Worth knowing

Monitor updates on Russian airspace status and Central Asian corridor congestion before departure. Confirm with your airline whether the routing may shift or incur additional costs if conditions change.

Closed areas · Flight options

This direct routing avoids crossing active conflict zones but sits adjacent to congested Central Asian corridors and Russian airspace restrictions. Alternative routings through the Middle East or Southeast Asia may offer more separation from these warning areas.

Airspace Low

The European part of this journey passes near the Ukraine conflict zone. If that airspace changes, the options on this corridor can change with it.
