In my posting, I never said there was a mutual exclusive relationship between bps and checking bags. Only that the bags CAN more than likely be checked through (depends on if TK and A3 have an interlining agreement and I didn't look that up AND both segments are on the same ticket). As for the BP. It also depends if it is one ticket or two separate tickets. If one ticket, and the OP uses TK online checkin, and their system cannot print the A3 segment, then the OP would have to use A3 online checkin just for that segment. However, currently A3 online checkin is only valid with both an A3 record locator AND an A3 ticket number starting with 390 AND travel has to start at ATH. So, without more information about the OPs ticket situation, we cannot give a more accurate assessment.
