Flights from London to Portugal: the best tips from KAYAK users

Insights shared by verified travellers who flew the route from London to Portugal 
ZakFlew with TAP AIR PORTUGALLHR-LISMar 2025
Don't bother with business if you are flying out of LHR before 06:30 as the lounges and fast track security only open at 06:00 so you will not have time to use them. For short haul European flights this is most of the benefit of going business class. Hand luggage only is better with a large rucksack (30-40L) instead of a case with wheels is possible as gate agents will usually check cases with wheels on full flights and your rucksack is less likely to be gate checked.
ForrestFlew with TAP AIR PORTUGALLGW-OPODec 2024
Book a morning flight so if it's cancelled you have time to adjust. All the airlines operating between the two are budget airlines so don't expect great service.

Keep liquids altogether because you have to place it in a plastic bag from them
KFlew with TAP AIR PORTUGALLHR-LISApr 2024
Huge queues at Lisbon airport. Literally anywhere. Make sure you leave plenty of time for everything.

FAQs - booking Portugal flights

  • Can I fly directly from London to Portugal?

    You can fly directly from London Stansted Airport (STN) to Porto Airport (OPO) on Ryanair several times a day. Alternatively, there are non-stop flights from London Luton Airport (LTN) and Gatwick Airport (LGW) to Lisbon or Porto. From Heathrow Airport you can fly directly to Lisbon or Porto too.

  • Which Portuguese city should I choose to land in?

    The three major Portuguese Airports are rather neatly distributed. Faro Airport (FAO) is on the southern coast in the Algarve region, Porto Airport is in the north-west, while the capital of Lisbon is in the middle of the country on its west coast, served by Humberto Delgado Airport (LIS).

  • How should I choose my departure airport in London?

    Given that you can get direct flights from most London airports, your decision will come down to where in London you’re coming from. Heathrow is on the western outskirts, while Gatwick is a way south near Crawley. Stansted lies on London’s north-east outskirts near Bishop’s Stortford, and Luton Airport is to the north-west.

  • Can I save carbon emissions on flights from London to Portugal?

    Your best way of reducing carbon emissions when you fly to Portugal is to choose one of the direct morning flights from Heathrow to Lisbon. These flights emit just over half the carbon of the other flights flying this route. Later BA flights also offer significant reductions, albeit about 10% less than the morning flights.

  • Does Portugal have child seat laws?

    All children under the age of three must travel in a child seat in the back of the car, or in the front seat if you deactivate the airbags. Choose the back seat for more peace of mind. All children up to the age of 12 must also travel in child seats, in the front or the back.

  • Do I need a visa to enter Portugal?

    As Portugal is in the Schengen visa area, you won’t need a visa to enter the country and stay there for up to 90 days in any 180-day period. You can visit multiple times until you reach this limit. Just bear in mind that if you visit any other European countries in the Schengen area, these visits will also count towards your 90-day limit.

  • How does KAYAK find such low prices on flights from London to Portugal?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from London to Portugal.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from London to Portugal?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from London to Portugal is likely to change within 7 days, so travellers know whether to wait or book now.

  • What is the Hacker Fare option on flights from London to Portugal?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional return ticket. You could then fly from London to Portugal with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from London to Portugal?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from London to Portugal up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

  • What is the cheapest time of day to fly to Portugal?

    The cheapest time of day to fly to Portugal is generally at night, when retur flights cost £369 on average. Morning departures are around 11% more expensive than evening flights, on average. The most expensive time of day to fly to Portugal is generally in the morning, which is peak travel time and where the average cost of a ticket is £555.

Top tips for finding a cheap flight from London to Portugal

  • If you live in the Greater London area, your best bet is to fly from Heathrow Airport (LHR) ­– it’s only 15min from Paddington Station on the Heathrow Express train.
  • All London airports have dedicated, personalised limited mobility and hidden disability assistance services, from the parking lot to your seat on the aircraft, by prearrangement.
  • To explore the interior of Portugal, choose Lisbon as your arrival city. From here you can more easily reach inland cities like Evora and Santarem.
  • If you’re catching an onward flight to Portugal from Heathrow Airport, you can book a sleeping cabin to have a refreshing nap while waiting for your flight.
  • Car hire is easily available at all the major Portuguese international airports – you can book online in advance or hire one on arrival at one of the terminal kiosks.

A good, comfortable flight with friendly crew and good entertainment options.

Very rude person at the boarding desk; flight attendant coughing 3 inches from my face three times- not even covering her mouth; boarding process very unacceptable for older people with stairs to all planes (are you all stuck in the 1960’s?). I am sure that I am not remembering all of the negative things, but I am sure you get the message!

There was chaos at the Naples airport. We arrived three hours early for the flight but there was no invitation available about where to go to check bags until an hour later. Then we had to go to a different terminal to check our bags and check in and back to the first to board.

