This routing crosses more disrupted airspace than some southern alternatives through the Arabian Peninsula, but has fewer active conflict zones than northern paths through the Caucasus. Alternatives exist if Istanbul's airspace situation worsens.

Frankfurt to Istanbul uses standard European routing with no advisory exposure. Istanbul to Delhi routes via Iran/Pakistan with only peripheral level-1 exposure.
Pressure score 77 vs 43 for the direct option — a 34-point improvement by avoiding the advisory zone.
Hub dependency at Istanbul introduces connection risk; mitigated by strong Lufthansa–TK connectivity.
