Cheap flights under €50 from London

Sub-€50 fares from London are most commonly associated with low-cost carriers and short routes with strong competition. Airlines like Ryanair, Wizz Air, and easyJet use dynamic yield pricing - seats open cheap when a flight is first loaded and adjust upward as the cabin fills. The fares listed here were recently found through the Travelpayouts data network; availability and final prices should always be confirmed on the booking provider's website before completing a purchase.

The €50 ceiling covers the base fare only. Budget carriers charge separately for cabin bags, checked luggage, and seat selection. Before booking a sub-€50 flight, check the airline's luggage policy for your specific route and booking date - fees for a standard cabin bag vary by airline and can materially increase the return-trip price. Always compare the full checkout total, not just the headline fare.

Lower fares are often easier to find several weeks in advance, while peak-summer and holiday travel usually benefits from booking earlier. Last-minute sub-€50 fares do appear when airlines need to fill seats, but they are too unpredictable to rely on when your dates are fixed.
