Thanks for the replies everyone, now I'm a lot more at ease =) There is one more question though...

I understand that the CO99 flight would most likely be full since there is only one of them each day, so what if we do miss the flight, and the next day's flight is full as well?? Can we be stranded for a few days straight until 2 spots open up? x_X Or can we request to be put on another airline's flight to HK that has spots if we really have to make it to HK on time for an important event?
