Singapore fares climb around the year-end holidays, the June school-holiday period, and major events like the Formula 1 night race in September. The quieter months of February–April and the post-summer window offer better prices. For this long connecting route, book 8–12 weeks ahead and compare a through-fare via Delhi with separately booked legs; a same-airline ticket is usually the safest value.
Expect ≈ 8–10 hours door to door with one stop. The Dehradun–Delhi hop is ≈ 55 minutes, then Delhi–Singapore is ≈ 5h 30m non-stop, plus the layover. Singapore is 2h 30m ahead of India, so you lose time on arrival. Allow at least 2.5–3 hours at Delhi for the domestic-to-international transfer, including a terminal change and immigration.
Singapore Airlines and Air India typically include 25–30 kg checked baggage on the international leg, while a low-cost Dehradun–Delhi hop may include only 15 kg — check the through-allowance.

You arrive at Singapore Changi (SIN), repeatedly rated among the world's best airports, about 20 km from the city centre and linked by MRT, bus and taxi.
