WiFi only works on about 75% of my Delta flights. I rarely fly SW, but their WiFi works 100% of the time and is easy to connect. On my DL flight from DCA to BNA today, I try to connect to WiFi for about 30 minutes, but I gave up. I have a lot of work to do, and I lost two hours today. Very frustrating.

dropped my bags at Seattle Delta curbside. 1.5 hours before departure. one bag oversized made it. the other was left at curb and mishandled. poor communication from delta in sjc baggage claim. No internet on flight and food choices in business are horrible. You are forcing us to fly Alaska which is shockingly better than the Delta experience. that is a low bar.

attendents were rude and the boarding was disjointed and poor

Great flight. Thank you for the upgrade to first class.

Gate agent in LAS named Juliett should win an award for excellent customer service.

13 hour delay stuck in Detroit and missed a day of meetings. It was terrible

Flight was delayed and not a lot of communication on why until we got on the plane.

The seats were great and the service was even better. Thank you!

These Delta 717 jets are ancient. No entertainment and you have to pay for WiFi that barely works and goes in and out the whole flight. Delta should be ashamed flying this garbage.

My seat was changed without my consent. It wasn’t a major deal but annoying.

Boarding was extremely efficient; I appreciated the back-to-front loading strategy. The instructions from staff were very clear and thoughtful, and they were friendly and generous with service. In-flight entertainment was top-notch.

The check in crew were so friendly and attentive. Probably the best in my experience and I’ve been flying at least four times a year most of my adult life. Very considerate and I appreciate it.

Absolutely the worst at baggage handling. Our baggage still has not been delivered. They couldn't find it in Dublin then when we got to Edinburgh they said the 2 bags were sitting in Dublin. After spending an hour filling out forms at the counter. We left for our hotel, bags arrived in Edinburgh at 505pm using my satellite tracker. Tried calling the numbers provided, no answer to their 24/7 service. Next morning the bags are still sitting at airport, no movement. Called different number provided by hotel in Sterling, the said it's souly the responsibility of the courier service now and they couldn't help. Completely ruined our travel plans, we must find clothes to purchase today instead of going to the museums we had purchased tickets for. This loss is costing us thousands in already paid hotels and services. No one takes any responsibility. I'll be contacting legal services on our return. We will never forget and I'll be a social advocate to avoid using this service.

I was disappointed with my experience on my Aer Lingus flight from Denver to Dublin. One of the biggest issues for me was the attitude of the cabin crew. They came across as cold, unfriendly, and unapproachable. There was very little warmth or friendliness, and I rarely saw anyone smile. I did not feel that the crew made passengers feel welcomed or cared for, which makes a significant difference on a long international flight. The cabin was also extremely cold and uncomfortable. What made this more frustrating was that we were instructed to put everything, including our blankets, underneath the seats at certain times rather than being allowed to keep ourselves covered. Considering how cold the cabin was, this was particularly uncomfortable. I also did not appreciate the tone used when giving some of these instructions. At times, the communication came across as unnecessarily loud and abrupt rather than polite and courteous. I understand that cabin crew have important safety responsibilities and passengers need to follow instructions, but those instructions can still be delivered in a professional, respectful, and friendly manner. Unfortunately, the lack of warmth and hospitality from the crew was the most disappointing part of my Aer Lingus experience.

Cabin crew was one of the worst in memory. Poor in delivering service - in some cases skipping it altogether. Someone in baggage handling managed to steal my electronic bag tracker from Apple.

I buy ticket from you and when I go to the airport aer Lingus they tell me you need travel visa for Ireland for one hour travel so when I buy tickets there no requirement I need transit, visa or not so when I try to cancel my ticket or change my ticket, you guys say there is no refund so you u guys take all my money which is very disappointed

The aircraft was clean and relatively comfortable- for an aircraft seat. The entertainment was good. The food was terrible, especially the “breakfast “ which was a cereal bar, and just not good. The crew were amazing, professional and no complaints there. The food was so bad, I know for my return, it will be inedible.

Awful customer service. What you are told 100% depends on who you talk to.

I love flying with them, the long-haul was fantastic. The short flight from Dublin --> Switzerland was horrible though. Most narrow seats I ever had, first and only time in my life I couldn't even close the seatbelt in seat 1A which was very embarrassing so I had to sit in the middle, because that seatbeld was 20cm longer. No idea why seat 1A would have a much shorter belt, it's just ridicilous. Also I hate the fixed seats, way too narrow.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I purchased a Polaris ticket. The plane did not have the lie flat seats - I was not notified. I actually can not believe they traded a dif plane and did not notify me or refund monies

Not so good. Crew was not as attentive as they should have been especially if flying business class. Only offered dinner 2 hours after takeoff. My flight attendant seemed overwhelmed. Pushed my help button but no one came. I explained everything on my previous review.

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

It's not United, but TSA security at Terminal A in Newark is a disaster and seriously makes me consider switching to flying out of JFK. The touchless TSA pre-check had a line of over 50 people and the bag screening was so slow that it limited the flow of people through the facial recognition process. It is the only airport that I frequent that has this issue and makes me reconsider whether I should fly out of Newark given the wasted time and frustration it causes. As I said, it is not a United issue but will impact United if people choose to stop utilizing Newark airport because of the poor experience.

