To make any ticket modifications, my family and I went to the Air China Melbourne office. We received amazing service. The staff was professional, courteous, and patient. They heard our situation and gave us the best help they could. Having someone to talk to in person made a big difference. The office was easy to find, and the interior was quite clean. The crew even gave my kids a warm wave and a grin. Despite its smallness, it gave us a sense of welcome. We left in a happy and satisfied state of mind.
