I've had no problem checking the site on 31st Dec 1999 and 1st Jan 2000, while Vancouver was still at 31st Dec 1999 time. I'm in Bangkok at the moment!
But lately something else is happening ...apparently a CP 747-400 aircraft (no.884) is 'stuck' in HKG and all the flights between HKG-BKK-HKG has been cancelled for the next 4 days. A few friends booked on those flights have been transferred to JL , CX and EK flights. Something about 'engine' problems. But if you check the timings of the CP8 flight returning from HKG to YVR, that flight has been pushed back to depart at 1900 meaning that CP is using the inbound aircraft from YVR arriving at 1830 to do a quick turnaround for the return flight. That means that the 'troubled' aircraft is still in HKG.
Anyway - just thought you should know...!
