Not Verified | I will never be flying with BA again. This is my first and last. I was flying from Singapore, transit at Sydney and then to Auckland, my destination. Firstly, there was an hour delay for the flight from Singapore. That was fine, I received an email in advance and could just head over slightly later. I confirmed with the staff at Singapore that I'll make it just fine for my connecting flight since it was just an hour delay vs a few hours in transit. I arrived in Sydney, the flight was fine and the BA staff were decent. I knew that it was close to my boarding time and so I rushed through the checks to get to my international transit flight. We were ushered downstairs to catch the shuttle bus. After queuing for such a long time, they scanned my boarding pass and said that I was taken off this flight (I was not notified prior) and had to find the transfer desk and request for a re-book of my connecting flight. I rushed over as quickly as I could to waste no time. The lady who was a Qantas rep told me that I needed to speak to a Menzies rep about this matter. She gave me instructions to find a Menzies rep. I rushed to the boarding gate of an Asiana flight to speak to a Menzies rep but they were busy boarding the passengers. So, I waited by the side for all the passengers to board, only to be told to head to another transfer desk to re-book my connecting flight. There were other disgruntled passengers when I arrived. The next available flight was at night. This meant that I arrived at 8+am at Sydney and had to wait for close to 12 hours to get on the next flight. As I did not have an Aussie visa (did not need one as per my booked flights), I was not granted a day stay and was given a meal voucher and was sent off to hunt for a good place to rest/sleep/nap. Many cafes and restaurants rejected my meal voucher by the way but I finally got food. Ultimately, my re-booked flight was delayed again by another 30mins. The stress, anxiety, fatigue and hassle caused by BA's poor re-booking system. I've filed a formal complaint and request for compensation and we're waiting to hear back.
