Most trains will take less than an hour, even to the far-flung London airports, while cars may take a bit longer if you run into traffic. Although there are plans for a second airport in Lisbon, your only choice is to land at Portela Airport – but the benefit of this is that it’s much closer to the centre of Lisbon than London airports are downtown London.

Heathrow is also connected to the centre of London using the Piccadilly Line on the London Underground and via the Heathrow Express, which takes you straight from the city to the airport. Gatwick offers road and rail connections, with the M23 motorway that connects to the M25 London Orbital. The airport’s train station seamlessly connects to downtown London. Stansted offers connections to London via the M11 motorway and via rail, with the airport train station. It also has bus connections to London central. Likewise, Luton is just off the M1 motorway and offers rail and bus connections back to the city. Lisbon’s Portela airport is connected to the city via the Red Line of the Lisbon Metro, but it also has bus and train connections and an Aerobus for passengers with a lot of large luggage.

From the airport, you will need to catch the metro or the Aerobus with a stop, and a transfer at the Cais de Sodre train station and the entire journey will take no more than 1h 30min.
