We are flying from Basel to San Francisco via Schiphol on KLM. Depart Basel at 06:45AM and arrive 08:20 Amsterdam. Our flight to San Francisco departs an hour and half later at 09:50AM> We are checking all baggage except a couple very small carry-ons straight thru from Basel to San Fran. Will we have to go thru customs and security at Schiphol to change flights, and if so, is 1hour 30 min enuf time? I booked this flight as normal connecting with KLM. Thanks for any advice!!
