Why book

Avoids the warning area entirely — DEL–NRT routing via Singapore. The DEL–SIN leg routes south over the Indian subcontinent, entirely avoiding Central Asian airspace. The SIN–NRT leg tracks northeast through Southeast Asian airspace and the South China Sea — also fully clean. Singapore Airlines operates both legs. Longest routing at ~10.2h total; preferred when both Central Asian advisories and northern South China Sea routing are elevated.

The catch

Very few backup paths if this route is disrupted

Worth knowing

The whole Delhi to Singapore to Tokyo route is clean. Singapore Airlines runs both parts often, so connection times at Singapore are usually comfortable.
