Hello:

I am flying from HKG-LAX on CX884 on 15 April. The flight time is listed as 13 hours, 25 minutes. The same flight on 29 March is only 12 hours, 35 minutes, almost an hour shorter. I did some checking a few days go and it appears flights in earlier parts of March were all listed as 12 hours, 35 minutes but from and after 30 March, the new flight time is consistently listed as 13 hours, 25 minutes.

How is it possible the flight time could vary so dramatically?

Thoughts?
