Is the K-1 Visa a Travel Document?

Hi everyone, sorry if this seems like a silly question because I've never had to deal with a visa before. 

 

But is the K1 visa considered a travel document?

 

I'm asking because for my flight check-in there's a field where I am able to fill in travel document information, should I fill that out?

 

Thanks again all.

Your passport is your travel document. Visa is document for US entry.

Your travel document is your passport, as mentioned above. Most airlines also ask for your visa information when checking in, but they should clearly ask for "visa" information. Your travel document is always your passport.

Alright, thanks every one!
