Airlines across the world have suffered revenue losses exceeding approximately $6.3 billion (PKR 2.15 trillion) after nearly 9,500 flights were canceled over four days at seven airports in Middle Eastern countries, aviation sources said.

Cancellations involving Pakistan alone have surpassed 400 flights, resulting in estimated losses of around $29 million (PKR 10 billion) for carriers operating from the country’s international airports, according to the sources.

The situation at Karachi Airport highlights the disruptions on the ground. Five foreign airline aircraft have remained stranded at the airport since February 28. Out of 14 foreign planes initially on site, nine have returned to their respective destinations.

The remaining aircraft include two from Air Arabia, two from Fly Dubai, and one from Qatar Airways. The delays are attributed to technical landings, diversions, and rerouting caused by the regional tensions.

Officials warned that if the situation in the Middle East worsens and air operations are not restored, airline businesses could come to a near standstill.

In addition to lost ticket revenue, carriers are facing heavy financial pressure from passenger refunds and additional accommodation costs caused by the widespread flight cancellations.

Aviation sources emphasized that the ongoing disruption is dealing a severe blow to airline operations and could have longer-term consequences if normal flight schedules are not quickly resumed.
