Q: Given a travel related situation, and given a specific question about the situation, summarize the question into a title
I have a flight with three segments, the first is from Bangkok to Cochin (India) with Thai AirAsia, the second from Cochin to Doha with Qatar Airways and the third from Doha to Frankfurt also with Qatar Airways.
Only the flight from Bangkok to Cochin has online check-in.

My question is, whether I can get my boarding pass for the flights with Qatar Airways already in Bangkok at the Qatar Airways booth. Because I don't have a visa for India, so I can't leave the transit area to collect my boarding pass at the regular check-in counters.

I didn't find my option in the answer of this post Where to obtain boarding passes when travelling with distinct airlines?

Also I didn't understand where the hotel agent in this answer came from or whether I can make use of this option: Can I get a boarding pass for a different airline in the transit area of Delhi Airport without going through immigration?

A:
When taking a multi-segment flight, is it guaranteed that you would get all boarding passes at the first airport?
