How to Find Cheap Flights to Delhi from the UK: Insider Tips and Best Booking Times

Travelling to India’s vibrant capital doesn’t have to cost a fortune. Finding cheap flights to Delhi from the UK is all about timing, planning, and using the right tools. Booking tickets around 2-3 months in advance often yields the best fares. Avoid peak travel seasons like Christmas, Easter, and summer holidays, as prices tend to skyrocket during these times.
Flexibility is key. Flying midweek, especially on Tuesdays or Wednesdays, can significantly lower costs. Consider departing from alternative airports such as Birmingham or Manchester instead of London, which often have less expensive options. Setting up fare alerts on comparison sites like Skyscanner or Google Flights helps track price drops efficiently. Another useful strategy is to browse flights in incognito mode to avoid dynamic pricing, which can raise fares based on repeated searches. Sometimes, booking two one-way tickets with different airlines works out cheaper than a return fare. Choosing flights to Delhi during the off-season, particularly between mid-January and March or late September to early November, can also bring better deals and a more comfortable travel experience. Staying patient, flexible, and well-informed can lead to impressive savings on your next journey to this culturally rich destination.

1. Best Time of Year to Book Flights to Delhi
When planning a trip to Delhi, timing is everything, especially if you're looking to save on airfare. Understanding the seasonal trends can make a significant difference to your travel budget. Flights to Delhi are typically at their most expensive during peak travel periods such as December, especially around Christmas and New Year, and during major Indian festivals like Diwali (usually October or November) and Holi (March). These periods see a surge in demand, which inevitably drives up prices. The cheapest months to fly are generally mid-January to early March and late September to early November. These fall within the shoulder seasons, times when travel demand dips after the peak periods. During these months, airlines often lower their fares to attract passengers, making it an ideal window for budget-conscious travellers. The weather is also relatively pleasant during these times, especially in February and October, offering a comfortable experience without the extreme summer heat or winter fog. If flexibility allows, consider avoiding summer altogether. The months of May and June bring scorching temperatures to Delhi and are also popular for school holidays, leading to higher prices and busier flights. Booking around 8–12 weeks in advance is typically recommended for the best deals. Mid-week flights, particularly on Tuesdays and Wednesdays, often come with reduced fares compared to weekend travel. Also, staying flexible with your travel dates and being open to flying into or out of alternative UK airports can reveal even better deals. In short, targeting off-peak travel periods and shoulder seasons not only helps secure cheaper flights to Delhi but also ensures a more relaxed and enjoyable journey overall. A little planning ahead can go a long way in saving money and avoiding the stress of last-minute, high-priced bookings.

2. How Far in Advance Should You Book?
Securing cheap flights to Delhi from the UK often depends not just on when you travel, but when you book. Timing your ticket purchase well in advance can lead to significant savings. For international routes like the UK to India, the ideal booking window is typically between 8 to 12 weeks before departure. During this period, airlines tend to offer competitive prices before demand starts to build. That said, the best timing can vary depending on the season. If you’re planning to fly during peak travel times such as Christmas, New Year, or during Indian festivals like Diwali and Holi, it’s wise to book even earlier, around 4 to 6 months in advance. Seats fill quickly during these high-demand periods, and prices climb sharply the closer you get to the travel date. For off-peak or shoulder seasons, like mid-January to March or late September to early November, booking 6 to 10 weeks ahead often brings the best value. Airlines may reduce prices to encourage bookings during these quieter months, giving you more flexibility without the need to book far in advance. It’s also helpful to set up fare alerts using tools like Google Flights, Skyscanner, TravelUp, or Hopper. These will notify you when prices drop for your preferred route, allowing you to act at the right moment. Being flexible with your travel dates and avoiding weekends can further help you secure lower fares. Avoid leaving things to the last minute. While some believe that last-minute deals are common, they’re rare for long-haul routes like flights to Delhi, where demand stays relatively high. Booking in advance not only saves money but also ensures better flight times and seating options for a more comfortable journey.

