Cheap Flights Lisbon to London: Six Airports, One Cheap Seat

Check live Lisbon–London fares on TopTravelCentre →

Cheap flights from Lisbon to London are a buyer’s market: five airlines, six airports and dozens of daily departures mean round trips regularly start from €50–90 if you book a few weeks out. The trick isn’t finding a flight — it’s finding the right one. Search and book your flight on TopTravelCentre and compare airports as carefully as fares; landing at Gatwick instead of Stansted can save you an hour and £20 in transport.

How to find cheap flights from Lisbon to London

  1. Book 3–6 weeks ahead. Short-haul European routes price best in that window; earlier rarely helps, later always hurts.
  2. Match the airport to your plans, then price the rest. Landing at London City for a Canary Wharf meeting or Luton for a budget weekend are very different trips. Filter by airport first, fare second.
  3. Travel light if you can. On this corridor the low-cost base fare assumes a cabin bag at most; a checked suitcase can double the ticket price. Pack for carry-on and the maths work in your favour.

Flight time and airports

The nonstop covers about 1,600 km in 2 hours 30 minutes to 2 hours 45 minutes, and there are many every day.

Lisbon Humberto Delgado (LIS) is compact and metro-connected — you can be checking in 20 minutes after leaving Baixa. On the London side you have real choice:

  • Heathrow (LHR): best for west London and connections; Elizabeth Line to central London in ~45 minutes.
  • Gatwick (LGW): south of the city; Gatwick Express to Victoria in about 30 minutes.
  • Stansted (STN): farther out; Stansted Express to Liverpool Street in ~50 minutes. Often the cheapest seats.
  • Luton (LTN): north; train plus shuttle to St Pancras in about an hour. Cheapest of all, least convenient.
  • London City (LCY): closest to the centre; business-oriented flights, fewer bargains.

Best time to fly and cheapest months

  • January–February: the annual floor. Grey London, green prices — round trips near €50 happen.
  • March–April: fares rise toward Easter, one of the year’s most expensive windows on this route.
  • May–June: long days, moderate prices if you dodge UK school-holiday weeks.
  • July–August: peak; still well-served, but book 6+ weeks out.
  • September–October: post-summer softness; excellent value with decent weather.
  • November: cheap, quiet, and the Christmas lights go up late-month.
  • December: low until mid-month, then the holiday surge.

Cheapest months are typically January and February.

Five money-saving tips for this route

  1. Price the train to the airport, not just the flight. A €25 saving flying into Luton evaporates against a £25+ transfer if you’re staying in central London.
  2. Mix airlines. Ryanair out, TAP back is a classic play here — both directions are cheap, and mixing widens your time options.
  3. Fly Tuesday–Thursday. Weekend-bound leisure traffic makes Friday and Sunday the priciest days.
  4. Set alerts across all six airports. The market moves airport by airport; alert on the city, not the field.
  5. Check in online. On low-cost carriers the airport check-in fee is pure penalty — 30 seconds in the app saves €20–55.
