Hi, I am posting on behalf of my son in law who's travelling to HI with his girlfriend in a few weeks from Quebec City. Neither speak English very well and they have a routing YQB-EWR-HNL-KOA with decent (several hours) connection times. They've asked me to help make sure they get through things OK. They have virtually no flight experience so its a bit nervewracking for them. I've flown a lot but won't be with them and have never flown via EWR so I'm turning here for help.

1. They will clear US customs in EWR - will they have to retrieve and recheck luggage or just clear customs and their bags pass straight through?
2. Is there a separate lane for connections at EWR customs or does everyone clear together and then go on to their connection?
3. Will they have to redo security at EWR. They have to change from terminal A to C on their outbound and the reverse comming home. The same question applies for the HNL-KOA connection.
4. The last leg (HNL-KOA) is on Hawaiian - will they need to pay baggage fees at YQB AND HNL or can all fees be collected at the beginning of the trip in YQB?
5. Any other advice on the connections. I'm a bit worried since their both so green and don't speak the language. EWR seems a bit daunting.
6. Is their IFE on the planes? Can they use regular (one prong) headsets or do they need the two prong sets. Can they buy these onboard?

I do want to help them and give them the best info possible. I will be meeting them in Hawaii but flying different dates and different routes (YUL-YVR-OGG(stop)-KOA return.

Thanks for any help you can offer.