3. Choosing the Right Departure Airport in the UK
When booking flights to Delhi, the departure airport can play a crucial role in how much you pay. While London Heathrow is the busiest and most connected UK airport, it’s not always the most affordable. Exploring alternative airports like Manchester, Birmingham, or Glasgow can uncover better fares and a smoother travel experience. London Heathrow offers the widest range of direct flights to Delhi, operated by major airlines such as British Airways, Virgin Atlantic, Air India, and Vistara. Its frequency and competition can sometimes result in decent deals, especially if booked early. However, Heathrow’s popularity also means prices can be higher during peak times, and the airport experience itself may be busier and more time-consuming. Manchester Airport is a strong alternative for travellers in the North of England. It offers both direct and one-stop flights to Delhi, with carriers like Emirates, Lufthansa, and Qatar Airways providing good connections. Prices here can often be more competitive than Heathrow, particularly for indirect routes with short layovers. Birmingham Airport serves as a convenient option for those in the Midlands. While direct flights are less frequent, several one-stop services via the Middle East offer attractive prices. It’s generally less crowded, making for a quicker and less stressful check-in and boarding process. Glasgow Airport, though offering fewer choices, occasionally provides cheaper fares, especially through one-stop routes with airlines like KLM or Turkish Airlines. For Scottish travellers, flying from Glasgow can eliminate the need for domestic transfers or lengthy journeys to English airports. In summary, while Heathrow remains the most convenient for direct options, comparing fares from regional airports like Manchester, Birmingham, and Glasgow can reveal surprising savings. A bit of flexibility on where you depart from could shave a significant amount off your overall travel costs.

4.  Weekday vs Weekend Flights: When is it Cheaper?
When booking flights to Delhi from the UK, the day of the week you choose to travel can have a noticeable impact on the price. Generally, weekday flights—especially on Tuesdays and Wednesdays—tend to be cheaper than weekend departures. This is because midweek travel is less popular with both leisure and business travellers, leading airlines to offer lower fares to fill seats. In contrast, weekends—particularly Fridays and Sundays—are typically in high demand. Friday departures are popular with holidaymakers and business travellers looking to make the most of their weekend, while Sunday returns are ideal for those aiming to get back in time for the working week. As a result, airlines often increase fares on these peak days. Booking tools like Google Flights or Skyscanner often show clear price differences when you compare the same route across various days. For instance, a flight departing on a Wednesday could be £50–£100 cheaper than the same journey on a Friday. Over long-haul distances such as the UK to Delhi, these savings add up quickly. If you have flexibility in your schedule, departing midweek and returning midweek is usually the most economical option. Even adjusting your travel dates by just one or two days can unlock much better fares. It’s also worth noting that very early morning or late-night flights during the week may be less desirable for some travellers, which often translates into slightly lower prices. In summary, travelling on weekdays—particularly Tuesdays and Wednesdays—can lead to significant savings compared to weekend flights. If cost is a key factor in your planning, staying flexible and opting for midweek departures and returns is a simple yet effective way to reduce the overall expense of your trip.

5. Use of Flight Comparison Tools and Fare Alerts
Finding cheap flights to Delhi can be much easier when you make use of flight comparison tools and fare alert systems. These platforms allow you to compare prices across multiple airlines and booking websites, helping you to identify the best possible deals without hours of manual searching. Skyscanner is one of the most popular and user-friendly comparison tools. It allows you to view flight prices across an entire month, helping you pinpoint the cheapest days to fly. Skyscanner also enables you to set up fare alerts, notifying you by email or app whenever prices drop for your selected route. This feature is ideal if you’re planning and want to monitor fares over time. Google Flights is another powerful tool. It offers a clean interface, real-time price tracking, and predictive insights, showing you whether fares are likely to rise, or fall based on historical trends. The calendar view highlights the cheapest travel dates briefly, making it easy to choose the most cost-effective option. Kayak works in a similar way and includes flexible search features like exploring nearby airports and mix-and-match return flights with different airlines. It also offers “Price Forecast” predictions, which advise whether you should book now or wait. Using these tools in combination can offer a well-rounded perspective of the market. Enable fare alerts for all three platforms to maximise your chances of spotting a bargain. Don’t forget to use incognito mode when browsing, to avoid cookies influencing price changes based on your search history. In short, flight comparison websites and fare alerts are essential tools for budget-conscious travellers. They simplify the process, offer real-time insights, and provide a smart, hands-off approach to finding the best deals on flights to Delhi.

