I will be flying back to US from IST with KLM +Delta. Same PNR. We have an overnight 15 hour layover in AMS. Does anyone know if KLM at IST would checkin my baggage all the way to My final destination? I do plan to go out of Schipol and stay in a hotel overnight. Would be nice not having to carry all the bags and recheck again in the morning given all the chaos happening at AMS this summer.
