Even if the two flights are on the same ticket and you checked in for both together, 'compensation' for a weather delay really is just to get you to your destination safely. They may get you a hotel and/or food (required in Europe, almost never get it in the US) but they don't owe you anything else as vouchers, cash, upgrades, miles, or anything else.

As for the taxes, I don't know much about HK airport tax, but ask whoever you bought the ticket from would be my guess.

You can say it is weather delay. But CA has flight that can depart earlier, KA has no airplane in PEK the evening of the day before, which they should have done. They may have very flight delay and maybe they cancelled the flight from HKG to PEK and every passenger in HKG had gone home that night so they do not want to fly a empty aircraft to PEK to pick up the passenger in PEK in the next morning. Whose problem should this be?

I called CX the evening the day before depature and asked them if the flight in the next morning has any delay and was told everything looks fine. I asked this since I saw the storm that evening. I registered the cell phone notification for the departure time. I arrived at airport at 6:50 and was told the flight will be delayed to 11:30am. The notification comes to my cell phone on 10:30am saying that the flight has been delayed. Ridiculous, yes!

This delay is still due to weather - if there were no thunderstorms this wouldn't have happened. Also, for weather delays they generally don't put you on another carrier.

As for the delay notification, they could have done better. The evening before they might not have know about the cancellation if the flight departed late, but they could have done a better job letting passengers know about it. If you think there might be a problem, actually calling them or checking their website usually works, but again, they should have done a better job letting passengers know what is going on.

Now it is time for me to comment on CX's bad customer relationship website. I submitted a complaint letter on CX's website. 30 days later( each of the passeneger's letter or follow-on reply needs to wait for 30 days to get a reply). I got the first round reply: they feel sorry for the flight delay and decided to reimburse my lodging for the first day. Plus, they will give me two upgrade voucher( I guess it will only be valid for KA short haul). They need me to send them the orginal hotel receipt for the first day.

I sent the hotel bill and several weeks after I got the second round reply: they did receive the hotel bill but can not tell from the bill that hotel charged me for the "no-show".

I submitted the complaint letter again: "You did not ask me to provide the no-show bill, the hotel usually does not provide such receipt"

I actually was not charged for the no-show although the cancellation policy says I need to cancel 24 hours before the arrival. I called the hotel when there is flight delay. I called a couple of times internationally for the possible delay and finally told them I will not be there that day.

My four-day holiday was shortened to 3 day. Why does CX need the no-show bill to give me compensation? I did not ask for the indirect loss I had with the flight delay.

For the Hong Kong departure tax, they feel they are not obliged to but they will provide 2XUSD25 voucher to me as a good will.

surely they wont - they did not take from you since you ticketed through LAN
but if your original flight was on the same calendar day and you still have the original itinerary, you can send it to HKCAD and you can get your HKD120 refunded. no idea in waht form tho - and i'm not sure if it's not too late.

Should be the issuing airline if on the same ticket. If on separate tickets, you can get a HKD120 cash refund at a HKIA counter in the departure check-in area by presenting both boarding passes and your travel document on the day of transit.

I tried to get refund at the airport but they only accept if two the boaridng passes are in the same day.

Yes, HKG has same day rule for tax refund, not 24 hours.@:-)

Sorry - you are definitely unlucky - the unfriendly sky is playing with your flights...

No compensation...
