Full breakdown →The top option stays clear of all warning areas.
The primary DEL–NRT routing tracks north over Pakistan and Kazakhstan before crossing Central Asia into Chinese airspace and then Japan. Air India, JAL, and ANA all operate direct service on this corridor. The route carries due to Central Asian corridor congestion and the Iran airspace proximity on the western segment near departure — the initial climb out of DEL briefly approaches the Iran and Pakistan airspace boundary. When Central Asian airspace advisories are stable this is the fastest option.
