Why book

Meaningfully reduces Middle East airspace exposure vs the direct option. Worth choosing if current advisory zone status is your primary concern.

The catch

Goes close to a warning area but does not cross it

Worth knowing

IST–BOM routes over Iran. Level-1 advisory — lower than Gulf direct, but not zero airspace exposure on the second leg.

Pressure score jumps from 53 to 77 by avoiding the advisory zone — a 24-point improvement. The cost is 2 extra hours and a hub stop. Mumbai is a closer destination than Delhi, which makes the time penalty more noticeable for LHR→BOM than for longer pairs.

Routing via Istanbul avoids the main Middle East advisory zone transit — both LHR–IST and IST–BOM routes stay outside the highest-severity areas.
Pressure score improves from 53 to 77 — a 24-point improvement versus the direct option, which is material.
Hub connection introduces standard risks: connection timing, missed-flight exposure. Turkish Airlines' IST operations are generally reliable.
Journey approximately 2 hours longer: 10.5 vs 8.5 hours. Same structural cost as LHR–DEL via Istanbul.
Consider this explicitly when UK FCDO elevates advisory severity for Gulf airspace or when airlines issue voluntary routing advisories.
