I traveled on BG389 from Bangkok to Dhaka on 15/06/25. At check-in, staff member Yudarath M was extremely rude and unhelpful regarding my passport, which was expiring in under 6 months. My family and I were left waiting for 45 minutes, and she refused to help or direct us to immigration. Her behavior was unprofessional and disrespectful. Your staff need better training in handling passengers with courtesy and care. I am a British citizen and have not been met with such indecency before. I will not be flying via this airport again if she or other disrespectful staff members are not held accountable for their manners and rude behaviour. When I asked Yudarath M how long it will take the airline manager to arrive to sort out my problem she said 20m. We had already been standing for 30m prior to that. When I went to ask her there are no seats how can we wait for 20m she gave me a dirty look and proceeded to say to walk around. Is this how a passenger deserves to be treated? She also kept talking over me when I tried to explain my situation whereby I have already travelled to Singapore Malaysia and Thailand consecutively in the past days and have spoken to their immigration officers regarding my expiring passport and I was not denied entry into those countries. But, she did not want to listen to me and told me to wait without listening to me. She described the situation to be “different “ to others, without explaining how. If I managed to gain entry into these countries (Singapore, Malaysia and Thailand), and travelled to Dhaka on 24/05/25, surely this situation cannot be “different” to others. She just wanted to create hassle. I also wanted to speak to the airline manager or immigration officer but she was not listening to me at all and was ignoring my family. Anyways, main point is I want your staff Yadarath M to be held accountable for her distasteful manners.
