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.

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 £274 on average. Morning departures are around 9% 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 £417.

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.

Boarding process was fast and efficient. Short flight but on time and well organized. I would certainly fly TAP again.

Boarding process was fast and efficient. Short flight but on time and well organized. I would certainly fly TAP again.

Very borderline, low budget airline without low budget prices There are no counts of soda, everything is dispensed enlarged bottles and poured into tiny cups about 70 mL so in order to keep hydrated you have to take 3-4 cups at a time. Also, there was only one food item offered, pasta, they ran out of chicken right away. Snack was very poor. It was called tuna sandwich, which is truly borderline. The flight attend attendance seemed to be overworked and tired.

TAP‘s flight attendants seem to be among the least ambitious of all the international flight crews we’ve flown with. . When we left US and went to Portugal, and when we returned from Portugal, flight attendants were not very visible. Then did not offer frequent water breaks and when we had to go back to request water, I was almost an imposition. Meal quality was just average. The dinners were fine. Breakfast wraps were presented soggy.

Did not enjoy the meal provided. The aircraft was dirty. For instance, the screen seemed to have been cleaned with a dirty rag. Disgusting.

The business class seats were smaller and closer together than other airlines.

Boarding- Good Seat Comfort - OK Crew - Good Food - Mediocre On Time - Very Good

Didn't like much. Wheelchair assistance was almost nonexistent. No one at TAP check in process helpful. On the plane, stewards were not friendly and disorganized. Food was terrible for 8 hr flight. We were skipped at snack time and even though we tried to get attention using overhead call system no one even looked up at us to acknowledge. Being at the back of first section and by the lavatory we only were able to request when they came to pick up everyone else's garbage and they were nonchalant...no apology or even choice. The 1/2 half bread with slice of cheese was a waste. Deplaning was horrible but I'll blame lisbon airport for that. Plane left late at made good time still arrived about 15 behind schedule and for using remote deplaning and bus to terminal took another 20 min to gate. Those with connections were highly stressed. Took us 2 hrs from landing to get to ground transportation and exit airport. And that was with wheelchair assistance.

Bad boarding, threat to force bag check mid journey, lines, late, buses, more waiting awful end to end.

Check in was excellent thanks to the team at the check in counter. I was disappointed to see that one has to pay for coffee on the flight. This is the first time I have seen that after 60 years of flying.

Our steward Margarida who served us from Lisbon to Boston was absolutely fantastic! She deserves a raise. Conscientious and thorough as well as showing appropriate attention for every need.

Nice to fly out of Orly smaller easier to navigate airport. Being able to receive boarding pass well in advance of trip was comforting to know all travel was in order.

Liked. The check-in was pretty quick as they had 5 desks working.

Generally a good experience except for boarding in Naples on the flight back to London. We were all standing around for at least 20 minutes maybe longer as there was no seating.

Seats, WC,sizes for today's generation adults, and if technical problems arise a complimentary coffee, water nice for waiting one hours, the rest is perfect (pilot and cabin crew)

Boarding was smooth and quick. Flight departed on time. Equally evacuation upon landing was from both the front door and the back doors. Bags were on the conveyor belts before I got there. Excellent service.

The terminals are far away, be prepared to walk. Also, You climb stairs to the plane since there are no aero bridges. Boarding was haphazard not in multiple groups, so stand in line early. Hard to find place to stow cabin baggage if you are behind in the line. You can purchase food on the plane. There are vegetarian options.

First -the flight was late - more than two hours Second, not even a bottle of water at bord to give for free for this inconvenience. Three-at landing ive realised that I've lost one of my ear plug headphones and been very desperate to find it with my torch, the crew not helped at all more than that they asked to leave the plane as everyone did before me. This was the last flight from that day- extra 5 min for me with a bit of help from crew - would have bring a super review. I guess this days humanity disappeared!

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.

I had heard horror stories about Ryan air and was a little worried about my flights with them but I had 3 flights with them in Italy, Puglia and Sicily and it was a painless and smooth process. I was very happy.

