This corridor has constraints due to airspace advisories in the region. Alternative routings further north or south may have fewer disruption concerns — compare options with your airline.
Routing via Istanbul avoids the Middle East advisory zone on both legs: London to Istanbul goes east via southeastern Europe, Istanbul to Delhi 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 London to Istanbul leg is delayed, you may miss the Istanbul to Delhi connection. Turkish Airlines' Istanbul 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.

Some
The Istanbul to or from Delhi leg crosses Iranian airspace directly. Iranian airspace restrictions can escalate this route's risk score.
This route's European flight leg tracks through Eastern Europe near the Ukraine conflict zone. If Ukrainian airspace status changes, route options on this corridor may be affected.
