Four active airspace restrictions — plus one congestion corridor over Central Asia — affect Europe–Asia flights today. See which routings cross the Iranian advisory zone, which stay clear, and how to compare them.
Four airspace restrictions currently shape long-haul routes between Europe, the Gulf, and Asia — plus a congestion corridor over Central Asia that adds its own delays. The restriction travellers feel most is the Iranian Airspace Advisory, which touches 65 of the routes we track. The hardest-hit corridor is Europe to India via Istanbul, where routings pass through the advisory area. On almost every affected pair, alternatives exist that stay clear of known warning areas — usually via Dubai or the Gulf corridor, or via East Asia hubs for routes where both Middle East options carry warnings.
These routes are most affected by the current Middle East airspace restrictions.
