1) This requires a slightly longer explanation, please bear with me. As a family of four, we redeemed our tickets over 9 months prior to the trip. However, even though we were redeeming so far in advance, we were only able to redeem two business class and two premium economy class seats. Please note that all the seats were redeemed with the same amount of points. As I am a Asia Miles diamond member, I assigned myself and one of my children to the premium economy seats and my spouse and the other child to the business class seats, hoping that with my higher member status we could get the extra biz class seats ahead of the trip. Unfortunately that did not happen. At the check-in counter we tried to upgrade the seats again but was informed that CX was not releasing any more seats for redemption, despite the fact that half the seats on business class were empty (and as it happens 2/3rd of the premium economy seats were also empty). At this point, I informed the staff at the check-in counter that we, as a family, would be swapping seats for the flight, which they confirmed would not be a problem. When we boarded the flight, my kids decided they wanted to sit together in premium economy to watch films together during the flight, so my wife and I took the biz seats instead. We informed the respective cabin crew members of this arrangement, which they confirmed was not a problem. So far so good. However, as we were about to take off, the inflight service manager approached and stated that because child tickets are cheaper than adult tickets, we could not unilaterally swap seats between biz and prem econ. Once I informed her that the tickets were all redeemed and for the same value of points, she begrudgingly left. However, once we were airborne, she returned again with her tablet containing CX regulations and claimed that although the tickets were of the same value, there is a CX rule that required an adult to be in the same cabin class as a child if that child is below 12 years old. My kids are 11 and 14. Not knowing enough about the specific CX regulations to challenge her on that and not wanting to make more of a scene and disturb other passengers, I was essentially booted out of my seat and had to swap back with one of my children. They were not pleased and nor was I. Upon landing, we immediately searched online and find that the rule she claimed was incorrect. Only parents of children under six needs to be in the same cabin class. For kids between 6-12 you just need to be on the same flight and not necessarily in the same cabin class. Please see the relevant clause below. When we challenged this in-flight service manager on this as we were disembarking the flight, she realised she had misquoted the rule and so went back to her original claim that adult and child tickets are different and we we could not unilaterally change seats and should have done so at check in. She was not at fault. Long story short. As customers who redeemed these flights with hard earned points and we felt mistreated

3) According to the crew this issue was already present on their outbound flight and the airport engineers claimed it was fixed but when the flight took off, the inflight system failed to work again and could not be fixed mid-flight. They even refused to provide us with complimentary WiFi and we had to pay for it ourselves. This was close to a 9 hour day time flight.

“Travelling with children

For their safety, child passengers aged between 2 and 12 years old travelling on a Cathay Pacific flight need to be accompanied by their parents or guardians (at least 18 years old) at all times. Children under 6 years old must travel in the same cabin class with their parents or guardians.”
