This isn't correct. The earliest the flights will resume is May 17th.

The Hong Kong Govt. via leader Carrie Lam, announced UK flights can now resume. Further details will be announced later today in a press release.

It is now up to the airlines to get prepared. While passenger flights can resume shortly, there is a matter of resolving what happens to UK-inbound aircrew who cannot enter Hong Kong without undertaking 21 day quarantine for now - the rule needs to be changed for this to make flights more straightforward rather than double crewing + extending duty.

That's not correct either.
First the official announcement has to be made. I understand that airlines have already been notified.
Then the airlines have to schedule their crew given the very strict quarantine requirements.
BA has to get an additional FA crew who will stay onboard during the short turnaround in HKG. The F cabin is dedicated as rest area for the two crews.
CX has to find crews who will engage in their complicated rotation.
I don't know for VS.

But CX is already selling tickets from 14 May, with 5 weekly flights.

last week CX was selling flights for this week from LHR. But guess they were removed.

Can’t find any references in reports of Carrie’s address today or the press release yet.

I just found this online (it's in Chinese)
https://www.info.gov.hk/gia/general/...1050400797.htm

It stated that HK residents in UK and Ireland can enter Hong Kong from 7 May onwards if things are not drastically worsened. It also shows some more information on the risk group classifications.

It's official. Flights now operating from 7 May for HK residents or those with specific entry visas approved by the HKG duty immigration officer at time of check in.
