I checked in for my scheduled flight at 1030pm on 12 Jun 2021 for 0115 flight. At first the Qatar airlines staff announced that the flight will be delayed. So we waited. After 8 hours of waiting the staff finally announced that the flight got cancelled all together. I was rebooked for a flight that is to leave 24hrs later. No accomodation/food or any other assistance provided. The airlines shamelessly let us stranded on the airport. My original connecting flight was 4.5 hours later in Doha but rebooked connecting flight wasn't for another 9 hours. Everything was an ectremely painful experience. I will never fly with this airlines.
