Why book

Avoids the warning area entirely — NRT–DEL routing via Singapore. The NRT–SIN leg routes south through Southeast Asian airspace — clean throughout. The SIN–DEL leg tracks northwest over the Indian subcontinent. Singapore Airlines operates both legs. Longest routing at ~10.3h; preferred when both Central Asian advisories and northern alternatives carry elevated notices.

The catch

Very few backup paths if this route is disrupted

Worth knowing

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