India's Largest Airline
IndiGo carries more passengers within India than any other airline. The carrier launched UK services in 2025, connecting London and Manchester directly to India's major cities, with onward connections to Kolkata.
Boeing 787-9 Dreamliner
Long-haul flights operate on Boeing 787-9 aircraft leased from Norse Atlantic. The Dreamliner offers a quieter cabin, better humidity control, and larger windows compared to older aircraft types.
IndiGoStretch Premium Cabin
IndiGoStretch seats are arranged in a 2-3-2 layout with 43 inches of legroom. Passengers get priority boarding, extra baggage allowance of 30 kg checked and 12 kg cabin, plus complimentary meals and alcoholic beverages.
Complimentary Meals for All
Every passenger on UK routes receives complimentary hot meals. The menu features Indian cuisine prepared by Oberoi Flight Services. Vegetarian meals are the default, with non-vegetarian options available when pre-booked.
Generous Economy Seating
Economy Class on the 787 offers 31 inches of seat pitch in a 3-3-3 configuration. Each seat has a personal entertainment screen, USB charging port, and power outlet.
Strong Domestic Network
IndiGo operates over 2,000 daily flights across India. Passengers connecting to Kolkata benefit from short connection times and single-ticket booking through major Indian hubs.
Competitive Pricing
As a low-cost carrier, IndiGo typically offers lower base fares than legacy airlines. The UK routes include meals and baggage, making the total cost competitive with full-service competitors.
London Heathrow (LHR)
Fly to Kolkata via Mumbai or Delhi with IndiGo. Connect from London Heathrow Terminal 2 to India's hub airports, then onwards to Kolkata on IndiGo's domestic network.
Manchester (MAN)
Connect via Mumbai from Manchester to reach Kolkata. Same-terminal connections make the journey straightforward.
Economy Class
Economy passengers on IndiGo's UK routes receive 15 kg of checked baggage with standard fares. Cabin baggage allowance is one bag up to 7 kg plus a small personal item.
IndiGoStretch Class
IndiGoStretch passengers receive enhanced baggage allowance of 30 kg checked luggage and one cabin bag up to 12 kg. Two bags can be checked, subject to weight limits.
Cabin Baggage
All passengers may carry one cabin bag (55 x 35 x 25 cm) plus one small personal item such as a laptop bag or handbag. Weight limits are 7 kg for Economy and 12 kg for IndiGoStretch.
Infant Baggage
Infants under 2 years without their own seat are entitled to cabin baggage only. Strollers, carrycots, and car seats can be checked at no extra charge on IndiGo flights.
Special Equipment
Golf bags, skis, bicycles, and musical instruments require advance notice and are subject to additional fees. Items must be properly packed and within size limits.
Excess Baggage
Extra baggage can be purchased online or at the airport. Pre-booking online typically costs less than paying at check-in. Fees vary by route and weight.
Best Months to Visit
October to March typically offers the most pleasant weather in Kolkata and good value on flights. Monsoon season (June to September) sees lower fares but unpredictable weather.
Peak Travel Periods
Fares rise during Diwali (October/November), Christmas, New Year, and UK school holidays. Wedding season in India (November to February) also sees higher demand.
When to Book for Best Prices
Booking 6 to 10 weeks ahead usually provides the best balance of price and availability. IndiGo's UK routes are popular with the Indian diaspora, so seats fill quickly during peak periods.
Sales & Promotions
IndiGo runs periodic sales, typically during Indian festivals and at the start of each booking season. Crystal Travel can alert you to special fares when they become available.
