I flew (with mrs-so3003) with CX from HKG-PEK last week, on a flight that arrived 5 1/2 hours late (CX 332 on 15th July, scheduled 1200-1525, actual 1715-2058). Is there any equivalent to EU261 compensation that we can claim for this significant delay?

Our "losses" due to the delay are difficult to define financially, but essentially we checked out of a club suite in HK hotel early in the morning to get to airport in sufficient time, without having been warned in advance of the substantial delay. We then arrived in our Beijing hotel far too late to enjoy any of the club lounge benefits we had paid for. Had I been warned in advance about the substantial delay I could have amended my hotel bookings to avoid booking a club room I couldn't ultimately use, and not have set my alarm so early in the morning of travel!

My internet searches have been unhelpful so far, but any suggestions here would be greatly appreciated
