Hong Kong flag carrier Cathay Pacific Airways has further extended its suspension of all flights to and from the Middle East until the end of May, amid a regional conflict that shows little sign of abating. But the airline will increase flights to Europe starting next month to cater to surging demand. The airline has extended its suspension of Middle East routes at least four times since early March. It announced just last week that services would be cancelled until the end of April. In an announcement on Tuesday, Cathay said flights between Hong Kong and Dubai in the United Arab Emirates, as well as between the city and Riyadh in Saudi Arabia, would remain suspended until the end of May.“We are monitoring the situation closely and will remain agile in our response,” the airline said. “The safety of our customers and people guides every decision we make.”Affected travellers will be offered flexibility to rebook, reroute or cancel their tickets, Cathay said. According to its website, travellers who have purchased flights between Hong Kong and Riyadh up to June 30 can rebook, reroute or get refunds for their tickets without being charged with the usual administrative fees.
