Do I need a transit visa for a self-transfer in Chennai while traveling from Thailand to Germany?

99.9% correct advise from a chennai resident and frequent traveller to Thailand and other places - You cannot do it. And don't do it. They won't even let you board in Thailand without an Indian entry permit. Unless you have an Indian e-visa and at least 4 hours time in between flights. Even then it is a very bad airport to do any transfer. Delhi Mumbai Bangalore Hyderabad Kochi are much better choices for Air Asia (still need visa). So don't try this. Go via dubai / middle east. Or for budget go via Singapore (scoot/air asia) then lufthansa. But still need to enter exit Singapore (free for germans / 3 hours min).

Be very careful with advice given by strangers on Facebook!

I doubt very much that AirAsia will check luggage through onto a Lufthansa flight!!!

You have obviously bought two separate flights which means that you have to pass immigration to be able to get your luggage and check it in for your flight to Germany.

I don't know wether a transit visa is available, otherwise you might need a tourist visa.

@Mae ******

you say "Self transfer". Those words indicate you will be picking up your bags and rechecking in with Lufthansa air. Therefore you will be going through immigration and need a visa

No need for a connected trip

No

2 seperate tickets have to collect your bag landside? Sounds like it, you will need a visa as you will go landside. This is why i never hop through India on budget airlines on route to SEA

As long as both flights are international flights, you can stay "airside" and not clear customs. There should be a transit desk to confirm your onward flight.
