Why book

Reduces Middle East airspace exposure at the cost of a hub connection and 2 additional hours. Justified if current advisory zone escalation is your primary concern.

The catch

Goes close to a warning area but does not cross it

Worth knowing

IST–DEL second leg routes over Iran/Pakistan — level-1 airspace exposure. This is lower than the direct Gulf transit, but not zero.

Pressure score (77) is materially better than the direct option (53) because this routing avoids the Middle East advisory zone on both legs. Structural score is lower (63 vs 85) because of hub dependency and added complexity. The trade-off is explicit: less airspace pressure for more structural complexity.

Routing via Istanbul avoids the Middle East advisory zone on both legs: LHR–IST goes east via southeastern Europe, IST–DEL routes via Iran/Pakistan with only peripheral advisory exposure.
Pressure score advantage (77 vs 53) is the strongest argument for this option versus the direct flight — it reflects a meaningful reduction in current airspace exposure.
Adding a hub introduces connection risk: if the LHR–IST leg is delayed, you may miss the IST–DEL connection. Turkish Airlines' IST hub efficiency mitigates this but doesn't eliminate it.
Journey is approximately 2 hours longer than direct — 10.5 vs 8.5 hours. This is the structural cost of the pressure reduction.
Consider this option when UK FCDO or airline advisories flag elevated concern for the Gulf corridor specifically.
