Ranks second: same clean airspace as direct, but the Bangkok connection adds schedule risk and journey time. Thai's Delhi to Bangkok frequency makes it a viable backup when direct options are full.
Delhi to Bangkok first leg routes southeast over Myanmar — no advisory zone exposure on either segment.
Bangkok to Singapore is a high-frequency short hop (~2h). Thai Airways and other carriers operate this connection with strong daily departure options.
Bangkok is a well-established Southeast Asian hub with multiple onward connections if Singapore-bound flights are disrupted.
Adds approximately 1 hour versus direct due to the Bangkok connection geometry and layover.
Best used when direct Delhi to Singapore capacity is constrained or when a Bangkok stop fits your itinerary.
