My wife and I are flying from Vancouver -> ICN on Air Canada with some friends and are arriving about 4-5 hours ahead of the rest of the group. We both are members of Priority Pass, Lounge Club, & United Club. Is there a way for us to visit a lounge for a few hours after we get off the plane or will we be ushered directly through customs and out of the terminal? (I assume there is no way for us to get back into the terminal for a few hours and visit the lounges after going through customs.)

Has anyone experienced this or have any tips? Thanks!!
