Two crew members tested positive on November 20 and 27 upon their arrival in Hong Kong on flight BA027. One of them was sent back to the United Kingdom, whereas the other and their colleagues on the same flight have been sent to Penny's Bay quarantine center.

Due to strict quarantine requirements for crewmen on the same flights, the British airline decided to suspend its Hong Kong route to reduce the risk of staffers being stranded in Hong Kong.

“We have made the difficult decision to temporarily suspend flights to Hong Kong while we review operational requirements for this route,” it stated.

According to information on the Hong Kong international airport website, a BA027 flight to depart from Hong Kong to London at 11.45pm Sunday has been canceled.

Also canceled are BA028 flights on Monday and Tuesday. BA3591 on Tuesday afternoon is also axed.

At least five flights arriving from London operated by the same airline has been canceled so far, including BA3590 and BA027 on Sunday afternoon.
