Cathay Pacific Airways has postponed the resumption of direct flights to the Middle East amid signs of renewed escalation in the Iran crisis.

The airline said on Friday that daily passenger flights to Dubai in the United Arab Emirates would now resume on October 25, while its four weekly services to Riyadh, the capital of Saudi Arabia, would restart on October 26. Earlier this month, Cathay had said it intended to resume passenger services to both destinations on September 1.

Affected travelers will be offered the option to rebook, change their itinerary or receive a ticket refund.

Cathay also scrapped its previous plan to restart cargo services to Riyadh on August 1, without announcing a new date. “Cathay Cargo will assess when to resume the service,” the airline said. “Cathay will continue to monitor developments in the Middle East.”

Cathay Pacific has suspended its Middle East operations since March following the war waged by the United States and Israel against Iran. The conflict also disrupted oil supplies and drove up prices, triggering a global oil crisis.

In March, Cathay announced that it would double its fuel surcharge. As a temporary measure, it also changed its policy to review surcharge levels every two weeks instead of monthly.

Shortly before the conflict began in late February, Cathay’s one-way fuel surcharges stood at HK$142, HK$264 and HK$569 for short-, medium- and long-haul flights, respectively. They subsequently rose to HK$389, HK$725 and HK$1,560.

Earlier this week, the airline announced its latest surcharges: HK$165 for flights to mainland China, HK$448 for destinations in South Asia and HK$965 for long-haul services.
