A transit visa is not free. It might be worth it to pony up the little extra money and get a tourist visa for peace of mind. I would get the visa, but it's your call.

One thing to keep in mind is that you generally don't want to trust the governments of developing countries. If for whatever reason you are stuck in BOM, the passport control officer will show you no pity if you say that some embassy told you that you did not need a visa.

baa, don't worry bee happy

Even if you get it from the embassy in writing, signed, stamped, notarized, whatever, the immigration officer still might give you a hard time.

And even if they let you through in the end, that delay might cause you to miss your connecting flight. As the T&Cs say, you'll have to buy a walk-up ticket in that case.

The way 6E is trying to sell these 6th freedom tickets, it's probably easier and less stressful to book with someone else. And possibly cheaper too once you factor in visa, customs duty, possible walk-up ticket, etc. etc.:D

OK, just an update.

I have now checked with a supervisor with IndiGo customer service and they could confirm from the airport manager and management, that I do NOT need to worry about my luggage in Mumbai. Turns out section 10.2 applys to domestic flights and is not updated with regards to international flights.

They also gave me the number to IndiGo at Mumbai airport and I spoke with the staff and I was told I do not need to pick it up in Mumbai, but I will have to identify my luggage next to the staircase when boarding for Dubai. The plane I arrive on from BKK is actually the same plane that will take me to Dubai.

We'll see how it goes :)
