As for a time limit -- I'm not aware of any, but the longer your transit, the more askance the originating airline is going to look at your itinerary. Anything over 24 hours would make MUC a stopover, and then it would be upon your powers of persuasion to convince the airline employee that your plan was to hang out airside at MUC for multiple days.
I do understand the allure of taking the long way around, but In this case there have got to be many better options.

You're talking 15,000 km vs. 5,000 km, and with no ability to enter the transit country you're going to be raising red flags the whole time.
Agreed -- although OP won't be traveling UA, the TIMATIC system that this queries is used globally.
Got it, thank you so much! Then it should be safe then.

So the MUC-HND was part of award route. meanwhile DEL-MUC will be revenue fare. Assuming both segment served by LH, will LH help to merge it into one single ticket, plus tag along my luggage, in order to not collect my check-in luggage while in MUC. Or after all, whatever airlines I take to get me into MUC, in the end it will be the agent from DEL, would like to help tag all the way trough or not?
