We arrived just in time to the airport in Taipei, checked in and passed the security to arrive exactly at the time when boarding should start. This was all quite fine, beside the long line on the check in counter.
But then we had to wait for a long time in front of the gate. It seems that a flight before us was delayed and caused our delay. In the end we arrived approx. 2 hours late in Wuxi and I am wondering why the did not just changed our gate (anyway they brought us to the aircraft by bus).
