Hi all. Next month, I'm flying KEF-SEA on FI with an onward domestic connection on AS, same ticket.

Reading through this thread and the one in the DL forum, I understand there isn't TSA Precheck for connecting passengers at the intl arrivals area. I have GE/Precheck/CLEAR and will be flying with hand baggage only. Would it be quicker for me to exit to landside and re-enter security, or should I stay airside and go through the connection security?

My connection is 1h40m, so not horribly tight without luggage. However, I'm cognizant of the hike over to the AS gates and possible delays out of KEF. It also looks like there are a handful of other international flights arriving at around the same time (IST, SJD, CDG, LHR) that might clog up the lanes. Just trying to stay ahead of the game!
