Flight time, distance and routing
Nonstop Delhi → Colombo is about 3 hours 35 minutes for roughly 2,400 km, tracking south down the length of the subcontinent and across the Palk Strait. The return CMB → DEL leg is similar. There is no time difference — Sri Lanka and India are both on UTC+5:30 (India IST; Sri Lanka SLST), so no jet lag at all on this route.
Best time to book and seasonal fares
Sri Lanka's west and south coasts (including Colombo) are driest and busiest from December to March, which overlaps Christmas, New Year and the Indian winter holidays — the priciest window. The May–September southwest monsoon brings lower fares to Colombo (while the east coast stays dry). The cheapest months are usually May–June and September–October.
Book 3–6 weeks ahead off-peak and 8–12 weeks for the December–February high season. We don't quote fixed fares — check live prices in the FlightGPT search.
How to get the fare cheaper

- Search 3–5 dates; midweek departures are typically cheaper than weekend ones.
- If you're visiting the east coast (Trincomalee, Arugam Bay), travel in the May–September window when Colombo fares are lowest and the east is dry.
- Travel light to access the cheapest fare buckets on IndiGo and SriLankan.
