Hi everybody,
sorry, I'm new to this whole premium classes and lounge thing (employer has Y policy and only European clients

), so after fifteen years of collecting miles, I finally get to smell the air up front.
While it's probably not a once-in-a-lifetime-experience, I don't think I'll repeat that very often and hence I'd like to maximise the experience.
What lounges can/should I (no status except worthless FB silver

) use on departure, connection and arrival with the following flights:
FRA-ZRH-DXB in LX F - the FCT at FRA and FCL at FCL are obvious, but I didn't find anything about arrivals lounges at DXB.
FRA-DXB-FRA in LH (PrivatAir) C - again, the lounges at FRA and DXB respectively for departure are pretty clear, but what about using any facilities on arrival?
Thanks for your advice.
