This routing scores in the middle range for this corridor because it crosses Iranian airspace constraints. Alternative routings may avoid this zone entirely, while some others may pass closer to the Ukraine situation.

  • 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.