I initially boarded in a very comfortable and large plane and was told there was a mechanical issue with a waste receptacle. We sat on the plan for a good few hours, then were told we can deplane and that we would take off shortly. Delays continued and four hours later my flight was cancelled, and I had to quickly rebook another. The flight I rebooked was also delayed, and I when we boarded, I wound up on a small plane in a middle seat for the 6-hour journey and it was extremely uncomfortable. No issues with the staff in any way, just the overall experience of the delays, cancellations, and downgrade in comfort on such a long flight. It is significantly impactful on how you feel post travel and I was exhausted and sore from the experience.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

Flight cancelled instead of leaving Friday am now, maybe, leaving Sunday

Check in was chaotic with only one counter for business class and first class. The luggage conveyor belt at JFK airport was broken so the flight departure was delayed which made the flight stressful as I had a tight connection. Although the captain said they could make up the delay, they didn’t do so.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

The plane was FREEZING COLD. Like I was wishing I'd brought gloves. Is this how JetBlue sells more blankets? Other than that, all fine. Crew just as nice as usual. A flight attendant asked (who? The pilot?) to have the air turned down for a great number of passengers who were as cold as I was. They (again -- who is "they") did not.

Unacceptable pre-boarding ticket issues. Paid for and reserved Mint seat approximately a month in advance. Checked in to flight in Mint seat 24 hours before flight. Shortly before flight, was bumped out of Mint entirely, even though other Mint seats were still available and for sale. Was told it was "operational", however seats were still available/being sold. Got to gate and they could not explain it, but the gate agent was able to put me back into Mint (however to a different seat). Nothing proactive done by Jetblue, I would have been bumped had I not arrived at gate early enough to have a helpful gate agent rectify. No explanations from Jetblue.

Great. I was in mint class. Security was spectacular. A lot of room on the flight! And the WiFi worked this time- it didn’t work the last time and I am on a business trip so that was a problem.

My sons tv wasn’t working and they didn’t give him a kids meal I have to request it prior and no one told me!!! Then the 2nd flight they split us up. My two year old can’t sit alone on the plane hello?????

JFK is the worst airport and JetBlue is the worst airline

The food took two hours to be delivered to my seat, when I'm on an overnight flight I want to sleep asap after take off

Seats were great, the staff was great, and the food was about the best I've had on a plane, and is especially the best of any US-based carrier I've flown. Free Wi-Fi was also great.

Entertainment and wifi were very sub-par - audio issues and no wifi

Rude crew member. She seemed annoyed at me without me saying a single word. Also loudly admonished me for having my bag next to my seat instead of tucked away before landing. Just telling me to put it away and guiding me without giving me a lecture would have been enough.

Crew were fantastic and so catering and wonderful! Full score for the entire crew!

The amount of gate changes and delays is completely unacceptable. This has happened on 3 of 4 trips between Chicago and Dallas in 2026.

The flight was 3 hours and 40 minutes late. The communication around the delays was awful. I fly this route regularly and it is always late. I don't understand it. The flight attendants were not friendly and were generally loud. This was an overall bad look for American Airlines.

Very Good in general. Serving attitude are very good. Just a suggestion: There 2 things can be improved: 1. The flight attendants can lower the voices when they talked in the serving station. Sometimes they talked loud and we could hear clearly what they said about the passengers. 2. Please don’t throw the utensils and plates it’s too loud and noisy. They broke the glasses and plates sometimes at the business class. These all could be done in a gentle way. Just some small observations. Thanks.

The worst seat in any business class. Food are worst then economy class.

No food on 4.5 hour flight, wi-fi did not work. Terrible experience for a long haul flight.

We did not fly on American Airlines from Chicago to London. We were rebooked on British Airways (by American Airlines) and our luggage was left behind. A full day delay and lost luggage.

Business class flight attendant was very good. But our flight was delayed two hours for a “mechanical” bathroom issue that literally took 5 minutes to fix. Our plane landed early from its previous flight but still waited for a mechanic to show up to fix an obvious minor issue for almost three hours. This caused us to miss our connecting flight. They put us up in a Days Inn that was 17 miles away from the airport that took a half hour of driving just to get to and this was at 11pm at night. Then when we finally got back on a plane after a full day delay they left our luggage back in the airport. This was an international flight, so no luggage or belongings after flying 8 hours to a different country. We will NEVER fly American Airlines again.

The crew in the Vegas airport clearly was having a bad day … they moved on and the crew that checked us in for boarding was great, as was the flight crew. I did get the wheel of my carry on stuck in the overhead bin. Amazing team effort to include the flight attendants, the pilot, and another pilot who was on the flight as a passenger. Finally got it unstuck ✅

The economy seats are very cramped and the food was bizarre. However, I did like the greek yogurt option for breakfast.

horrible our connectig flight was late and we had to rush thru DFW to the next gate with 15 minutes time. Get to gate and its changed. no one knows whats going on . finally get a new gate and the plane has been sent back to the hanger . Boarded 4 hours after our original flight time and then sat at the gate for over an hour as the captian said the cargo doors were open and no one was in the airprot or on the ground to find out what was happening. this caused us to miss the first day of the tour as we missed our transfer and hotel meetup no apologies or accomodations offered to assist
