I already got approved for the thai pass and then want to amend the departure date to leave a few days earlier.   The thai pass button that indicates you can amend your booking is closed off once the thai pass is approved so am guessing this means I have to complete a new thai pass with new supporting docs etc.  is this correct or am I missing something?  

You will have to apply for a new Thailand Pass unless the change is less than 72 hours.

Thanks Ubanjoe, so if original flight was Mar 9 and I change it to Mar 6 at the same time this seems to indicate there is no need to apply for a thai pass.   Is this correct?  I wonder if the airline will accept this.   If I also apply for a new Thai pass anyway for the revised date 3 days earlier will this just get bounced back as not needed?  Thanks.

When I went through the Thai Pass suspension on 22 Dec it was confirmed that the 72 hours is only after the original date, you cannot bring it forward like the OP has

 

This is confirmed on the Sydney Thai Consulate site

There has been mixed reports and interpretation of the the 72 hours.

Probably best to apply for a new Thailand Pass to avoid problems. It will be accepted.

Thank you both, I also just confirmed by calling the help desk that you can’t bring it forward to an earlier date.  Already re-applied.  Thanks
