Flights London to Kolkata: Via Delhi or the Gulf, Flight Times and When to Book

Flights London to Kolkata Via Delhi or the Gulf Flight Times and When to Boo

There is no non-stop flight from London to Kolkata right now. Here is how to pick the best one-stop route home to the City of Joy, and when to book it. 

Quick answer: how do I fly from London to Kolkata? 
There is currently no non-stop flight between London and Kolkata, so every trip is one stop. Choose Air India via Delhi or Mumbai on one ticket (about 13 to 15 hours in total), or a Gulf airline via Dubai, Doha or Abu Dhabi (about 11.5 to 14 hours). For Christmas and the winter wedding season, book by late October. Our homepage shows no Kolkata fare today, but Delhi is from £303 per person, a fair reference for a via-Delhi routing. 

Is there a non-stop flight from London to Kolkata?

No, not at the moment. Air India’s last non-stop Kolkata to London service ran in November 2024, and we have found nothing scheduled for winter 2026–27. Every London to Kolkata journey is a one-stop trip, and the real decision is where you stop. One-stop routes give you more airlines, more departure airports and often a lower fare. 

Your route options from London to Kolkata

These are the one-ticket options we book most often. Journey times are typical totals including the stop. 

Route 

Airline 

Typical total time 

Good to know 

Via Delhi 

Air India 

About 13 to 15 hours 

Heathrow to Delhi non-stop, then a domestic hop on the same ticket. Many Delhi–Kolkata flights a day, so a missed connection is easier to fix. 

Via Mumbai 

Air India 

About 14 to 16 hours 

Slightly longer. Useful when Delhi seats are gone. 

Via Dubai 

Emirates 

About 11.5 to 14 hours 

Flies from Heathrow, Gatwick, Stansted, Manchester, Birmingham, Glasgow and Edinburgh. Dubai–Kolkata runs up to 12 times a week, with Premium Economy planned from late October 2026. 

Via Doha 

Qatar Airways 

About 12 to 14 hours 

Doha–Kolkata resumed in March 2026 (QR540). Lands in the small hours, so book a pick-up. 

Via Abu Dhabi 

Etihad 

About 12 to 14 hours 

Non-stop Abu Dhabi–Kolkata flights on sale through to February 2027. 

Via Singapore 

Singapore Airlines 

17 hours or more 

The long way round. Only if you want a Singapore stopover. 

What about British Airways, Virgin Atlantic and IndiGo? British Airways and Virgin Atlantic fly Heathrow to Delhi and Mumbai non-stop, but neither flies on to Kolkata, so you would need a separate domestic ticket and carry the risk if the first flight is late. IndiGo’s own UK long-haul flights are being wound down this autumn (Manchester ended in August and Heathrow–Mumbai is scheduled to stop around late October 2026), so we are not routing winter travel via IndiGo. 

Flight times and the time difference

Most London departures leave in the morning or early evening and land in Kolkata the next day. Kolkata is 5.5 hours ahead of the UK in winter (GMT) and 4.5 hours ahead in British Summer Time. A lunchtime Heathrow departure via Delhi usually has you in Kolkata by mid-morning local time. Gulf routes often arrive in the afternoon or late at night. On Air India via Delhi or Mumbai, you clear Indian immigration at your first Indian airport, so allow two to three hours for the connection. 

When to book flights from London to Kolkata

Kolkata fares follow the Bengali calendar as much as the UK school calendar.

Our advice 

Late October to November 2026 

High. Diwali, Kali Puja and the first wedding dates. 

Book now. Fly midweek where you can. 

Christmas 2026 and New Year 

Very high. Most schools break up on Friday 18 December and return on Monday 4 January. 

Book by late October. Leave a few days before 18 December or return after 4 January. 

January to early February 2027 

High on wedding dates, softer in between. 

Aim for the quieter days between the muhurat dates. 

February half-term to March 2027 

Medium, and Kolkata weather is at its best. 

Good value window. Book six to eight weeks out. 

Fares today: our homepage does not show a Kolkata fare, so we will not invent one. As a reference for a via-Delhi routing, Delhi is from £303 per person, checked 13 October 2026, prices change daily. Run a live search on manntravel.co.uk/flights or call us for your real fare. 

6 tips for a better London to Kolkata trip

1. Choose the stop that suits your family

A Gulf stop means about seven hours, a change, then about four and a half hours. Via Delhi it is around eight and a half hours, then a two-hour domestic flight. Families with young children often prefer the Gulf split. Older parents often prefer one Indian airline all the way. 

2. Give yourself a sensible connection

Ninety minutes is not enough with a late departure, an immigration queue and a terminal change. We look for two to three hours via Delhi and two hours or more in the Gulf. 

3. Fly midweek and avoid the obvious dates

Tuesday and Wednesday departures are usually the kindest on the wallet. The Friday before a school holiday and the Sunday at the end of it are the dates everyone wants. 

4. Book the return at the same time

A return booked together is almost always better value than two one-way fares. 

5. Live in the Midlands, the North or Scotland? Skip Heathrow

Emirates and Qatar Airways fly from Manchester, Birmingham, Edinburgh and Glasgow. For a family in Leicester or Glasgow, a Gulf routing from the nearest airport often beats the drive to Heathrow. 

6. Students and education staff: use MannPass

If anyone in your party is a verified student or works in education in the UK, Mann Travel Offer takes £25 off selected return flights between the UK and India. It is valid for 30 days, renewable, and cannot be combined with other promotions. 

Arriving in Kolkata: the airport and getting into the city

You land at Netaji Subhas Chandra Bose International Airport (CCU) at Dum Dum, about 17 km from the city centre. By road, allow 45 to 60 minutes. There is a metro option too: the Yellow Line’s Jai Hind (Biman Bandar) station opened at the airport in August 2025, with trains to Noapara for the Blue Line into the city. With wedding luggage, take a car.

Travelling with elderly parents? Ask us for wheelchair assistance at Heathrow, at the connection and in Kolkata. It is free, but must be requested in advance.

Documents. British passport holders need an OCI card or an Indian e-Visa. Apply only through the official Indian visa website, and check the UK government travel advice for India before you fly.

frequently asked questions

Is there a direct flight from London to Kolkata?

No. Air India’s last non-stop flight on the route operated in November 2024. All current options are one stop, via an Indian hub or the Gulf. 

About 11.5 to 14 hours via Dubai, Doha or Abu Dhabi, and about 13 to 15 hours via Delhi, including the connection. 

Via Delhi gives you one Indian airline and many onward flights. The Gulf gives shorter total journeys and departures from regional UK airports. 

By late October. Most schools break up on Friday 18 December 2026 and return on Monday 4 January 2027, and fares around those dates rise from now. 

About 17 km. Allow 45 to 60 minutes by taxi, or use the Yellow Line metro from the airport’s Jai Hind station if you are travelling light. 

Fares, availability and airline schedules change daily and depend on the airline, date and fare type. Always check live prices and the latest government advice before booking.