We flew TAP last October from Newark to Lisbon. The meal was bad. This flight had good food. Also, this flight was delayed. There were TAP employees waiting at Lisbon to make sure we made our connecting flight. I find the TAP website and app frustrating, but the service once we reached the airport was very good

The airport temperature at the airport and on the flight was too warm

Boarding too way too long. Biggest peeve: zero in-seat power in economy! No plug sockets, no USB ports. Plane was an A330, so not old.

boarding is so disorganized, i was literally appalled at the boarding experience

Comfortable but not Polaris or Delta comfort Business Class. Overall 7 out of 10

Tap air Portugal was the best I will traveling again with u guys. Thank u.

The long wait at JFK made the trip horrible. Also not having enough buses when we deplaned was annoying

I got caught using a stolen credit card number. Michelle Siziba is my name Nice to London Gatwick on 7/31/25.

Not happy with price of luggage or that we had no choice but to pay whether cabin or hold. I didn't book seats but this is unnecessary extra money along with suitcase

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

sadly in Basel & Naples- no jetway we had to climb up and down stairs with our max size carry-on luggage, which was not fun!!!

This was our first time using them. I gave okay ratings for food and entertainment because it was minimal or not provided so I couldn't judge, but much better than most budget carriers we have ever used.

We were charged a ridiculous amount for a name spelling error on ticket which I would’ve corrected if I received pre-check info more than 1/2hr before flight. Then we were told at ticket counter that our bags were fine for boarding but then we’re charged another ridiculous amount to take in our luggage despite being told differently. Flight itself was great. Charges were unfair.

Apart from an email about re configuring passenger seating less than 24hrs before flying it was all good.

There were a lot (4 I think) of EasyJet flights leaving Agadir, we arrived two and a half ours before our flight. Very slow to get through the booking in, passport control and security!! We had booked in on line but had to Queue with others who had not to drop our bags off!,

We boarded and then sat on the tarmac for an hour….probably not E Jets fault. But the gentleman that checked us in and took our luggage was exceptionally friendly and calming for early morning/ confused passengers. As always, it’s the people that make or break an experience, right?

I was hesitant to book with a low cost airline due to previous experience but Easy Jet surpassed my expectations. I would definitely book a flight with them again! Seemless booking, upfront about baggage fees, professional, and helpful staff.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

Straight forward checking as long as you have completed every single detail online, prior to checking day. Efficient boarding, seating is ok for a two hour flight. Fulfilledour travel requirements from Manchester to Marseille.

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

I checked in to bags, one arrived one was delayed. I did not receive the bag for 4 days - arrived on Tuesday, received bag on Saturday!

It was ok. Our flight was delayed 2 hours, and then again on arrival. The explanation given felt feeble.

The booking agent, cheapflightsfares, messed up, and the information for the seats we paid extra for was not sent to American Airlines. We were separated on the return flight and sent to the lowest economy section. The flight attendant helped arrange seating at the back of the plane to allow my wife and me to sit together.

The staff were fantastic and couldn't have been more accomodating; however, the air-conditioning was broken in our section of the aircraft, leaving us feeling extremely cold and unwell on arrival in Johannesbury. The head sets were also faulty, causing difficulty when listening to announcements and entertainment.

I liked the comfort of the seats, very attentive crew, and the meals were excellent.

We spent twice as long on the runway waiting to take off as we did in the air.

We were kicked off this flight by British Airways due to delays on our connecting flight also operated by British airways and were rebooked on a different carrier which delayed our arrival home by > 26 hours.

Everything about the flight check-in was smooth no line the plane is clean and bathroom

Excellent everywhere but Philly, the most rotten airport in the world.

Great crew. Seats do not recline :( but it is budget so i should have known. Otherwise comfy leather chair. Slight slim chair but again budget so expected. No entertainment do makes journey boring. Recommend packing plenty of snacks and games or download plenty of films and music in your device. Staff excellent. Clean flight. On time.

Both of my flights had issues with their time slot with air traffic control, so they left over an hour late and the flight back to London was delayed by over an hour. Please provide more clarity about baggage requirements on booking sites, your website and within the app. I had to pay for extra bags at the airport when departing London, because they didn’t specify that your carry on bag can only be a backpack and not a trolley, my trolley bag fit the size requirements of the backpack but still I was made to pay

The crew at Check-in was very helpful. It’s was appreciate.

It’s a budget airline. You get what you pay for. They insisted on getting us out of the gate and into our slot on time. They got us to the destination safely. Aircraft was clean and well maintained. What more could we want

Half an hour delay. Squeezed into a small Departure Lounge with very few seats. Noisy flight with screaming unruly kids. Loud IPads and Phones. Heaven!

Were delayed in the airport for 5 hours with no explanation. Flight kept getting delayed by an hour at a time and wizz air staff were no where to be found

The flight was delayed 5 hours and I'm and invalid,I wan a refund for this

The cabin crew on that flight were super fantastic and super helpful. They were so polite and considerate that i felt i travelled with a 5star airline.

Delayed delayed delayed - always with Wizzair. Staff were friendly and well mannered but clearly the company is unorganized and the aircrafts are outdated.

It's a budget airline. Great for short flight. Smooth landing.
