Hi everyone

Want to ask on international to domestic transfer at IST on separate PNRs. I understand that there's that domestic transfer hall from international, but with separate PNR, do I need to go landside to recheck my bags or can I ask the check in agent to check through the bags to my final destination? Going to do CGK-IST-ESB but IST-ESB is on a different PNR and different cabin (J to Y)

Many thanks beforehand
