Cheap flights from London to Barcelona

October is the cheapest month on this route, with September and November close behind. Summer is the busy stretch: July and August fill up with holiday traffic and fares climb, while late spring and early autumn stay mild and quieter. Winter is calm apart from the Christmas and New Year weeks, when prices jump again. Midweek departures on Tuesday and Wednesday usually cost less than Friday and Sunday, and early-morning or late-night slots often come in lower than midday ones. Book summer trips well ahead; in the quieter months you can often wait and watch the calendar.

Several carriers fly between London and Barcelona. Ryanair, Ryanair UK, easyJet, EasyJet Europe, Wizz Air UK, Wizz Air Malta, Jet2 and Vueling Airlines are the low-cost names you will see most often, and they price the seat on its own, with bags and seat choice added as you book. Norwegian International and Mokulele Flight Service also turn up in results, but not every carrier here sells a simple non-stop hop, so check whether a fare is direct or routes you through a hub. Full-service tickets bundle more into the fare, which is why two tickets that look alike can end up far apart once baggage is counted.

Your flight lands at Josep Tarradellas Barcelona airport, the city's main gateway and the one serving this route. It sits outside the city, a short ride from the centre rather than a walk away, so sort out the last leg before you land. Trains, shuttle buses and taxis all connect the airport with the centre, and the train is the usual pick if you are travelling light. Taxis are quicker, but the queue stretches when several flights land together, and the train stops running late at night, so check the timetable against your arrival time. Confirm which terminal your return flight leaves from before you head back.

Country facts: Wikidata

• Check which London airport your fare leaves from, since Heathrow, Gatwick, Luton, Stansted and London City all serve this route.
• Confirm the flight is direct and not a connection through a hub, as some carriers here sell both.
• Add baggage to the fare before you compare, because on low-cost tickets a cabin bag and a checked bag change the total.
• If you book two separate tickets, leave a long gap between them, since a missed connection is yours to fix.
• Carry a valid passport or national identity card for Spain and check the entry rules that apply to you.
• Watch the price calendar and aim for October if your dates are flexible.
