Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

Made the Atlanta to Pittsburgh trip many times, with Delta no issues

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Food was terrible Not many options Stewards dont care Delay

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

Flight was ok. Food on way there great a pork dish way back tuna and pasta was not good. Flight attendants were great. Wish they had more soda options like ginger ale seltzer water. Good experience overall. Worst part of trip was car rental Klass company car broke down we were on side of road late night 4 hours awful awful experience all they wanted was 500 euros for help to come absolutely horrible experience we were scared side of highway they offered zero help!

Coming from USA it was nice to be treated nice for a change. Even though our flight was pretty short we were served breakfast. On time flight with very caring staff. Please teach American carriers how to treat people.

More space between seats and in bathroom. I don’t think there was any entertainment offered. If there was, I wasn’t aware.

Every meal/snack included something with ham/pork - even the cookies had "swine fat" (which we only knew because we thoroughly checked the ingredients). There were no vegetarian options, and we had not been given the option of pre-selecting a meal when purchasing our tickets or checking in. That made for a VERY long flight. We were fortunate that we had brought our own snacks as back-up.

Waited in line for hours just to get a boarding pass which would not print at the kiosk or load on my iPhone. Waiting again for about 45 minutes to get through passport control. Poorly managed airport. The flight and crew were great and the flight was very comfortable.

I booked and paid for my original flight with E-Dreams. Also made seat selections. Got an email a few days later saying my return flight had be cancelled?? Called E-Dreams and they said it was the airline that cancelled (Sato)? Told to rebook the return flight myself? Cost was double the original flight and was booking me on the same flight as I originally booked?? Called back, the agent agreed to cancel my flight to the Azores and AGREED to a full REFUND. The agent advised me to re-book the flight on my own. Did so and ended up with the EXACT same flights as originally booked?? Have only received a PARTIAL REFUND. Still out approximately $300 dollars?? Is this a SCAM. How do I get the remaining REFUND?? Regards, Brett Parry

I wasn't able to log into the onboard wifi entertainment, but I fell asleep on the flight anyway.

Cons: "Paid for business and Seats did not recline, not was there any entertainment provided from a flight from Lisbon Portugal to Boston. This was not a business international flight although it was sold and advertised as one. Awful."
Cons: "I paid for business and there were no TVs or any entertainments from Portugal to Boston on Airbus 321. The seats barely reclined so basically I was charged for business and got a premium economy seat. They do not have a business section, never flying with them again."
Pros: "Cheap aitfare"
Cons: "On time takeoff Better food Television screens to watch movies Better selection of movies"

I liked the friendly crew and desk staff, all very helpful. I was surprised and a little annoyed on my outbound flight from LGW to MCO as I had prepaid and booked my seat, which was all correct at check in on my boarding pass. when I got on the plane someone was in my seat ! I was moved to another seat. The food choice is quite limited and I feel that an option of a muffin for breakfast snack would be welcomed, not everyone wants egg or bacon wrap. The choice of entertainment is good, plenty to keep you busy on a long haul flight. I liked the option offered to have the cabin bag checked into the hold, it saved me as an older, lone traveller lifting my case into the overhead locker or finding there was no space.

The only comment I have is why do you sell snacks on board? They should be free. When we take domestic flights here in US, our snacks are free. Also, please communicate with me in English. I received so many emails way before my flight that were in Spanish that I had to ask my son to interpret for me. You should be WELL AWARE if the customers you are communicating speak the language, it does mean that we speak and understand Spanish because we are traveling to Spain, NOT NECESSARILY! Thank you!

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Service and food are good. However, main cabin with the extra cost one pays could be better. I don't see any difference with the rest of the seats in the regular category. The seats are too close to the ones in front. For short flights it is Ok, but for long ones there should be more space.

Fast check in, easy to navigate, crew were very good, the plane was delayed due to a previous flight and I found the cleanliness a little lacking but overall it was fine

My wife and I paid for seat selection to be together. My wife and I were on separate rows and the excuse they gave was they changed the plane. Also, I have celiac and asked for a gluten free meal in the ticket profile which they did not have.

I’m hoping for WiFi included. Everything else was very good

Rude security cunts. However the lady that issued my boarding ticket when I was flying back from New York was lovely & helpful!!

Appalling! The flight was delayed by 3.5 hours and the American Airlines staff at the airport where nit very helpful. Once boarded, the flight crew were unhelpful, the food was poor and the aircraft was tatty.

I called prior to flying to confirm our baggage allowance which was 5 bags. On our outbound flight thee were no problems. On the return flight we were charged for each bag totaling $400! We are working with customer service to resolve the issue.

I thought Miami's airport was very disorganized during the Boarding.

Very efficient boarding - other airlines could learn from them. Friendly, efficient crew. Red eye flight, so dinner meal was irrelevant. Breakfast could have been more substantial. Seats reasonably comfy.

People seated in exit rows should have designated overhead space

I have been flying internationally for most of like. My first trip with TAP- wonderful! I look forward to flying with them more frequently in the future!

Larger seats on this plane made the ride reasonably comfortable. Our next flight, from Lisbon to Copenhagen, was inconsiderately tight and stressful. The seats were smaller, space between rows was very limited (no button or mechanism to even slightly incline anyone’s seat), and leg-cramping under the seat in front. Just like sardines in a can. Really felt for all the tall Danes on the flight. Their knees were pressed against the seat in front throughout the flight.

Flight was 2+ hrs late boarding. Delay updates were nonexistent. Boarding Gate change was by word of mouth.

The plane was modern and clean. TAP staff at the airport as well as the flight crew were professional, friendly, and helpful. Overall, a great experience.

The airline made last minute changes to our business class seats splitting our family of 4 with young children who had pre-booked a row of 4 seats. The seat was also dirty and sticky. Our pre-ordered child meals were also not available. :(

Awful experience all around, misleading booking led to disgraceful baggage charge at gate. Tiny uncomfortable seats with little drinks served in small paper cups filled halfway. Difficult to use bathrooms the whole flight and now on the way back we’re stuck in Lisbon a day later because of a diversion on our connecting flight, I will never fly this airline again.

I suspect that there was an item pilfered from my bag at the TAP automated check-in counter on March 26th at Heathrow Airport around 11:30am. I think that the employee assisting me with my bags took something out of it when I was not paying attention because today, March 27th there is a notebook missing. Please check the camera to see if indeed this occurred. My description: Male, African Decent, 5'8, 180lbs medium build, wearing trousers and a jacket. Employee description: Female, Indian Decent (guessing) 5'7, slight build. Flight 1359, London to Lisbon.
