Top tips for finding cheap flights to Portugal

  • Check out one of the several lounges at Hartsfield Jackson International Airport (ATL) if you arrive early and have some free time before your flight. These sofas were designed with relaxation and comfort in mind. In a quiet area away from the terminal, passengers can unwind as they wait for their flight. There are many lounges, including the USO Lounge, A, Delta Sky Club, United Club, American Airlines Admirals Club, and The Club at ATL.
  • For the duration of your trip to ATL, you are free to leave your car in one of the airport's parking lots. They provide you with a selection of secure and practical parking solutions. Make arrangements for airport parking by calling well in advance of your travel date because there is frequently a wait.
  • There are three international airports that serve as your airports of arrival in Portugal. These are Lisbon Humberto Delgado Airport (LIS), Porto International Airport (OPO), and Faro International Airport (FAO). All of these airports serve international travel. To go to the airport that is nearest to your final destination, however, is what we advise.
  • Several different transit options are available to travelers landing at any of Portugal's airports. However, consider hassle-free automobile rental if you wish to travel around Portugal. Centauro, Hertz, Europcar, LUZCAR, CARO car rental, and BravaRentaCaroffer vehicle rentals at the airport.
  • The airports in Portugal offer the best accessibility for passengers with limited mobility. The check-in area and arrivals halls both have accessible restrooms, and the airport provides wheelchairs for usage throughout the terminal. Contact your airline for additional details.

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

The flights are constantly late anymore, and they won't even give you a glass of water on the plane. For years, they were able to do a service on this flight from Atlanta to Knoxville and Knoxville Atlanta now they say it's too short of a flight. You can't even get a quick drink of water.

Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

The crew were efficient. The pilots seemed professional. It was a bit chilly in our seats. The sheet provided weren’t very helpful.

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

Delta does a great job with entertainment and free wifi. I can still be in touch with my colleagues while in the air.

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

Everything was great. The only issue is unfixable. Seats are too small. 😁🤪

I had a terrible experience. My flight got delayed from Atlanta to Chicago on Monday April 6, 2026, and that led to me missing my next flight to Brussels. United Airlines didn’t provide me with any accommodation for shelter. I had to sleep at the airport in Chicago. The next flight I was put on didn’t leave until the evening hours of Tuesday 4/7/2026.

Just a bad day to fly. Flight was delayed from scheduled 6:50 pm departure to 8:50 pm. Combination of factors mostly related to weather at the destination airport (which is where the incoming flight originated) which delayed the inbound flight over an hour. Once on board, we taxied but had to hold again on the taxiway for 10 minutes or so. We did not get wheels up until after 9 pm. The flight was smooth but about 18 minutes from our destination, we had to hold for several minutes more due to weather at ORD. We finally landed at ORD about 11:08 pm (accounting for the time difference, that was about a 3 hour delay from our scheduled departure time). It felt like we were never going to get to our destination. But the flight crew and attendants were very good. The movie selection onboard was also very nice. Got to watch half of a movie just during our taxi from the gate at ATL due to the delay!

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Gate agent at Frankfurt was terrible. She denied PRE boarding even as it was printed on the boarding pass. Refused to look at the boarding pass and literally shouting for no reason. Frankfurt airport has horrible and rude staff who avoids trying to answer any question at all. Overall, horrible experience.

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

Cramped seat even in economy plus seat 10A. Over booked flight, no space for the bags

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Great onboard crew. Boarding was a zoo, I got in line before pre boarding in Group 2, still had my bag force checked. WiFi was glitchy all flight. Seat and bathroom are both tiny unless you pay $$$ for first class.

The passenger in the row in front of me was listening to a political speech on his phone at full volume with no headphones and it was disturbing all of the passengers around him for several rows. I asked 2 of the flight attendants to speak to this passenger but they only shrugged. It was obvious that they were afraid there might be conflict and would not say anything. I had to take it upon myself to tell the passenger that he needed to turn it off or wear headphones as it was disturbing everyone around him not wearing their own headphones. I was very disappointed in the United flight attendants.

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

Hate their old flights, boatding, food and services. Very poor quality

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

This is my second time to fly this year with Lufthansa and both times they dropped the ball. My ticket was very cheap and l would not be honest if l said that l had some high expectations for that price. Fly delay 6 hours. Screen in fey seats around me didn’t work. Food for dinner was ok but breakfast was so poor. We had connection in Frankfurt for Vienna. Because of delay they gave us fly with 30 min layover time. We got to Vienna but our baggage was late of course. Long story short it took us almost 24 hours to get to the final destination. Very bad experience

Email noting gate change was good. Very bad: credit card machine broke down to charge for a checked bag. Lady at the counter read my credit card number OVER THE PHONE to a woman in Germany. Very insecure!!

Dinner was good by air travel standards but breakfast was too light and heavy on carbs/sugar.

Flight crew was ok but in terms of child-friendliness, no one beats KLM and even most US carriers are better. Economy class got smaller and smaller over the years but still better than AA or Delta. Food was pretty good and pre-boarding with our infant was available.

Our flight got canceled by Lufthansa just 24 hours before the departure. We lost time and money because of this

Selling food instead of offering it as complementary with the excessive price, is pure greed and not comptitive at all.

Lufthansa boarding is certainly easier and organized, staff is courteous always. But they can offer better food and definitely better selection of movies onboard. Also, all airlines offer two baggage’s for an international trip except Lufthansa. That needs to be reconsidered. Overall, a good trip. Thanks!

They could not check me in through to my final destination, even though it was through a partner airline. We departed the first flight 1.5 hours late, which gave me 45 minutes to run around the connecting airport trying to figure out where and how to get my next ticket. Very unpleasant experience and do not want to fly with Lufthansa again.

It was not British Air, we were put onto Air Portugal for our London to Lisbon leg.

Very please with the seating that the Kayak staff booked for us!

The cramped seats are cruel and unusual punishment and may violate the Geneva code.

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience

Very good crew. The seating in economy plus was excellent, and I slept most of the way. The diabetic meal that I requested was almost tasteless--about a 2 on a ten-point scale.--so I ate little. And why bother serving dinner to fliers at midnight?! I had eaten a meal at the airport six hours earlier. A good breakfast would be better.

They denied us boarding on our scheduled flight and experienced significant disruption to our travel plans because of overbooking the flight!

One of the worse flights. Departure was delayed by an hour. Boarding was disorganized. It was freezing on the plane. The crew was not very helpful. One of the flight attendants was literally marinated in some awful perfume,. And the food was uneatable, both dinner and breakfast.

Horrible service. Lack of courtesy and professionalism from some cree members

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

I couldn't get my luggage after arriving to my final destination. I don't know if it's lost or whatever. I in stress right now
