How do you buy air ticket for indo helper who only has one name in her passport?

I have had to do via a travel agent. It is harder to make these bookings online. My first helper was Indo and she had only one name. Travel agents are aware of this and a lot of airlines in the region know this. Garuda is safest.

For example, u can try: First Name: Hayati Last Name: - Or First Name: Hayati Last Name: Hayati Still best to just double check with airline or TA

just put the same name for first and last name, but some airlines the current system already have option to tick if don't have last name

thanks
