Forgive the Newbie Question
I am considering purchasing a return UK-Germany ticket, but I only need to use the portion into Germany. The return airfare is substantially lower then one-way. What will happen if I do not show up for the return portion of the itinerary? Do I get a credit for the unused portion, or will German police suspect I'm in the country illegally. Worse yet, would I show up on a TSA list somewhere?
