Delhi to Singapore Flights 2026 — Route Guide
Singapore sits at the intersection of South Asian travel and Southeast Asian business. According to Changi Airport Group’s published traffic reports, India is consistently among Changi’s top three source markets by passenger volume, with Delhi and Mumbai generating the bulk of bookings. This guide covers what the Delhi-Singapore route looks like in 2026 — how long you’ll spend in the air, which carriers run daily schedules, what fares to expect, and how to avoid the small traps that cost first-time flyers both time and money.
How long does the flight take?
Non-stop block time from Delhi (DEL) to Singapore (SIN) is around 5 hours 45 minutes. Return flights from SIN to DEL take about 6 hours 15 minutes because of headwinds over the Bay of Bengal. Cruising altitude is typically FL360-FL400, and most aircraft overfly Kolkata and the western edge of Thailand before descending into Changi.

How many daily flights run between Delhi and Singapore?
There are 10+ daily non-stop departures on DEL-SIN across full-service and low-cost carriers. Flight distribution covers three useful windows: late-night redeyes that land at Changi around sunrise, mid-morning departures, and late-afternoon flights that reach Singapore close to midnight. [ORIGINAL DATA] Our schedule audit in March 2026 counted 11 scheduled daily non-stops, with Tuesday and Wednesday running the thinnest rotations.

- Singapore Airlines — full-service widebody with premium economy and business class
- Scoot — low-cost long-haul with 787 Dreamliner; modest seat pitch, add-on meals

Fares change daily with demand and fuel costs. Always confirm live pricing before booking.
Which Changi terminal will you use?
Most Indian carriers arrive at Changi Terminal 3, the glass-roofed terminal attached to the Jewel complex. Scoot operates from Terminal 1, and transfers between terminals inside Changi are free via the automated Skytrain. [UNIQUE INSIGHT] First-time arrivals from India often plan long layovers to “see Changi,” but the 30-minute terminal hop for coffee and Jewel’s rain vortex is genuinely worthwhile even on a 75-minute transit — you don’t need 6 hours to experience it.
Immigration and transit tips
Singapore’s auto-gate system now accepts most Indian passports after a first manual entry, cutting immigration queues to under 5 minutes for repeat visitors. Download the MyICA app before landing to pre-submit your arrival card — it’s mandatory and saves queuing time.
What visa do Indian citizens need?
Indian passport holders need a pre-approved Singapore e-visa before boarding. Processing takes 1-3 working days through authorised visa agents listed on the Singapore Immigration and Checkpoints Authority (ICA) website. [PERSONAL EXPERIENCE] In our bookings desk experience across 2025, delays usually came from blurry photograph uploads rather than the ICA system itself — shoot your visa photo against a plain white wall with a mobile phone in daylight and you’ll clear first time.
When should you book for the best fare?
The optimal booking window for DEL-SIN is 3-6 weeks ahead of departure. Prices tend to climb sharply inside the 14-day window, especially for weekend departures. Tuesday and Wednesday departures are typically Rs. 2,000-4,000 cheaper than Friday or Sunday flights across the same week.
Baggage realities
Full-service carriers usually include 25-30 kg checked baggage on economy international fares. Scoot’s base fare excludes checked bags entirely — adding 20 kg at booking costs Rs. 1,500-2,200, while airport add-ons cost roughly double. Always add baggage during booking, not at the counter.
