I am from India. If I have single entry Thai visa and I go to Cambodia from Thailand, Can I travel back to India via connecting flight from Bangkok? Do I need a transit visa? There are no direct flights between Cambodia and India, therefore cannot enter Cambodia directly from India.
TLDR : Answer Summary
Yes, you can travel back to India via a connecting flight from Bangkok if you have a single entry Thai visa and are coming from Cambodia. However, make sure to check the transit visa requirements, as they may vary depending on your nationality and the specific airline.
