After the Riyadh attack... what awaits travelers from Beirut?

The attack on King Khalid International Airport in Riyadh led to the cancellation of Middle East Airlines' morning and evening flights between Beirut and Riyadh, forcing travelers to reschedule their bookings. According to the official departure schedule of Rafic Hariri International Airport, flight ME424 at 08:15 and flight ME422 at 17:35 were listed as "cancelled." Saudi Arabia's General Authority of Civil Aviation said the attack killed 12 people and wounded 309, while 271 departing flights were cancelled at Riyadh airport, about 73% of that day's scheduled flights. Travel agency owners advised passengers to contact the issuer of their ticket before buying a new booking and to check onward flights, while the U.S. mission in Saudi Arabia urged its citizens to avoid King Khalid airport and its surroundings.
