Middle East aviation crisis deepens as geopolitical tensions escalate. Over 21,000 flights have been cancelled across major regional airports since late February, leaving approximately 1.5 million passengers stranded. Dubai International and Abu Dhabi's Zayed International Airport, two of the world's busiest travel hubs, face severe operational disruptions following direct strikes on five airports across the UAE, Kuwait, Bahrain, and Iraq. The aviation industry has suffered estimated revenue losses exceeding $2.6 billion in just four days. Major carriers including Emirates, Etihad Airways, Qatar Airways, and Gulf Air have grounded most of their fleets, forcing airlines to absorb costs of free cancellations and passenger reschedules.
