Germany - Express line for Custom and security check FRA

Hi,
I will fly from FRA to USA. I heard the security check to US is tight. I have some questions as below.
Is there express line for custom and security check at Frankfurt Airport for LH Business class customer?
What is the beginning boarding time prior Departure from FRA to US via LH?
What time the LH gate close?
Thank you

You asked a similar question, which was moved to the Lufthansa Miles and More Forum.

I suggest you ask the new questions about closing time for gate etc. in this thread. Therefore I will not move this post over to the LH Forum but close it.

Thank your for your understanding
