I am treating the layover in Munich as an extra little vacation. I have never been there before, so 11+ hours is plenty of time to go into the city for a while. And now that I am aware of this free day room at the airport hotel in MUC it will be a nice place to stash my stuff. Although it sounds like the 6PM check out time is firm. So I will have a few hours less in town and more in the airport. But I guess I can kick back at the LH FCL to have dinner before the flight to BKK.

What class are you looking to book? Which FF program are you using?
