Star Alliance - * alliance lounge access in FRA

I will be arriving in FRA on Thai first class from BKK; Departing to MAN on LH
business class. In other airports (LAX for example) I have been allowed access to a First Class lounge based on my boarding ticket from my incoming flight, not my departing flight. Will I be allowed into the LH first Class lounge in FRA?

Thanks folks,
Exbrit

You can only access LH First Class lounge on arrival at FRA if you arrive on LH metal in F. Since you are arriving on TG metal and departing on LH in C you'll only have access to LH Business lounges. The Pier B Business lounge re-opened recently and is said to be quite nice.

The business lounge in FRA is quite adequate but often packed.
