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.

Airline reviews

First, Delta needs more flights to/from Miami. Second, a 1000pm leaving at 1230pm is unacceptable from their biggest airport world hub. Another aircraft could have been used such as the aircraft scheduled to be used in the morning for that exact same route. Yes, I did get me there but the lack of sleep the next day didn't help me enjoy my entire trip since I was busy with activities during the weekend. This can be and is expected from Spirit (going bankrupt) and Frontier (despite they're nickel and dimers). But from Delta's World Hub? That's totally unacceptable!

Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.

Old plane and old configuration/seats but still comfortable for a morning flight

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

We were delayed, which I think had to do with air traffic control. Otherwise, everything was great.

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

The crew took good care of us. The flight from ATL to SFO is a longer one, and there were multiple beverage offerings. I like the 757's that Delta uses. Good airplane that is comfortable. I do wish Delta would separate Priority boarding from the better seats. I would gladly take a smaller seat in an open row than be jammed into Comfort just to get priority boarding, just to make sure I don't have to check a bag.

The flight attendant in first class was beyond rude and didn't care at all about her job. AND the gate agent was even worse than the flight attendant for rudeness. She was awful.

Cramped seating for me. Luckily it wasn’t a long flight

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

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.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

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.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

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!

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

The movies offered were great. Staff were very pleasant and very efficient.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very bad! They kept delaying my flight and wouldn’t do anything about it

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

Flight and crew were great. United didn't inform crew of immigration process which was disappointing!

Flight team stood out for perzonal attention, kindness at bright cheery attitudes at 8am. Very helpful.

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

AA delayed the flight for 3 hours and 50 minutes, but delayed the last 2 hours, 30 minutes at a time, so if we knew before, could have stayed at home and worked instead of being at the airport wasting time... The plane's crew was excellent, not their fault.

After arriving in Dallas, the aircraft taxied for an unusually long time and was unable to park at the gate, which caused a significant delay and made me miss my connecting flight. I then had to wait in a very long line to be rebooked, and I was told that no hotel or meal accommodations would be provided. What is even more unacceptable is that my luggage was mishandled and has still not been located. My suitcase contains important medications that I urgently need, and I have been unable to access them due to the airline’s mishandling. This situation has caused me considerable stress and inconvenience, and I need this issue to be resolved immediately.

RIC Staff was not enough. Elderly passengers had to wait 30 minutes to deplane, so we could board and still had to walk as no chairs were provided. And, passenger in front of my seat assignment rammed seat against my legs entire flight time. Was mildly bruised and left thigh still sore.

Liked that it was on time. Staff professional and friendly.

Things were delayed a little. But that didn’t affect my plans. It was fine. I was surprised it was so full thanksgiving day. The crew were friendly and professional.

I appreciated that it was on time, safe and professional. I didn’t like that I wasn’t in a place where I had a window at my window seat. It would have been nice to know that in advance. If it was mentioned in the ticketing, I didn’t notice it.

My flight was delayed about three hours. I got home at 3:30 in the morning very bad experience.

I like that the crew kept us informed but we moved back and forth from gate to gate before the aircraft arrived.

The flight was delayed multiple times, again no fault of American but again the extra cost, for everything makes it feel like a cheap airline! Especially when flights are outrageously expensive already

Horrible. Both legs of my flight were delayed more than 6 hours. No compensation, no screens on the plane, and the plane was not clean.

Although business class, the seating was really cramped. The food was so so.

Smooth trip no turbulence which is always a bonus for me lol! In cattle class so an element of being a bit squished (but not as bad as other shorter haul airlines) smaller plane than the one we flew out on and entertainment system wasn’t as modern but still definitely passed the time. Lovely crew x

I was attacked in the Miami airport and the staff did nothing. On my flight from London to Miami one of the flight attendants screamed at me and demanded I keep my seat in the upright position at all times during the fight so the man behind me was comfortable for the flight. I will never in my life use British airways again

Airlines have to stop assuming passengers bring entertainment. Provide it like you used to in business class and above!! N

I don't know about the others but the flight attendant that took care of us had the absolute wrong approach "how do we dare asking for water or anything else for that matter"

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Not my definition of first class. No leg room and barely any recline. The food was good. The crew was great. The comfort for the price I paid for London to Cairo was highway robbery. The Wi-Fi didn't work for me either.

Seat pitch is not enough to eat comfortably. When seat in front is reclined, your screen comes closer to your face. Ryanair seats are actually more comfortable.

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

The leg from Portland to Heathrow was great for a business class ticket. The BA leg from Heathrow to Lisbon was terrible. Basically coach seating with an empty seat between you and next passenger. Absolutely no leg room. Should not have been charged for business class and it was a 3 hour flight.
