The current fare filings have fare basis code PQA72SNC and cover the holiday periods from Halloween through Easter (although clearly too late for the Halloween dates at this point). Travel validity dates from fare rules are below. These will generally pop-up when you do a Google Flights search (LAX-MUC below). They don't have a fare filing yet that covers holiday periods beyond Easter, so it's too early to be looking to book those.
