We planned to travel to Belgium，Netherlands and West Germany.I have vivid memories even today of going to Mumbai airport at night all excited about finally going abroad. I had heard several great things about Lufthansa till then but now I finally got to experience them first hand during the flight to Frankfurt. We flew business class and even today I can remember the excellent service by the Lufthansa crew.

What a journey that was! All along the Rhine (莱茵河)，it was simply an unforgettable experience.
