Cheap flights from Lisbon to London

The weeks around December often price lower than the Christmas and New Year stretch, and December itself is the cheapest month in the calendar on this route. Compare dates just before and after the holiday peak, then use the full price calendar for August school holidays and other busy London and Lisbon periods. Weekday departures can help, but the month matters more than the day, and flexible dates are worth more than one fixed plan. Check neighbouring days before you commit, because a date either side of a busy week can change the fare more than the airline does.

Most names on this route are low-cost carriers, while TAP Portugal and Air Europa sit on the full-service side, and Portug is a name that does not tell you enough on its own, so check its fare rules before judging it. Ryanair, Easyjet, EasyJet Europe, Volotea, Wizz Air Malta and Norwegian International usually sell a basic fare with extras priced separately, which means bags, seats and boarding choices can change the total. Vueling Airlines belongs with the low-cost group by name, but its rules still need reading like the rest. Direct flights exist, yet any itinerary stitched from separate tickets leaves the connection risk with you, so read the inclusions before you compare headline prices.

You may land at London City, Gatwick, Heathrow, Luton or Stansted, and each airport sits in a different direction from central London, from the eastern docks to the western, southern and northern outskirts. London City and Heathrow tend to mean less travel into town, while Gatwick, Stansted and Luton usually need a longer rail or coach ride. Check the airport code and your late-night transport plan before booking, because a low fare into a distant airport can cost time on arrival. If the last direct service has gone, price the onward transfer before you commit.