Take off was great but landing is always with a bump.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

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.

main meals are horrible but then you dont fly for the food

It was good. Couldn’t Check in online and select seats

It was great. Enough space and room for legs . Great service to.

⭐ British Airways Review — A Journey of Highs, Lows, and Lessons ⭐ I recently flew Business Class round-trip from Boston to Mumbai with British Airways, and my experience was a tale of two extremes — from disappointment to exceptional service, and then back to inconsistency. Boston → London: A Surprisingly Poor Start My journey began on a disappointing note. On a 6-hour Business Class flight, I was surprised to discover that there wasn’t a single proper vegetarian meal option available. I was offered a few bakery items only after repeatedly requesting something to eat. The flight attendant shrugged, offered no solution, and eventually — quite literally — threw some bread at me after much delay. This was not only disheartening, it was extremely surprising given my wonderful Business Class experience with BA last year. I stepped off that flight genuinely hungry and had to make a mad dash to the lounge just to get a proper meal. London → Mumbai: A Complete Turnaround The next sector restored my faith in British Airways. The entire crew was warm, welcoming, attentive, and genuinely caring. A special shoutout to Phiroze and the entire team serving the Business Class cabin — their professionalism, hospitality, and thoughtful service were extraordinary. They truly embodied what makes British Airways a global leader, and I am deeply grateful for the experience they provided. This is the BA I know and love. Mumbai → London: A Strange Meal Schedule This sector was generally fine, but the meal timing was puzzling. Lunch at 10:30 AM — for a Business cabin — felt unusual, and most passengers, including myself, barely touched it. The rest of the service was smooth, but the scheduling definitely needs a rethink. London → Boston: Mixed Experience Again The flight itself was decent, but the Business Lounge at Heathrow for this leg was a letdown. Arrived during lunch hours: no hot vegetarian options available Lounge area: dirty dishes everywhere Even after politely alerting the staff, the dishes were ignored and left uncleared For a premium cabin passenger — and at one of the world’s busiest international hubs — this was disappointing. Overall Impression My journey with British Airways felt inconsistent — two great sectors sandwiched between two that fell short of the BA standard. When BA is good, it is world-class. When it misses, the gap is noticeable. I genuinely hope the airline takes this feedback as constructive insight. I continue to believe in British Airways, and I commend the outstanding crew on the London → Mumbai sector — they were the highlight of my entire trip. With a little more focus on vegetarian meal availability, lounge service, and consistency across crews, BA can ensure every Business Class passenger experiences the premium journey they promise.

We were in business class and I had seat # 1. This was a night flight and after dinner was served, lights were dimmed and I went to sleep. The crew were loud and noisy so I didn’t get much sleep. I expect the crew to enjoy themselves but would Appreciate some decency in staying quiet while the passengers sleep

Have travelled business class with other airlines who profess to be the best in the world. They can however not beat the service and comfort that BA provide.

Great on board entertainment Tasty food Cattle class obviously crammed but not as bad as shorter hall flights

Logan gate staff was unhelpful. Arrived early, come to find out the airbus scheduled was reassigned and I did not have a seat. The desk agent spoke to his supervisor who instructed him to give me a boarding pass to get up to gate area, he was polite. At the gate the fellow was sitting to the side with two other BA staff . I asked him if he could help me, his answer was” we are on a break, we are closed” then turned his back. I am almost 70, drove 4 1/2 hours to Boston and had been looking forward to this trip for 5 months. I have worked in service many times in my life and this is not how it is done. I eventually (1/2 hr) before boarding was able to get a seat. The rest of the flight experience was unremarkable.

The boarding process was chaotic at LHR and the seat was not as comfortable as other airlines....

Everything, every step of the process, from check in, to boarding, to exiting the plane was organized, efficient, and orderly. Excellent experience!

Very efficient boarding. Plane lready for take ooff10 minutes before time.

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.
