. What happens to the E+ seat assignments of the 2 GMs who end up on their own PNR? Do they lose the E+ seats?

2. Once split, it sounds like there is still a good chance that my elected companion and I will get split up , especially since the first leg is ORD-IAH. What will happen to her itinerary then for IRROPS? Does the second segment clear with the same priority as the first or is she on her own when we get to IAH?

3. I've heard the instructions to elect out of auto-check in for the return, but the last time I checked in using the mobile app, I unchecked the box and it still checked me in for the return. So how to I make sure to stop the auto check-in?

Thanks
