Also no security line for premium/elite pax, in a very new airport

Flying in LH Business, they will not have to wait for check-in.
And I have I never passed more than 10 minutes in the security queue at BCN. (But it's true that there is no fast track.

Also the LH flights to MUC generally leave from gates fairly close to security. So they really don't need to arrive more than 40 minutes before their flight (since check-in closes 30 minutes before).
I would tell them to be there 1 hour before the flight, and they'll have plenty of time for a drink in the Spanair / Star Alliance lounge. ^
