Got a response from LH:
Dear [BenjaminNYC],
Greetings from Lufthansa!!
As you are a First class passenger, the Jet Airways staff has to guide you to the lounge and the douments will be collected by them and handed over to Lufthansa.After check-in the Lufthansa staff will hand over the boarding pass to you in the lounge.
Regards
Lufthansa German Airlines
To which I replied:
Thank you for your response. I have one further question: Will the Jet Airways staff be aware of their duties to guide me to the lounge?
Thank you again,
[BenjaminNYC]
To which they replied:
Yes.They handle transit passengers and are aware of the procedures.

Lufthansa German Airlines
