Which Airlines Fly Delhi to Singapore?
Four carriers currently operate direct flights between Indira Gandhi International Airport (DEL) and Changi Airport (SIN), giving travellers a genuine choice between full-service and budget options. Singapore Airlines consistently scores highest on punctuality for this sector, while IndiGo and Scoot attract price-sensitive travellers with stripped-back fares.
IndiGo
IndiGo runs multiple daily frequencies between Delhi and Singapore, making it the easiest carrier to find a seat on at short notice. The airline operates narrow-body Airbus A321neo aircraft on this route. Fares are competitive, and the punctuality record is strong for an LCC on an international sector.
Air India
Air India offers a full-service experience with complimentary meals and checked baggage included in most fare classes. The carrier typically operates the route with wide-body aircraft. For travellers who want extra comfort without paying premium business-class prices, Air India’s economy offering on this route is solid value.
Singapore Airlines
Singapore Airlines is the flag carrier of Singapore and regularly ranks among the world’s top five airlines (Skytrax World Airline Awards, 2025). Economy fares are higher than Indian LCCs but the in-flight product, including meal quality and seat pitch, is noticeably better on long sectors.
Scoot
Scoot is Singapore Airlines’ low-cost arm and focuses on pure price competition. Fares can be the cheapest on the route, but extras like meals, seat selection, and checked baggage cost more when added individually. Best suited for light packers who are flexible on timing.
What Is the Typical Flight Duration?
A non-stop Delhi to Singapore flight takes approximately 5 hours 30 minutes. The return leg (Singapore to Delhi) is slightly longer at around 5 hours 45 minutes due to prevailing winds. Connecting flights via hubs like Kuala Lumpur, Bangkok, or Colombo add 3-8 hours to total travel time depending on the layover.
What Are the Typical Fare Ranges for 2026?
Return fares on the Delhi-Singapore route vary significantly by season. According to HappyFares booking data compiled across Q1 2026, the fare windows below are representative but not guaranteed — prices shift daily based on demand.

When Is the Best Time to Book Delhi to Singapore Flights?
Research by the Airlines Reporting Corporation (ARC, 2024) found that international travellers booking 6-10 weeks in advance save an average of 24% compared to those booking within two weeks of departure. For the Delhi-Singapore route specifically, our experience shows that booking 6-8 weeks out hits the sweet spot between seat availability and fare levels.
Avoid booking during the first week after airlines open their schedules (typically 11-12 months out) unless you need a specific date. Fares often dip again 8-6 weeks before departure as airlines try to fill remaining seats.
Cheapest Months to Fly
January and September are historically the cheapest months for this route. Summer school holidays (May through July) and the Christmas-New Year window (mid-December through early January) see the highest demand and fares. If you can travel in September or early October, you’ll typically find the best value.
Cheapest Days of the Week
Tuesdays and Wednesdays consistently offer lower base fares on this route. Friday and Sunday departures are the most expensive, driven by weekend leisure travel demand. Even shifting departure by one day can save ₹3,000–₹8,000 on a return booking.
Travel Tips for Delhi to Singapore Flights
[PERSONAL EXPERIENCE]
- Visa: Indian passport holders need a Singapore visa. Apply online through the Singapore Immigration and Checkpoints Authority (ICA) website. Processing usually takes 3-5 working days. Fee is SGD 30 (approximately ₹1,900). Many travellers get approval within 48 hours.
- Baggage on LCCs: If you’re flying IndiGo or Scoot, add checked baggage at booking — it’s always cheaper than paying at the airport. A 20kg bag added at booking costs roughly half the airport rate.
- Transit at Changi: Singapore’s Changi Airport (regularly voted the world’s best airport) has excellent transit facilities. If your onward connection is with the same airline group, you usually don’t need to collect luggage.
- Currency: You cannot exchange Indian rupees directly in Singapore. Carry USD or exchange to SGD at good rates in Mustafa Centre (Little India, Singapore) rather than at the airport money changers.
- Seat selection: On Singapore Airlines, window seats on the left side (A seats) face towards the coastline on approach — worth selecting if you’re a first-time visitor.
- Travel insurance: Medical costs in Singapore are high. A comprehensive travel insurance policy covering at least USD 1 lakh (approximately ₹85 lakh) in medical expenses is strongly recommended.
Frequently Asked Questions

Which is the best airline for Delhi to Singapore?
This depends on your priorities. Singapore Airlines offers the best in-flight product. Air India provides a full-service experience at competitive fares. IndiGo and Scoot are the cheapest options for price-first travellers. All four airlines operate direct flights, so you have genuine choices.
What terminal does IndiGo use at Delhi airport?
IndiGo operates from Terminal 2 (T2) at Indira Gandhi International Airport for most international flights. Always verify the terminal on your booking confirmation, as terminal assignments can change during schedule updates.
Can I carry Indian food on Delhi to Singapore flights?
Solid home-cooked food in sealed containers is generally permitted by airlines. However, Singapore has strict biosecurity rules — do not carry fresh fruits, vegetables, or meat products into Singapore, as fines can be substantial (up to SGD 10,000). Packaged and commercially produced food items are usually fine.
Is it cheaper to book a one-way or return ticket?
Return tickets are almost always cheaper per leg than two separate one-way bookings on international routes. This is especially true for full-service carriers. The only exception is when you want maximum flexibility for the return date — in that case, a refundable one-way may make sense despite the higher cost.
What is the baggage allowance on Delhi to Singapore flights?
This varies by airline and fare class. Air India and Singapore Airlines typically include 23-30kg checked baggage in economy. IndiGo and Scoot charge separately for checked bags — a 20kg bag usually costs ₹1,800–₹3,500 when added at booking. Always check your specific fare conditions before travel.
