Transit Visa
Hi
Yes, you do need to take a transit visa in many European countries that includes, Germany, UK, France etc.
Note that the transit visa is required if your stay in the airport is 6 hours or more, before you connect to the next flight irrespective of the destination (in your case it being India, but the transit visa is required even if there is halt say in Dubai).
The exception is Amsterdam (Schipol Airport) where you do not need a visa irrespective of the length and time of stay at the airport before you get on to the next flight to your destination.
You can always check out the Websites of the airline you are travelling (assuming it is Lufthansa) regarding the visa requirement and always call them at their 800 number for the latest information and updates
Hope this helps, else drop a line in the forum. Good luck on your trip
