Why was my COVID extension denied at Chaeng Watthana immigration without a flight ticket?

A user reported their experience while attempting to renew their COVID extension at Chaeng Watthana immigration. They were denied due to not having a flight return ticket, despite having all other necessary documents. Comments from the community revealed that this situation may vary in how it's handled by immigration officials, with some users suggesting that proving plans to leave Thailand, such as by holding a booked ticket, is becoming increasingly necessary. Others noted that they had successfully obtained extensions without such documentation, indicating inconsistency in the processing of extension applications.
