Not sure why you think you're getting car from plane. That only happens when you're arriving plane gets assigned to a remote stand, something which is far from guaranteed.
I’m arriving from ewr with the 747-8. I’m assuming that size of the plane will park by the gates and not by a remote stand. That being said I deplane regularly exit the terminal and go to FCT?
Both
That's only true, at least officially, if FRA-MUC is same day as MUC-JFK.
Great. Assuming remote stand will I get picked up in FRA?
Does they serve KSML in the FCT? If yes, from whom?
Yes (FCL as well)Same as on the plane (Sohar)
Which hechsher?
There's an entire thread dedicated to that.
how is the business lounge in muc?
Extremely packed, nothing special, has showers, not sure what other info there is to share.
I think Amex Plat can get you in to Senator lounge which is slightly better
