How to Find the Cheapest Flights
Finding cheap flights doesn't have to be complicated. With TravelDealForge, you can compare prices from over 100 airlines and booking sites in seconds. Our powerful search engine finds the best deals, error fares, and hidden discounts that can save you hundreds on your next trip.
Why Flight Prices Vary So Much
Airline pricing is dynamic, changing constantly based on demand, competition, fuel costs, and dozens of other factors. A flight that costs £300 today might be £150 tomorrow—or £500. That's why comparing prices and being flexible with your travel dates is crucial for finding the cheapest flights.
Airlines use sophisticated algorithms to maximise revenue. They know when business travelers typically book (last minute) and when leisure travelers search (weeks ahead), adjusting prices accordingly. By understanding these patterns, you can often beat the system.
Best Strategies for Cheap Flights
1. Be Flexible with Dates: Flying midweek (Tuesday-Wednesday) is typically 20-30% cheaper than weekends. Our flexible date search shows you the cheapest days to fly.
2. Book at the Right Time: For domestic flights, 1-3 months ahead offers the best prices. International flights are often cheapest 2-8 months before departure.
3. Consider Nearby Airports: Flying into a secondary airport can save significant money. London Stansted vs Heathrow, or Newark vs JFK, can mean hundreds in savings.
4. Set Price Alerts: Don't obsessively check prices. Set up alerts and we'll notify you when fares drop to your target price.
5. Use Incognito Mode: Some airlines track your searches and may raise prices. Search in private/incognito mode for unbiased results.
Budget Airlines vs Full-Service Carriers
Budget airlines like Ryanair, EasyJet, and Wizz Air can offer incredible savings—sometimes 80% less than traditional carriers. However, the base fare is just the starting point. Factor in baggage fees (£25-50 per bag), seat selection (£5-30), priority boarding, and even card payment fees.
For short European hops with just a personal item, budget airlines are unbeatable. For longer journeys or when you need checked luggage, calculate the total cost including extras before deciding.
Finding Error Fares and Mistake Prices
Error fares occur when airlines accidentally price flights far below normal rates—sometimes 90% off. These mistakes happen due to currency conversion errors, technical glitches, or human data entry mistakes. While airlines can cancel these bookings, many honor them.
Subscribe to our deal alerts to catch error fares the moment they appear. These deals typically last only a few hours before being corrected.
Frequently Asked Questions
How do I find the cheapest flights?
Use our flight comparison tool to search multiple airlines at once. Be flexible with your dates, consider nearby airports, and book 6-8 weeks in advance for the best prices. Setting up price alerts helps you catch sales and price drops.
What is the cheapest day to fly?
Tuesdays and Wednesdays are typically the cheapest days to fly, followed by Saturdays. Avoid Fridays and Sundays when business travelers and weekend trips drive up prices.
When should I book flights for the best price?
For domestic flights, book 1-3 months in advance. For international flights, book 2-8 months ahead. Last-minute deals exist but are unpredictable. Peak seasons (summer, holidays) require earlier booking.
Are budget airlines worth it?
Budget airlines can save you 30-60% on airfare, but factor in extras like baggage fees, seat selection, and meals. For short trips with just carry-on luggage, budget airlines offer excellent value.
How can I find error fares and mistake prices?
Subscribe to our deal alerts and check our deals page regularly. Error fares are often available for just a few hours, so quick booking is essential. Follow us for instant notifications of pricing mistakes.
Do flight prices go down on certain days?
Airlines often release sales on Tuesdays, with competitors matching prices by Wednesday. However, prices fluctuate constantly based on demand, so monitoring prices over time is more effective than waiting for specific days.
Is it cheaper to fly from different UK airports?
Often yes! Flights from Manchester, Birmingham, or Edinburgh can be 20-40% cheaper than Heathrow for the same destination. Factor in travel costs to the airport, but regional airports often have better deals, especially with budget carriers.
Do connecting flights save money over direct?
Connecting flights can save 10-30% on popular routes, especially long-haul. Consider layovers of 2-4 hours for comfort. Self-connecting (booking separate flights) offers more savings but carries more risk if delays occur.
