Royal Jordanian Airlines has altered the route of its flights to Beirut in order to avoid flying through Syrian airspace.
Outbound services from Amman to the Lebanese capital will now divert to the south of Jordan, before entering Egyptain airspace and looping over the Mediterranean Sea.
The detour will result in flying times of 1h 45min compared with the previous duration of 1h, says Royal Jordanian president Amer Hadidi.
He adds that the move reflects the airline's "commitment to the safety of passengers and security of operations".
Royal Jordanian suspended its daily flights to the Syrian cities of Damascus and Aleppo last July. Other carriers including Saudia, Turkish Airlines and EgyptAir have also withdrawn from the country.
In September, rebel group the Free Syrian Army said it regarded any civilian aircraft operating out of Syrian airports as legitimate targets.
