Cheap flights from London to Porto

November is the cheapest month on this route, and the price calendar shows fares for every month from September through to August, so you can see how the year moves before you commit. Summer and the school holidays push fares up, and December around Christmas is busy in both cities. Spring and autumn are the sweet spot: milder weather in Porto, smaller crowds, and more room to choose your departure day. Midweek flights tend to be calmer than weekend ones, and booking a few weeks ahead usually beats leaving it late.

Most of the capacity on this route belongs to low-cost carriers. Ryanair, Easyjet and its EasyJet Europe arm, Wizz Air UK and Wizz Air Malta sell point-to-point tickets, so the fare buys your seat and the cabin bag rules depend on the fare you pick. Vueling Airlines and Malta Airlines appear on some departures, TAP Portugal is the full-service Portuguese option, and Portug and Mokulele Flight Service also turn up in the results. Direct flights are available; a connection usually costs you time rather than money. Compare what is included, not just the headline fare.

You land at Porto airport, the city's only airport, and it sits a short ride from the centre rather than far out of town. The metro and local buses connect the terminal with the centre, and taxis and pre-booked transfers wait outside arrivals. Allow time at the London end too: Heathrow, Gatwick, Stansted, Luton and London City feed different rail and road links, so check which one your ticket names before you plan the journey to it.

Country facts: Wikidata

• Check which London airport your ticket names, because Heathrow, Gatwick, Stansted, Luton and London City are not interchangeable.
• Read the baggage rules on your fare before you book, since low-cost tickets often charge for a checked bag.
• If you book a connection, make sure both legs sit on one ticket so a delay does not leave you stranded.
• Carry a valid passport or identity card for Portugal and check the entry rules that apply to you.
• Book early for summer and the Christmas period, and look at November if you want the lowest fares.
• Compare the total cost, not the headline fare, once bags and seats are added.
