Can someone tell me why the flying hours between Hong Kong and London are different?

Hong Kong to London
flying hours (over 13 hours)

London to Hong Kong
flying hours (11- 12 hours)

Is it because of

Earth rotation?
Wind (headwind vs tailwind)?
The flight path are different?
Or else?

Please help. Many thanks.

Actually, you have already got the answers.

Yes. The earth rotation, wind direction and flight path will be the key factors for the flying time. Moreover, the aircraft type, airport and landing time are also the factors.

Different aircrafts will have different maximum speed. Boeing 747-400 will be faster than Airbus 340-300.

Some airports such as Narita Airport will have a longer queue for landing compared with other airports so more time is needed. Macau Airport will have a comparatively shorter landing queue to the one in Hong Kong.

If the landing time is within the peak time of the airport, more time is needed for the long queue.
