Hi, I am a regular Customer of Thai Airways All my flight schedule was changed. I managed by myself to change my flight otherwise I will be late to go to my work. My Flight TG3429 was delay 4 hours from Karachi to Bangkok. When I reached Bangkok my next flight was on 25th 17:10 - TG 475 Bangkok to Sydney. I have to wait 17 hours at Bangkok airport. When i asked to Airport staff what should i do they told me to contact to Thai Air Office and Thai Office was closed according to Airport Staff. Office will open again 5:30am. my question is when a customer have more than 12 hours stay Airline have to provide room and meal but all airport staff said they can't do anything and your office was close. 4 hours waiting in Karachi and 7 hours flight time then wait again 5 hours to meet a staff member to know what will be next step. And then wait again 12 hours.Now who is the responsible for all my expenses and time? Because since i start my journey from Sydney to Karachi and Karachi to back Sydney. Thai Airways keep changing the time of flight and days. And they informed me only once in the beginning when i was flying from Sydney to Karachi 8th March 2019. If Thai Air is not capable to run their operation as they gave me when i booked my flight. Then they should cancelled my flight and return my money rather than putting me in suffering situation.
