Best for

Use as a contingency when Central Asian corridor is restricted. Avoids the bottleneck entirely but adds Middle East airspace exposure and roughly 2 hours.

Weakness

First or second leg crosses the active Middle East advisory zone

Watch

This option's value depends on whether Gulf escalation stays contained. If it doesn't, the relative advantage of avoiding Central Asia disappears while you take on Middle East exposure. Monitor both situations.
