Delta Air Lines stated that following several fatal attacks at Riyadh Airport, the company will postpone the launch of its direct flight route from Atlanta to Saudi Arabia's capital, Riyadh, until March.

Delta Air Lines originally planned to launch this route on October 23, using Airbus A350-900 wide-body aircraft. This would have been the first direct commercial flight between the United States and Saudi Arabia operated by an American airline.

According to FlightAware data, since Thursday, over 2,000 flights traveling to and from Riyadh's King Khalid International Airport have been cancelled. The Houthi rebels, supported by Yemen and Iran, claimed responsibility for these deadly attacks. The situation escalated further on Saturday when a missile struck the airport's passenger terminal, resulting in at least 12 deaths and more than 300 injuries, according to officials.

As of Monday, King Khalid International Airport remains closed.

Delta said in a statement: "We maintain close contact with the relevant governments and aviation partners, including Saudi Arabian Airlines and Riyadh Airlines, while continuously monitoring the development of the situation. Saudi Arabia remains an important market for Delta, and we are committed to serving this kingdom in the long term."

Delta Air Lines CEO Ed Bastian ( Ed Bastian ) stated to CNBC on Thursday that the company had not yet decided whether to postpone its maiden flight at that time.

He said, "Obviously, we are disappointed with the news that has occurred this week. Security will determine the final decision."

Before Delta made this decision, the Federal Aviation Administration (FAA) of the United States had already issued a warning to U.S. airlines on Sunday.

FAA indicates that pilots should exercise caution in Saudi Arabia "and its surrounding areas" due to "continuous military activities and navigation systems" posing risks to flight safety. In this warning, which is valid until December 10th, the agency states that these threats may pose potential risks to "aircraft at all altitudes."

Airlines have suspended flights to that airport, and some of these suspensions will continue throughout the rest of this week; some countries, including the United States and Australia, have also advised their citizens not to travel to that region.
