Hi everyone. Need some advice please. This Tuesday, 13 August, I'm flying IAD to JFK to AMS to OSL. Then on a seperate itinerary, I'm flying OSL to AMS (yes, I know I will have passed through AMS earlier in the day and it was just cheaper to book going to Scandanavia instead of going direct to AMS). I'm not checking bags. So I was wondering, what do I do when I arrive in OSL since I'm on a seperate itinerary? There's about a 2:55 gap between when I arrive in OSL and when I depart back to AMS. Do I need to go through customs and then past the incoming security checkpoint, and then come back through security to check in? Or can I proceed to the gate since I've already connected through an EU country earlier in the day? Any help would be great. Thanks in advance!
