Greater Bay Airlines has suspended most of its flights between Hong Kong and Bangkok for more than four months amid surging fuel prices driven by the conflict in the Middle East.

The airline’s website showed that as of 8pm on Thursday no flights were available between Hong Kong and Bangkok for most of the dates between May 12 and September 22.

The carrier said it had adjusted its services due to rising fuel prices and apologised to affected travellers.

“Due to the continued rise in fuel prices and the constantly changing market environment, and based on business considerations, Greater Bay Airlines has made short-term adjustments to services on certain routes,” it said.

“We will proactively contact the affected passengers and make appropriate arrangements to minimise any inconvenience caused to them. Greater Bay Airlines sincerely apologises to the affected passengers.”

The US-Israel war on Iran has continued to affect airlines, with oil markets remaining volatile since the conflict broke out at the end of February and led to the effective closure of the Strait of Hormuz, through which 20 per cent of the world’s oil supply passes.

Thailand is facing an oil supply crunch as the stand-off over the strait drains its reserves, with some petrol stations closed and fishers sidelined while being unable to afford the diesel to head out at sea.
