Budget airlines have transformed UK air travel, making weekend trips to European cities incredibly affordable. EasyJet and Ryanair dominate short-haul routes, while Jet2 specializes in holiday destinations around the Mediterranean. For long-haul connections, Heathrow remains the primary hub with flights to virtually every continent.

The UK offers an extraordinary density of experiences within a compact geography: London's world-class museums and theatre, Scotland's dramatic highlands, Wales's castles and coastline, and Northern Ireland's rugged beauty. With six major airports serving London alone and dozens of regional airports, the UK is one of Europe's most accessible destinations by air. Budget airlines have made domestic UK flights and European connections remarkably affordable.

Compare all 6 London airports for every booking as fare differences can reach 50 to 100 GBP.
London has Heathrow, Gatwick, Stansted, Luton, City, and Southend airports, each serving different airlines and markets. Stansted and Luton offer the cheapest Ryanair and Wizz Air fares, while Gatwick is easyJet's main hub. A flight from New York to Stansted via Norwegian can cost 100 to 200 USD less than the same dates to Heathrow on British Airways, even after factoring in the longer train transfer to central London.
Fly from Manchester or Edinburgh instead of London for northern European and Scandinavian routes.
Manchester and Edinburgh often have lower fares than London for routes to Scandinavia, Iceland, and northern Europe, plus shorter security queues and less airport stress. EasyJet and Ryanair operate extensive networks from both airports. A Manchester-to-Copenhagen return can cost 30 to 50 GBP less than the London equivalent, and both airports are faster to process than the chronically congested London terminals.
Book European short-haul flights 6 to 8 weeks ahead for the optimal price-to-availability balance.
Data from Google Flights and Skyscanner shows that 6 to 8 weeks before departure is the sweet spot for UK to Europe budget carrier fares. Booking earlier gives limited additional savings, while waiting until 2 weeks before departure can increase prices by 50 to 200 percent on popular routes. Set fare alerts for your preferred dates and book when the price drops to or below the route's historical average.
Stansted and Luton typically offer the cheapest fares as they're primarily served by budget airlines like Ryanair and Wizz Air. However, Gatwick's easyJet hub often has competitive prices too.
Manchester often has lower fares for northern European and Mediterranean destinations, plus it avoids London's higher airport taxes. Compare both before booking.
UK citizens can visit EU/Schengen countries visa-free for up to 90 days in any 180-day period. You'll need a passport valid for at least 3 months beyond your stay.
For the best fares to United Kingdom, book 6-8 weeks in advance for short-haul European flights and 2-3 months ahead for long-haul routes. Tuesdays and Wednesdays typically offer lower fares. Shoulder season (spring and autumn) provides the best balance of price and weather.
United Kingdom is served by both major international airports and smaller regional ones. Budget airlines often fly into secondary airports that may be further from city centers but offer significantly cheaper fares. Factor in transfer costs when comparing airports — a cheaper flight to a distant airport may not save money overall.
Baggage policies vary significantly between airlines. Full-service carriers typically include 23kg checked luggage, while budget airlines charge extra. Carry-on limits usually range from 7-10kg. Always check your specific airline's policy before packing to avoid expensive airport surcharges.
Major European hubs like London, Frankfurt, Paris, and Amsterdam typically offer the most direct connections to United Kingdom. From North America, direct flights are available from New York, and sometimes from other major cities depending on the season. Connecting flights through European hubs often provide more schedule flexibility.
