English school summer holidays usually end in late August or the first days of September, so Heathrow (LHR) moves out of peak family demand while southern Europe is still a reasonable weather bet. The wider London ecosystem - Gatwick (LGW), Stansted (STN), and Luton (LTN) - still holds most of the budget inventory, but Heathrow keeps competitive fares on some European corridors once August pricing eases. 25+ destinations across 9 countries are currently available from Heathrow at the fares below.

This report tracks the 25 lowest observed fares from LHR this month, sourced daily from Travelpayouts and ranked by price. The current cheapest fare is €33 to Barcelona (direct). Average across the top 25: €57.

Key observations

Cheapest market this month: Barcelona (Spain) at €33 - direct.
Direct flight coverage: 14 of the top 25routes are non-stop. Heathrow's scale still supports direct connections that require a hub transfer from most other European airports - useful in September when short-haul prices are usually kinder than in August.
Geographic spread: The top 25 routes reach 9 countries. Spain, Greece, Italy, and Portugal typically still dominate the cheapest corridor from LHR in September, with less family-holiday pressure than August and sea temperatures that remain usable in the south.
London airport strategy: These fares are from Heathrow (LHR). For lower prices on the same European routes, check Stansted (STN) and Luton (LTN), served mainly by Ryanair and easyJet, often well below Heathrow on overlapping destinations. Average shown here: €57.
Booking tip: September is a better month than August to fly from London if the destination is still warm. Mid-week departures (Tue-Wed) and weekday returns usually undercut the Friday/Sunday pattern. If October or November travel is possible, lock those dates now rather than waiting for another drop. All prices are per-person one-way fares.
