To definitely go to the airport more than 3 hours ahead of your flight time because Lisbon airport js very poorly designed with no self checking devices and shortage of staff to assist you. Long long lines for going through security, 3 hours or so just for that. Many flights were missed because of that so go at least 5 hours before your flight to be able to make it

The Lisbon airport traffic was such that I could not get an Uber to the airport. Take that into account or use the Metro which is cheap, easy and quick. I also found Lisbon Airport to be more difficult to progress through than JFK. I had thought JFK was difficult but once cleared through the TSA screening your in . Lisbon seemed to have more layers of difficulty.

For any flight that's part of a Multi-City flight plan, don't miss it. Otherwise, all your remaining flights on that plan will be terminated.

There are other airports like Seville, Barajas, Orly, Charles de Gaulle, etc. that connect the planes directly to the terminal. No need for the extra tour bus.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

Awful. There was an unexpected delay of nearly three hours because there were not enough flight attendants. I understand this is likely due to FAA regulations; but in that case, Delta should coordinate with smaller airports such as RDU to have extra flight attendants on the ground and "on call". In addition, this was the second 2-hour+ delay to Boston on this route in one week.

It was strange that the flight attendant was so adamant about having phones turned to airplane mode that he was calling out names from networks shown and waiting until they were all gone. I've never experienced that before, and after already working through an hour+ delay, it felt tone deaf. I take dozens of flights per year and have never experienced anything similar.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

Your survey needs a N/A option. I didn’t use the entertainment or eat food.

Terrible. I was bumped off of my original flight and spent the next six days fighting to get back on it. I lost hours of my vacation trying to get this situation corrected.

Boarding was tough as we had to take a bus out to the plane and walk up a lot of stairs. Difficult with heavy carry-ons that said I got an entire empty row of seats, which was excellent for an international flight. Food was very mediocre but happy with the comfort so not complaining.

Delta is a cut above the others in customer service.

Tasty snacks. On-time departure and early arrival. Luggage arrived quickly at the carrousel. The only negative was a man behind us that was heavily inebriated. He was served 3 double drinks during the flight. There was no telling how much he had before the flight. He was so out of it that he spilled a drink and broke the heavy liquor glass on the floor. I don't believe he should have been served so much alcohol on a two-hour flight.

Checkin was easy, boarding was organized, employees friendly and nice. Was a lovely flight.

The flight crew was exceptionally friendly and helpful. Also the seats were comfortable and roomier than many other airlines.

Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

They lost my bag and I still haven’t received it yet

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Boarding was a disaster being moved by Air France by bus to the plane. The plane should have been at the right gate.

Flight was late over a hour just like the first one. WiFi was down.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

They charge me for luggage which is was included on the ticket

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

Lots of legroom on the flight. No interaction from the staff at all on the plane. They only attended to the First Class passengers. There was no entertainment. Security I was body scanned even though I hadn't set off an alarm, my father-in-law in his 80s, was stopped and subjected to a through body search, told that they would have to place their hands in intimate places. There were several border guards present, and as we walked off we could hear the TWA officer talk about the procedure as if he was training. My father-in-law was a little upset about the whole process. A kind explanation would have been more acceptable, and it felt dehumanizing to him.

Needed a 6 hour lay over in Atlanta. How can this be avoided ?

Security area in terminal 3 needs to be made much nicer. Less claustrophobic and use of glass and big ceilings wouldhelp

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

Our flight was delayed 2.5 hours from Lisbon to DC so we missed our connection to Seattle that would have arrived at about 9 PM. The agent initially said we had to stay overnight in DC and there were no other options to put us on to get us to Seattle. While on board I discovered a flight via American he could have put us in but by the time we arrived in DC that was sold out. We were then put on a flight to San Francisco that was also delayed then arrived in San Francisco and our flight to Seattle was also delayed so we ended up not arriving until 2:15 am. Our son could not pick us up so we ended up having to pay over $100 to Uber home. This is the second trip with United that the flight has been delayed causing us to miss an evening in Las Vegas and we were given nothing.

I paid $7,000 to fly round trip to Porto. I thought it was for business class. But on the leg from Miami to Newark, and again from Newark to Miami, i was in coach. One time in the middle seat of coach. From Newark to Porto I was in business class as expected, and it was fine. I fly to Portugal once per month, often paying $5,000 for business class. Usually i fly American Airlines. I'd be happy to fly more with United Airlines. But my experience was disappointing because i was put in the coach for almost half the flights.

Lufthansa was great from Lisbon to Frankfurt. The United Airlines flight from Frankfurt to Denver was very cramped. In that tight space, when the seat in front was fully declined I could barely move. I'm a fairly small person, I can't imagine what a larger person would feel like.

