Direct nonstop flights from Toronto (All Airports) (YTOA) to Indira Gandhi International Airport (DEL) offer the fastest door-to-door travel (about 14–16 hours) and less risk of missed connections; however, they can be more expensive and are sometimes seasonally limited. Connecting flights through Doha, Dubai, Abu Dhabi, London, or Frankfurt often provide cheaper fares and more schedule flexibility, but add time and increase exposure to separate delays—particularly in January when fog in Delhi or snow in Toronto can disrupt legs. If minimizing travel time and complexity is a priority, choose nonstop; if saving money or using preferred frequent-flyer alliances is more important, opt for a one-stop routing. CTA: Compare total trip time, layover lengths, and price—book the option that best balances cost and convenience for your January itinerary.
