Lufthansa offers the option of booking multi-city itineraries, which allow you to travel to multiple destinations on a single booking. This is particularly useful when you plan to visit several cities during your trip. Keep in mind that my information is based on the situation as of September 2021, so I recommend checking Lufthansa's official website or contacting their customer service for the most current information and guidelines.

Here's how you typically book a multi-city itinerary with Lufthansa:

• Visit Lufthansa's Website: Go to the  Lufthansa  Multi City  official website and use the booking interface to start searching for flights.
• Select "Multi-City" Option: Look for the option that allows you to choose a multi-city itinerary. This option might be labeled as "Multi-City," "Multiple Destinations," or something similar. Click on this option to proceed with your multi-city booking.
• Enter Your Travel Details: Enter the details of your trip, including the cities you plan to visit, the travel dates for each leg of the journey, and the number of passengers.
• Search for Flights: After entering your travel details, the booking system will search for available flights that match your itinerary. You'll likely see options for each segment of your trip.
• Select Flights and Seats: Choose the flights that best suit your schedule and preferences for each leg of the journey. During the seat selection process, you can typically select seats for each flight if they are available.
• Review and Confirm: Once you've selected all your flights and seats, review the itinerary to ensure all details are accurate. Check the total cost of the booking, including any additional fees or charges.
• Complete the Booking: Proceed to the payment section to complete your booking. You'll provide your passenger and payment information to finalize the reservation.
• Receive Booking Confirmation: After completing the booking, you'll receive a confirmation email from Lufthansa containing your itinerary details, booking reference, and other important information.

Please be aware that the process and availability might vary based on the specific routes, dates, and current booking procedures of Lufthansa.