I would have liked an opportunity to move to a different seat ( even would have checked in my hand luggage)as I had health issues where I didn't have to clamber over the passenger next to me to for toilet use/ movement [ She was a highly unpleasant neighbor to sit next to]. In addition, I found that my European phone plan had run out of data and so I was not receiving emails from yourselves on airport wifi to be able to check in online and verifications difficult as did not accept the ticket number I had. I asked for an extra blanket but was told there was none. Then I saw other passengers receiving them. I couldn't eat the food and asked for snacks : Stewardess said " on the way" but they did not bring. The best bit was the check in process in Lisbon. Very efficient. However, I did not understand why we had to collect our bags at Washington then go through customs again. It was not explained. I also with my leg and health issue had approximately mile walk to the gate ( which then changed) . There appeared to be no moving walkways or help provided.

United left one of our bags back in SFO but that’s not my real complaint. The complaint is how it all went down. So we checked in the day before online and were told we could use the quick drop for luggage. So the next day I used baggage quick drop curbside at SFO. The agent mistakenly didn't tag my bag as he put my bag on the conveyor belt untagged. We immediately alerted him he had not tagged the bag. I walked with him to the baggage service office to find my bag and tag it. We waited outside the office for 10 mins. He came out and said everything was ok and the bag was going to be tagged and on my flight. We received a text that one of our bags was on the flight but the other was not. I alerted my first class flight attendant immediately upon boarding the flight. She was helpful and said she’d get it sorted out right away. She called over the gate agent. The gate agent used my bag number and looked over information on her device. She said my bag was on the flight. The flight attendant was standing with her, looking at the device, and also said “yep it’s on the flight”. During the flight the flight attendant made reference to how reassuring it must feel knowing the bag was on the flight. Upon arriving to IAD we received a text that my bag was not on my flight. The text said my bag would arrive to my final destination LIS 24 hrs late. I understand that mistakes happen. I was totally ok with my bag mistakenly not getting tagged at the quick drop. I was fine with walking down to baggage services to tag my bag. But, what I am not ok with is that the United staff said they fixed the mistake two different times, assuring me twice that my bag would be/was on the plane…and it wasn’t. I expected better attention by the employees, for them to do what they said they were going to do. We also spent extra money to upgrade our seats to first class, including the entire return leg from Lisbon to San Francisco because we wanted a smoother and more relaxing travel experience. Our money was not well spent. We will not be using United for travel going forward.

Checked my bag despite paid the seat upgrade and there was plenty of space available in the overhead bin.

The flight crew was fantastic. The flight attendants were incredibly considerate, kind and attentive.

One of the best flying experiences I’ve ever had.

The flight from Lisbon to Newark was much, mush better then flight from Newark to Porto.

Web site needs improvement Plane was clean and modern Lay Flat beds were hard and not to comfortable (business class )

Overall, everything was fine—the service, the food, and the entertainment—but the boarding process in Lisbon was a total mess. I’m not sure I’d fly with TAP again. It’s absurd to have to pay for good seats at the front of the plane only to board last; the overhead bins above your seat are likely already full thanks to passengers who boarded earlier—even though they might be seated at the back of the plane. I will think very carefully before flying with TAP Portugal again; it seems to me that they need to review their boarding process. I understand the logic of filling the plane from back to front, but the seats at the front are more expensive. Horacio Rodriguez

Boarding was delayed by one hour because cleaning and catering crews did not board the plane in time. Take off was delayed for another 40 minutes because of "rush hour scheduling". Vague descriptiion. My in-flight entertainment system was stuck initializing. The flight attendant indicated that they could not reset it without resetting everyone's system. Overall, a miserable experience.

Better leg room than expected in economy. Nice crew. Adequate bathrooms. Seat cushions a little thin, but recline well and have adjustable headrests. Best value. Liked having nonstop from ORD to Lisbon.

Excellent! Flight left a bit late but overall a pleasant experience.

On both flights, TAP Air Portugal messed up the seating choices that I paid for. They acknowledged that I had purchased seating, that they were errant in ensuring my choices, but told me nothing could be done about it. When I asked to be refunded, I was directed to "talk to someone from Air Portugal" Mon-Friday, and then I was dismissed. No help, no phone number provided to me. I was very annoyed both times and feel cheated.

Business class seats aren't comfortable. Food was not good.

Didn't make announcements during boarding, flight attendant seemed annoyed when I asked for water. Too many hours between flights. Confusing check in at the Lisbon airport.

Delayed at the beginning and the end and almost missed our connection

The crew was great. There was a big guy sitting next to me who was hanging over my side of the armrest the entire time. Maybe some information about "Be considerate of your neighbors, this is tight space, be kind". The breakfast sandwich was not appealing at all.
