Does anyone know if it’s possible to check-in an additional bag at IST when IST is just a stop (with your other bags checked to your final destination)? I will be travelling ORD-IST-MUC with 23 hours in IST w/ my wife. Were planning on doing some shopping in IST during the stopover and then checking in an additional bag at IST to MUC (in order to avoid too many carry-ons). All flights in TK C, and I have a star gold card. Would that be possible? I have done this once before at BKK, but it was a long time ago and not with TK.
