Flying from UK to Kauai through Seattle next summer. I had to book this on two separate bookings as I used an Amex 241 voucher for my LHR-SEA flights then booked separately on AS to LIH. Baggage obviously won’t be check through although we will have completed OLCI so should have boarding passes. Once we collect bags and get through customs/immigration do we have to go landside and bag drop or as read in the wiki will we be able to get the bags retagged and placed on transfer belt?

I’m not overly bothered about heading airside and going back through security but I’m pretty sure bag drop won’t be open as it will be around 5 hours before departure that we would likely have cleared immigration.
