Hi. You will I got denied boarding yesterday with my daughter by Air France yesterday she is a UK and thai passport holder was taking her to Thailand to visit her mum.
13. It only cone in on the 17.10.2022. I had not heard of this and neither had checkin staff I have traveled with my daughter to Thailand over 25 times in the past.
The requirement only come in on the 17.10.2022 and the checkin staff were only Aware of this when they put my daughters details in to the system. They also showed me the screen and they were very helpful. Got letter from her mum and signed and stamp from lawyer in Thailand. They rebooted us on klm for today.
You will need to get a letter from both parents with there passport numbers and the children passport numbers and the person they are travelling with passport details and a copy of the parents passport must be with the letter signed by parents and stamped and signed by a lawyer. Not sure how long thailand will require this.
