Thailand has made transit visa mandatory for Pakistani passengers.
Prior to this, the visa was not relevant to passengers on transit basis. Thai Airways and other airline companies now no longer allow to provide boarding card to hundreds of Pakistanis.
This has incurred passengers who were set to travel via Thailand to switched to other airlines.
Thailand government has stated that the Pakistanis have to visit the embassy in person to attain the visa, which was previously sent to them by post.
