My wife and kids are flying YOW-YVR-LAX on reward seats.

They arrive in YVR at 1030 am.
Their connecting flight to LAX doesn't leave till 730pm that evening.

My question is; Will their bags come out at the normal baggage claim area or is there a transborder baggage claim area at YVR?

Can they leave YVR for a few hours with their bags and then recheck them at the transborder checkin at around 5pm?

Sitting at YVR for 8+ hours isn't fun for anyone.

thanks
