Wasn’t able to check bags through to final destination BCN due to very messy itinerary AAL/AMS/OTP/IST issued by KLM containing a Tarom flight operated by TK) and felt lucky even to receive my bag on the belt in IST since gate staff in OTP informed me it might not be loaded to IST because I hadn’t contacted the transfer desk on arrival in OTP (no one told me to and the bag was tagged to IST so not sure what the issue was).
According to TK ground staff in the baggage area in IST, it was
not possible to check in my bag for the following day’s flight to BCN. If someone else has a different in-person experience, would you mind sharing how this is done?
