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

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.

Awful. I told them to cancel my return flight and they didn’t then charged me +$800 days before the flight for a biz class upgrade bid. When I called to confirm cancellation and get refund on buz class upgrade they said I had to go thru orbitz and it was too late. Scammers. Beware.

Little leg room in business. I am tall and could use more.

Was a cheap flight and it got me to Portugal on time. For economy there was ample leg room and the flight attendants were pleasant and helpful.

Flight was packed. This was a very uncomfortable experience. Boarding process could be explained better. Despite recommending a window seat when travelling with a pet in the cabin, the seat in front of me had less space than the center and aisle seats. For Premium Economy, the seats were crammed with minimal legroom. I hate to think what Regular Economy was like. The cabin crew missed me at first when handing out meals. When my meal eventually came, there were no utensils. I'd originally booked to fly Business Class; those seats didn't look that great either.

First time and I enjoyed the trip…. Will fly again soon 🔜

Delayed flight because other plane was occupying the gate for longer than expected. Once we boarded the plane had to wait 1 hour before taking off. We. Almost lost our connection flight and the baggage didn’t make it. We had to wait two days to receive our luggage. Hope they improve the timing or work with the airport to get better service.

I’m still missing my bags. I’m soo frustrated

TAP boarding gate agents singled out Group A line to gate check all carry on bags …. Supposedly because of lack on bin space. BUT ALL OTHERS WERE PERMITTED WITH CARRY ON BAGS. Additionally so many passengers entering the plane after us were permitted carry on bags. And when the plane was fully loaded, there was a number of open spaces in the overhead bins. I WILL SEARCH OTHER OPTIONS BEFORE FLYING TAP AGAIN

Boarding went fast. Lisbon's gates are too small for the flights they serve.

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.

Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

Usual issues with flight delay. Perennial problem of travel by plane.

i didnt go this was a hacker booked this flight on my debit card !

Delayed almost 2 hours sitting on plane. No updates at all from flight deck and virtually no updates from cabin crew

Long delay resulted in my being unable to catch a train home and resulted in an additional £76 cost for an Uber

The flight arrived within 15 minutes of schedule. We hate the cattle-like boarding process seen often in Europe. After your boarding pass is checked by the airline staff, you wait standing up in an area with no seating for several minutes.

ontime and super quick boarding and disembarking. I made it in 6 min from airplane through passport control to the train platformin Cologne. Amazingly quick airport.

There plane had a technical pricken so we had to disembark, but the replacement aircraft was provided within one hour so there was not much delay.

Miserable staff did not want to be there. Very poor atmosphere boarding. Then just basic flight.

We were diverted to warsaw and there was zero information. We were just forced to disembark and off we go good luck the reat of the way. We all had to go our ways to find a way home!!!! Horrible horrible and it cost us alot of money to get a hotel and trains 4:30 pm next day.

Long delay was made worse by lack of information and long time in queue waiting for the plane to arrive

Blood contaminated tissue was stuffed to the back of the seat in front of us.

Great flight, departed only 10 mins behind schedule off the aircraft and through security in less than 15 minutes. Love flying from Cardiff so easy a quick from entrance to duty free in less than 10 minutes 😀

My flight was delayed 1 hour. My Mood was not great

Lord knows why they had us start boarding when the plane wasn't even there, staff weren't welcoming and the couple next to me travelling with a young child had a nightmare with the baby changing facilities.

LCY airport is an amazing airport and I love the flight from LCY to FRA with BA. Efficient, easy, comfortable and great luggage allownace with BA. I iused to fly predominantley LH, but the service and price - benefit ratio of Lufthansa has deteriorated a lot over the last 5 years. Whereas BA keeps an excellent service level with friendly staff.

Flight Attendant Karen Lynn was an absolute delight. She assisted in every portion of the services provided throughout the flight, aided with any and all concerns expressed by passengers, and even helped comfort an upset child who was one of five of a traveling family. This quality of service is what keeps me coming back to American. Thank you!

The airplane was old. Some things didn’t work out of middle seat was broken. The rest was OK.

The worst, flight cancelled because the aircraft was not full. Heathrow ground crew totally not helpful and arrogant. Lady proposed us flight with 40min layover instead of direct and said it is our problem of course she was unable to do anything as everything was beyond her control she claimed. after calling on hotline another flight was booked. Flight was cancelled last second so we could not take direct from Zurich but we had to stay overnight in London.

Very quick boarding. I was surprised we only got a small water and small thing of cookies, everything else was for purchase. No entertainment. Crew was excellent though.

Flight delayed in terms of boarding and Kayak was great in updating but the team on the groping at British Airways were really poor

A basic tea/ coffee and a snack could be provided especially for long distance flyers.

The information in the airport, and the app was different. Be aware. Different terminals in Stuttgart, so we had to walk a lot. It's a small airport so it wasn't a big deal, but it was ludicrous to see the error in the app.

Flight was delayed and there was boarding pass and flight information errors resulting in confusion and stress

Food was terrible , crew were excellent , IFE was dire . Overall comfortable seat and cabin. Nothing special .

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.

4 hr delay and only told less than 2hrs before. Only given water and nuts on the flight as complimentary service. Left to wait in rain before boarding.

To be honest I did not like anything. Communication to why my flight was cancelled mid air 2 and half hours into my flight. Customer service desk were not helpful with providing information or a solution on what can be done.
