After 3 weeks holidays in Thailand, we will return to Belgium with AirIndia.
There is a long stay at the airpost of New Dehli during the flight (13hours) so we would like to use that time and catch a glimpse of India.
The problem when I look about transit visas is that they are valid only 15days after being granted. So If I ask it in Belgium, it won't last until our return..
I wanted to know if it was possible to get this transit visas in Bangkok before our return flight?
If possible, how long does it take to get it? Where to ask? How much does it cost?