6. Alternative Airlines and Routes to Consider
When searching for cheap flights to Delhi from the UK, it’s easy to focus solely on major carriers offering direct routes. However, exploring less obvious airlines and routes with stopovers can often lead to better deals and even more comfortable travel experiences. While direct flights with airlines like British Airways, Virgin Atlantic, and Air India offer speed and convenience, they tend to come with higher price tags—especially during peak travel seasons. If you’re willing to consider one-stop routes, you can often find more competitive fares without adding excessive travel time.
Middle Eastern carriers such as Qatar Airways, Emirates, and Etihad Airways frequently offer excellent service, modern aircraft, and competitive pricing, with brief stopovers in Doha, Dubai, or Abu Dhabi. These airlines often run promotions and are known for their generous baggage allowances and high in-flight standards. Other budget-friendly options include Turkish Airlines via Istanbul or KLM via Amsterdam. These airlines provide smooth transit and allow you to avoid the crowds and costs of London’s major airports if flying from regional hubs like Manchester, Birmingham, or Glasgow. Asian carriers like SriLankan Airlines or Thai Airways occasionally offer attractive fares to Delhi with longer layovers, which can even give you the chance to explore a second destination. While slightly longer in duration, these alternative routes can lead to savings of £100 or more, especially if booked in advance. They also tend to have greater availability during busy periods, offering more flexibility in travel dates. In summary, being open to flying with alternative airlines and including a stopover can unlock significant savings. The slight inconvenience of a layover is often outweighed by the reduced fare and added comfort offered by these quality carriers.

7. How to Use Points, Miles, and Credit Card Offers
Using points, miles, and credit card rewards is a smart way to reduce the cost of flights to Delhi, often turning a high-priced ticket into a more affordable or even free journey. Many airlines and banks offer loyalty schemes that reward you with miles for every pound spent on flights, purchases, or through partner programmes.
Airline loyalty programmes such as British Airways’ Executive Club or Virgin Atlantic’s Flying Club allow you to accumulate points (Avios or Virgin Points) when flying, shopping with partners, or using affiliated credit cards. These points can then be redeemed for flights, upgrades, or airport lounge access. Signing up is free, and accumulating points can quickly add up, especially if you travel frequently or use co-branded credit cards.
Using airline credit cards is one of the fastest ways to earn miles. Cards such as the British Airways American Express or Virgin Atlantic Mastercard often come with generous welcome bonuses when you meet a minimum spend within the first few months. These bonuses alone can sometimes cover a one-way or even return flight to Delhi.
Flexible reward schemes like American Express Membership Rewards or Chase’s reward programmes (if you hold a relevant card) allow you to transfer points to various airline partners, giving you more options for booking.
Keep an eye out for promotions and bonus point offers, and consider booking flights during reward sales, where fewer points are needed for redemption. Combining miles with cash, known as “part pay with points”, is another useful option if you don’t have enough to cover the entire fare. In short, by strategically using points, miles, and credit card perks, you can significantly cut the cost of your flights to Delhi, making premium travel more accessible and affordable.

8. Seasonal Events in Delhi that Affect Flight Prices
Delhi is a vibrant city with a rich cultural calendar, and its seasonal events have a direct impact on flight prices. Travellers planning a visit must be mindful of local festivals and public holidays, as these periods typically lead to a surge in airfare due to high demand. One of the most significant events is Diwali, the Hindu festival of lights, usually celebrated in October or November. It’s one of the busiest travel periods in India, with locals flying home to be with family and tourists arriving to witness the festivities. Flights to Delhi during the Diwali season often become significantly more expensive, especially if booked at short notice. Holi, the festival of colours, usually falls in March. Though slightly less expensive than Diwali in terms of airfare, it still sees a spike in prices as both domestic and international travellers flock to the city to take part in the celebrations. Other important times include Christmas and New Year, when many people travel for holiday breaks. Additionally, Independence Day (15 August) and Republic Day (26 January) also bring increased air travel within India, sometimes affecting prices for international flights into Delhi. The wedding season, typically from November to February, also leads to high travel volumes, especially with overseas family members flying in. Though not a fixed period, it often overlaps with holiday peaks and drives up prices. To avoid inflated fares, it’s wise to either book well in advance for travel during these events or plan your trip during off-peak months, such as mid-January to early March or late September. In summary, understanding Delhi’s festive calendar can help you avoid periods of high airfare demand, enabling you to plan smarter and save more on your journey.
