Three carriers fly Delhi to Singapore nonstop. Singapore Airlines runs twice-daily services, deploying the A380 superjumbo on certain rotations alongside the B787-10 — its flagship product into its Changi hub. Air India typically operates multiple daily nonstops (B787/A321neo); note it is reducing DEL–SIN to around 14 weekly flights from 1 June to 31 August 2026 as part of network cuts. IndiGo flies a daily A321neo — usually the lowest fares.
Combined, the route offers roughly 4–5 nonstops a day. One-stop options via Bangkok, Kuala Lumpur, Colombo and the Gulf are also widely available.
Nonstop Delhi → Singapore is between 5h 35m and 6h 30m (around 5h 45m typical) depending on routing and winds, covering about 4,160 km south-east across the Bay of Bengal. The return SIN → DEL leg is similar. Singapore is 2 hours 30 minutes ahead of India (SGT UTC+8; IST UTC+5:30). Overnight departures land in Changi in the early morning local time.
Peaks are the May–July school break, December–January (Christmas/New Year), and the Singapore F1 night race in late September/early October. The cheapest months are usually February and the August–early-September shoulder.
Book 6–10 weeks ahead for off-peak economy and 12–16 weeks for December and the F1 weekend. With Air India thinned out in the June–August 2026 window, lock in the remaining nonstops early. Live fares are in the FlightGPT search.
Delhi (DEL) — international flights depart from Indira Gandhi International's Terminal 3 (T3). Singapore (SIN) — Changi has multiple terminals linked by the Skytrain. Singapore Airlines uses Terminal 3 (its hub); IndiGo typically uses Terminal 2; Air India is usually at Terminal 1 (verify on your boarding pass). All terminals are airside-connected for transit, and the Jewel complex sits between terminals.
Singapore Airlines and Air India economy typically include 30 kg checked + 7 kg cabin. IndiGo international 6E fares usually include around 30 kg checked + 7 kg cabin — see IndiGo baggage and Air India baggage for current figures. Premium economy and business carry higher allowances. Basic/promo fares can carry reduced baggage, so confirm your fare class before flying.
Indian travellers need a Singapore eVisa — there is no visa on arrival. You apply through an ICA-authorised visa agent or a Singapore mission in India, not directly as an individual. From 1 January 2026 the eVisa fee is around INR 2,100 per application plus the agent's service fee; processing is typically 3–5 working days. The SG Arrival Card is mandatory and free — file it on the official ICA portal within 3 days of arrival. A 96-hour Visa-Free Transit Facility may apply with a qualifying US, UK, Canada, Australia, Japan, NZ, Germany or Switzerland visa. Confirm current rules on the official ICA site.
Beyond the nonstops, one-stop fares route via Bangkok (BKK), Kuala Lumpur (KUL), Colombo (CMB) and Gulf hubs — useful if nonstop dates are tight or pricey. Changi itself is one of the world's best transit airports, so Singapore is also an ideal launchpad onward to Bali, Australia, Indonesia and the rest of Southeast Asia on a single through-ticket. Prefer through-tickets for baggage and connection protection.
Singapore combines Gardens by the Bay, Marina Bay Sands, Sentosa, a world-class zoo and a legendary hawker-food scene in one compact, ultra-efficient city-state — and it's a springboard to the rest of Southeast Asia. The climate is warm and humid year-round; the F1 night race in late September and the festive year-end light-ups are major draws.
