Flying Sunday afternoon. I'm flying a PMUA flight and my parents are flying a PMCO flight, both ex-EWR.

1. Will we have trouble doing OLCI on Saturday?
2. How much time should we give ourselves in the airport? (I'm flying international; they're flying domestic. We are all checking luggage.)
3. Will we all be able to check-in together at the Premier Access/eliteAccess desk, as everything will have moved over to a single system?
