I actually booked a Lufthansa Express Bus and Rail & Fly ticket earlier this year when flying from Frankfurt to Nuremberg. The process was surprisingly smooth. When booking my flight on Lufthansa’s website, I just selected my final destination (Nuremberg) instead of Frankfurt, and it automatically added the train segment through Deutsche Bahn. The confirmation email included both my flight and rail details — no need for a separate booking. One tip: make sure you download your rail ticket from the “My Bookings” section before traveling. I once forgot and had to call Lufthansa’s support line to reissue it, but they handled it quickly. If you ever need to modify or cancel, the easiest way is through the Lufthansa Manage Booking page — it updates both your flight and rail segments instantly. Honestly, it’s super convenient for seamless city-to-airport connections.
