If you are flying domestically in Thailand, a new rule means the name on your boarding pass must match exactly how it appears in your passport. The regulation, introduced by the Civil Aviation Authority of Thailand, applies only to non-Thai passengers on domestic flights, according to a Phuket Express report.
The Tourism Authority of Thailand advises passengers to ensure they adhere to the new rule on identity verification. Boarding passes can be in paper format, as issued at airline check-in desks or self-service kiosks, PDF files emailed by airlines, or digital boarding passes stored on one’s phone in an app or email.
A screenshot of a boarding pass is not considered valid unless it has been verified by an airport barcode reader or scanner.
Foreign passengers flying domestically in Thailand are required to produce one of the following for identification purposes… an original passport, a UN Laissez-Passer, or a UN or government-issued travel document for refugees and asylum seekers.
In the event a passenger loses their ID document, airport officials will accept an emergency passport or travel certificate, a non-Thai ID card issued by the Department of Provincial Administration, or a Thai driving licence.
