Is an Onward Flight Enough for a Non-Immigrant ED Visa in Thailand?

It says copy of flight confirmation. It does not ask for return ticket.

But the airline may ask for one before allowing you to fly to Thailand.

A ticket departing Thailand to another SE Asia city should be OK.

There are cheap tickets to Vietnam as an example.
