London to Barcelona: 1,138 km, 2h 05m–2h 15m flight time. 5 airlines including Vueling and easyJet. Best months: March, April, May. From £55–120.
London to Barcelona is one of the busiest short-haul routes in Europe, operated by multiple airlines from several London airports. The abundance of competition — particularly between easyJet, Vueling, and Ryanair — keeps prices low year-round, with fares under £50 one-way available on flexible dates outside of peak season. Heathrow offers the fastest connection via British Airways or Iberia for business travelers, while Gatwick, Stansted, and Luton serve budget options.
Barcelona is a year-round destination, but spring (April–May) and autumn (September–October) offer the best combination of pleasant weather, manageable tourist numbers, and affordable flights. Summer is peak season — the beaches, architecture, and food scene are all at their most vibrant, but hotel prices and flight costs spike sharply. From Barcelona El Prat, the city center is 40 minutes by Aerobus or 30 minutes by metro L9.

London Gatwick (LGW) has the most Barcelona departures overall, with easyJet and Vueling both operating frequently. Heathrow (LHR) is best for premium travelers via British Airways. Stansted is cheapest via Ryanair but involves a longer transfer into London.
For summer travel, book 2–3 months ahead for reasonable prices. For shoulder season, 4–6 weeks is usually fine. Fares become expensive within 2–3 weeks of departure unless there is excess capacity.
A Eurostar to Paris plus a TGV to Barcelona takes about 9–10 hours total and can be cost-competitive in shoulder season. It also involves no airport check-in stress and delivers you to the heart of Barcelona at Sants station.
