Thai Spouse Holds USA and Thailand Passports

[Merwan]

I have booked a one way ticket to Bangkok for both of us from the USA.  Tell me if I am correct, please!

 

I will enter my spouse's  passport information in the computer using the Thailand passport information.  

Both passports will be submitted at the counter.  The Thai passport will be used at the gate and for entry into Thailand.

 

On the return the opposite will be done.  The information entered into the return flight's computer entry will be the USA passport.

Both will be submitted at the counter.  The Thai passport will be used to move through immigration out of Thailand.

The USA passport will be used at the gate and for entry into the USA.

 

Thanks in advance for your help.
