As a boy growing up in India,I had longed to travel abroad. I used to listen to the stories my father would tell me about his stay in Canada and tours to Europe in the 1970s’ with great interest.

My big moment finally came in the summer of 1998 when I was able to accompany my parents to Europe,where my father was to attend a meeting. 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. The flight was really smooth and thoroughly enjoyable,even for someone like me,who is otherwise scared of flying.

After spending almost two weeks in Europe,we took the Lufthansa airport express from Dusseldorf to Frankfurt airport for our return flight. What a journey that was! All along the Rhine (莱茵河),it was simply an unforgettable experience. I was in a sombre mood on the flight back to Mumbai as it marked the end of a wonderful vacation,but the Lufthansa crew members were able to change it into a most enjoyable experience yet again,with the quality of their service.

Being the first airline to take me overseas,Lufthansa will always hold a special place in my heart. Even today,I continue to enjoy flights on Lufthansa and simply cannot dream of choosing any other airline. Flying,in general,for me,has always been an ordeal (terrible and painful experience).Flying on Lufthansa,however,is something I always have and always will look forward to.
