I truly love flying with Delta. They have always treated me with the upmost respect

Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.

Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.

Non stop on long haul is the way to go. Great experience

The aircraft interior is old and tired on this aircraft. The entertainment system never worked despite the crews attempt to reset the system.

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

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

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

The food was great and the service and attitude was amazing!!

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

It was an OK flight with below mediocre service by their flight attendants

7 hours delayed due to operational issues on United’s end. Basically laziness.

Short flight but an "eager to help" crew made the journey more enjoyable!

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

Staff was rude. Didn’t give water for 2 hours. Worst service

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

This flight left about 45 minutes late, and arrived about 45 minutes late, which was enough to make us miss our next flight and trap us in Dublin for 24 hours!!

I was so grateful for the kindness of the crew. They made a long trip very pleasant. Food was delicious. Many movie options

Fast and sensible boarding was absolutely amazing. But extortionate wifi and seats that barely moved, making me unable to sleep, didn't do a lot of favors.

I liked the front row seats. A lot of leg room. The check-in window needs to be longer

The actual flight experience was great. The handling of my luggage was terrible. First, I had to check in at the airport and wasn’t able to check in online because they booked me with a partner carrier in the U.S. that was incredibly inconvenient. I was also told that I would have to check in again with the partner airline in the U.S., also incredibly inconvenient at a large airport. Second, when I was at the counter, they did not tell me my carryon was too big. I only found that out when I tried to board the plane. I don’t know that it actually was too big though. It’s a standard sized carry on that I’ve never had issue with on any planes before. They assured me my bag would be checked all the way to my final destination. Due to flight from Paris to Dublin being delayed, I was rebooked on a different transatlantic flight to the U.S., which resulted in a different connecting flight to my final destination. My luggage was rerouted and I was assured it would be at my final destination. When I got to Newark, I received multiple phone calls alerting me that my bag was across the airport at a different terminal and that I needed to go pick it up near the baggage carousels. In the Newark airport, every terminal has its own security checkpoint. Leaving any terminal and entering another one requires a security check. At this point, I had to go through security in Paris, then again for US customs and pre-clearance at Dublin, then a third time when I had to change terminals at Newark for my connecting flight home. It was at this point I received the call that I needed to retrieve my bag from literally the opposite end of the airport and go through security A FOURTH TIME. These was no notification that I needed to do this before I went to the gate for my final flight. It took me an hour to go do all this, after I had already been traveling for 19 hours while sick and should have been home already were it not for the delay of my original flight. I retrieved the bag. My carryon became a carryon again and fit just fine on the last plane, by the way. I would also like to mention that my TSA flight information was not included on my ticket, so once again, I had to go to the airline counter to get my ticket corrected and reprinted before I could go through security and try to save myself time. Finally, I have celiac disease and prefer not to eat meat. There was literally no food I could eat on the seven and a half hour flight across the Atlantic. When the flight attendant woke me up for dinner (I would have preferred to sleep), I asked if there were any gluten free options. I was told the only option was chicken. I begrudgingly accepted because it was the only option, hoping anything else in the meal could be eaten. There was plain rice and a few green beans. The side dish was teriyaki vegetables containing gluten. There was a piece of bread, containing gluten. There was a custard, containing gluten. I could eat literally nothing except the very small amount of rice and green beans. When the same flight attendant came around again, while I was sleeping, a sandwich was placed in front of me, again food I could not eat. And this was after I got to the flight to find that my newly assigned seat on my transatlantic flight had been given to someone else! It’s like nobody communicates over there. This airline has the worst logistics of any airline I have ever been on, and I travel frequently. Dear Aer Lingus, DO BETTER.

Dublin airport is big and US Customs and Immigration screening officers are is part of the process there. This eliminates screening upon arrival to US, however should be taken into consideration when playing your transfer. After all, pleasant experience enhanced by draft Guinness and Irish coffee at the buffet area near the gate. We loved boarding by the row, back of the airplane first.

A caveat, we flew during the ransomware attack that hacked the boarding and luggage tracking systems. I wouldn't ever be angry at the employees for that, but I WOULD be (and am) angry that communication was incredibly poor, that we got few live updates, and that the employees seemed uninformed and ill-equipped to handle the situation. Clear, honest, open communication and instructions would have benefited the situation. Unfortunately, there were literally no gate agents to talk to, no airport employees to direct people, and no clear signage (the app pretty much said "we don't know what gate your flight is."). Beyond this nightmare, the security was the usual dehumanizing circus of "Security Theater" which is... as we all know... only for show and completely useless. All three airports on this journey dropped the ball so hard. The flight industry can do so much better. Aer Lingus can do so much better.

Baggage fees are deceptive! When I booked this flight, I purchased two tickets and had indicated that I wanted one checked bag. That increased the ticket price by about $100 PER TICKET!. When we went to check in, I was told that I could only check ONE bag, even though I had purchased TWO tickets. I had to pay an additional $50 each way for my wife’s bag. In my opinion, I paid twice for her bag.

Too hot. Asked for an extra glass of water and was ignored. Asked to sit in empty seats that were open because it was so hot and crowded and was denied and the seats were empty the entire flight

Terrible leg room - I’m 5’3” and my knees were touching the seat in front of me. When the person sitting in front of me leaned back, there was about 15 inches of space between my head and the TV screen which made it awkward to view movies. Last year they had decent food, but this year the only tasty item on the trip was dessert.

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.

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.

The flat beds. Other than that, the place was not clean.

Moved me away from my family and refused to fix it.

I have always been pleased with their service. Would not change a thing

Seating and food was the worst we have experienced in 35 years of traveling for both personal and busines .
