My daughter holds both Thai and UK passports. She will soon be visiting the UK and I want to confirm that I have given her the correct instructions.

 

In BKK check in using UK passport.

At Thai immigration show Thai passport.

Enter UK with her UK passport.

 

When returning it would be the reverse procedure.

 

Thanks for your help

Confirm.

 

 

Actually, for the avoidance of doubt, it would be the same. In and out of Thailand on Thai passport and in and out of UK on British passport. 

 

Check in Thailand and UK with British passport. 

Confirm.

So in the UK you don't check in with Thai passport?

No- in and out of UK on Brit passport, out and in of Thailand on Thai passport. Perfectly legal.

If the British passport has been used for API (Advance Passenger Information) with the airline, there is no necessity to show both passports. 

Last time I flew from Bangkok, with my dual nationality daughter, Emirates asked to see her Thai passport aswell. 

 

The reason was that my daughter's UK passport is blank and thus has no Thai arrival stamp. They said that Thai immigration would not stamp an exit stamp in a blank passport with no sign of an entry stamp.

 

I would never offer both passports without being asked first, no need and no point.

Emirates have always asked for both passports when I travel with my son, it's there responsibility to ensure you have the correct paperwork.
