Checking in and crew were great. Seats in front of you in economy recline so much that you can't get out of your seat. I guess thats why its economy....

Flight was on time. Could have been a little more comfortable. Baby cried all night.

The chicken on the flight Boston to Zurich wasn’t very good. It was bland passable. Too much sugar in the Cole slaw. Cabbage is an amazing veg and can be much more crisp and alive. Flight attendants were Wonderful! Seats were a bit beat up but okay. In economy it was tight when the person in front learned back the screen became too close.

On time and my bag made it. My parents on British Air had their bag held/lost at LHR, so Swiss definitely won that contest.

Wonderful, i asked at front gate to change my seat up closer and they gave me a row with no one in it. Very kind of them as the flight was on the light side.

Horrible!! The WiFi was not working, the food was awful

The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

Excellent Airline. Food, crew and comfort was perfect. Entertainment screens were old. Didn’t like them.

Flight was very full and we had to checkin our carry on. Stuff however promised us that our luggage will be the first one to come out and it did

Crew members were good. Seats were packed and too tight .

Friendly flight attendants and reasonable good food. Quick service throughout the trip.

Flight crew was very kind and polite. They had to deal with an unnamed issue right beside me, and did so with respect.

The crew were nice and courteous. Exonomy seats were worse than expected. Overhead bin space was non existent thanks to loose enforcement of the carryon size and letting passengers put up their purses jackets and backpacks up there leaving no space for others with a small conforming carry on. Food was not good at all. Perhaps worse chicken I ever had in my life. I had to have them take it after tasting how bad it was. Whoever made that should not be in food making business.

The crew was amazing. Our seats was not very clean and even that was not a full flight but our seats was right beside the WC which did not let us to have a moment of rest.

Mediocre. Maybe due to Economy light. Staff was great. Space shrunk, not for me, and definitely not for Vikings. Food was decent. Assistance lagging. There was a possibility to upgrade to Premium economy, however my bid was immediately classified as low and not even considered (though well over minimum bid). Thus I was no bleeding dry.

Basic flight. Great for something under two hours. Seats were a bit dated and uncomfortable

The stewardess was incredibly rude. The gave you only one drink with dinner.

Excellent crew members, but my seat and food wasn’t the best

Crew was unresponsive to request for a soda. Food was horrible and I’d venture to guess many others thought so as well by the amount that they trashed. Made me sick to my stomach and ended up in bed the remainder of the day once we arrived. Screaming child for 3/4 of the almost 8 hour flight. Crew had no headphones whatsoever for free or purchase. Seating way too tight and we upgraded our seats. I do not see us ever flying this airline again.

Boarding and crew were excellent. Seat could have been more comfortable (hard on lower back).

The flight from Frankfurt to Pisa was cancelled and we were rebooked to route through London. The flight to London was delayed for maintenance issues and we missed our connection flight. Lufthansa automatically rebooked my wife on the next flight but I was not rebooked. I spent over an hour trying to get onto the flight. Ultimately my wife’s gate checked bag from Washington did not arrive in Pisa and remained in London. Very bad experience overall.

This was a small aircraft (relatively) and we were delayed half an hour on takeoff, which is not the airlines fault.

Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.

The very best airline service I have experienced. Better than domestic airlines first class and I flew Economy Plus!

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

Boarding was 2 hours late and then we were delayed another 5 hours on the tarmac. I'm sure the crew were also tired, but some of them were rather snappy. The special dinner I ordered was not served, and they only served a tapas box on takeoff and breakfast before landing. That was disappointing in premium economy. However United was good at rebooking my connecting flight.

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

The crew was great. The food was typical, but decent. Everything else - mediocre to poor. The flight was late arriving - happily for us and our 49 minute connection (what idiot came up with that?)- in another concourse - that concourse changed before we arrived (ticket and app was showing the incorrect gate - when we boarded at the correct gate - known by the airport person pushing my assistance cart). Had I walked and read the screens or United app I would have missed the flight! May other people arrived late to the correct gate, having been victims of a last minute gate change, were also relieved the flight arrived late. The aircraft (Boeing 757) was a sardine-can due to an uncomfortable seat pitch distance. The material or seat was beyond not comfortable, but I'm sure they made a lot of money with that aircraft type. I spent a lot of time standing in the back (in the middle of the night/morning to rest my back). I learned my lesson - any trans-oceanic fight - avoid United or American Airlines - and look for Airbus or Boeing 737, 767, 777. Also, pay for business class or premium coach seating.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

A little more friendliness from that crew of the day.

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.

Flight crew was superb. Meal was one of the meals at altitude I’ve had

Couldn’t check In online, message was couldn’t check in until Sunday morning though plane left Saturday night. Checked in okay at airport but caused slot if stress.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Lufthansa was great. Crew on board excellent. Frankfort passport control horrible it took about two hours to get through. After waiting in line for hours there was a discussion with the passenger in front of me that was taking forever. The couple behind me had a connecting flight to Turkey in 30 minutes and asked border control officer of her situation and the control officer told the couple in a nasty tone if you don’t like it you can go to another line which would have surely made her miss the flight. Border patrol officers were not helpful. Finally made it through I had to exit and reentry for security check for my connecting flight which Lufthansa changed gates and I had to run to get to A60. Which it seemed 2 kilometers to get to but I made it. If i fid not have 2.5 hrs layover i would have missed my connecting flight to Milan. Not sure if I will fly through Frankfort in the future.

When our flight was canceled and rebooked, my husband's meal request was not transfered. As a result, there was nothing he could eat for dinner and breakfast on the new flight, save a side salad and roll.

Very efficient and excellent service. Nice amenities and beautiful plane. Elevated meals. Boarding could have been more organized. We missed our connecting flight due to EU entry but Lufthansa was extremely quick to rebook us.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

good entertainment package but rather small seats for business class

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets
