Hello,
It's me, again.
I contacted the airline, in this case Vietjet Air, to request an explanation as to why they denied me a boarding pass. Their response stated that I was denied due to being blacklisted by Thailand immigration, but they did not provide any proof. Of course I am dissatisfied with their response because, as I mentioned earlier, a reliable source informed me that I am not blacklisted.
Do you know where can I obtain official confirmation that I am not blacklisted by Thai Immigration? I have already sent an email to [saraban_imm@police.go.th](mailto:saraban_imm@police.go.th), but I have not received a reply.
If I have the confirmation, Vietjet is done!
Thank you.
TLDR : Answer Summary
An expat reported being denied a boarding pass by Vietjet Air, who stated it was due to being blacklisted by Thai immigration without proof. The individual has contacted the immigration office but has not received confirmation, wants to obtain an official letter asserting they are not blacklisted to challenge Vietjet's decision. The conversation includes others sharing their experiences with airlines and immigration, discussing potential legal recourses, and the challenges faced in confirming or disputing blacklisting.
