Don't take the 6am flight. Airport security and customs only open at 430am. So if you show up the recommended 3 hours before, you're waiting in line for nothing

I sat in the club. The seeds were fantastic. The meal was great and Entertainment was good. The crew was fantastic. I recommend it to everybody.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

Great flight and crew. Food isn't free and neither are headphones...

We were in economy class but paid for option Plus which offer you an extra snack after take off, free earplugs & blanket. The crew were very attentive. The comfort however wasn’t great, hard to be comfortable in such restraint place. Wasn’t able to sleep through out the 7hrs flight and was exhausted upon arrival.

The flights were on time and the crew was friendly and helpful. The food was ok. The seats were quite cramped and if the seat in front was tipped back there was very very little room. The entertainment was only on your own device and there was no usb charging

Boarding and staff were excellent. The food was ok. Very cramped seating. No existent entertainment other than on iPhone over wifi with poor choices of movie or shows. Bring your own entertainment. Nowhere to charge your phone

Delay was not properly communicated. Service, plane, value of ticker were all great.

Excellent service and food in the Club Class. Warmly recommend. Much better than AC.

My new suitcase got busted when I arrived at Toronto , two of the wheels are broken and can no longer be used , I am very disappointed over this situation but the flight and service was awesome .

From what I saw there was no entertainment. Similar to my flight to London, I personally would like the attendants to be more interactive during the flight.

Everything was great except food . It as okay not good not bad

better announcing at the gate prior to boarding and better organization of various gps

Flight attendant served beverage to everyone during meal service and forgot about me. Had to call her several times until she realized it. Not a good service for a business class flight

This time, I traveled in the economy, and it was surprisingly better than the eco-premium (food, comfort, and crew were noticeably worse in premium!)

Lots of water brought around by staff which is very important to stay hydrated on a long flight. There provided swiss chocolate icecream! The attention to detail is obvious. They really want to make their passengers entertained and comfortable.

This was an upgrade to business class and really enjoyed the experience. Much better than my earlier flight and thank you.

It was a pleasant experience accept temperature in the plane It was extremely cold in the airplane that I was shivering I got sick because of the extreme cold temperature on my flight

I never share this kind of things but I have to share this out of respect to myself and how surprised I was I got a shoulder injury so I went to Turkey to get a procedure to my shoulder ( I can prove and provide it with documentation from the hospital to you) and on my way in this flight, I asked one of the crew members who’ s name is j. Muller to help me to lift my carry on to put it up in to cabinet and she told me she can’t do it , and I said I m sorry I m injured , I really need help , then can you please find someone who can help me ? And she gave me this nasty attitude and refused to help me . Then I was shocked because all I asked was for help, i didn’t even ask her to put my carry on bag up for me , all I asked her to help me so we can do it together. Then 5 minutes later another crew member who’s name is Jenny Rutz came and asked me if everything is ok And i explained her what happened and she told me if I create more problem, she will not let me fly i was shocked, all I told her was I was injured and I needed some help to put my luggage up . I am extremely shocked and upset , this was so unprofessional, rude and unnecessary. I thought their job is to help us in our flight. She disrespected me , embarrassed me, made me feel like I m a problem and threatened me to get me out of the plane In front of everyone I am 41 years old mature and kind woman, i have never in my life experienced something this unprofessional and this disrespectful ever They both turned something so simple and normal into this terrible experience for me and for the people sitting around me . So it was so uncomfortable and unfair that the other passengers who were sitting around me and next to me got negatively affected by the event and told me to take their phone number so that they can be my witness for the crew member’ rudeness and unprofessionalism I m still very upset how can people be this rude and heartless I will never ever want to fly with your airline company again

Crew was wonderful, snacks were so good and quite a variety for free, food was mediocre, big selection of movies and they kept lavatories pretty clean throughout the flight

It was unclear that additional passport control was needed before boarding. The seats were cramped and uncomfortable even for small persons. The arm rests were unable to be lifted completely out of the way and the media controls cut-out made them uncomfortable to lean on. One audio channel was not working on one of our seats.

They canceled our flight and left us stranded to figure it out

We appreciated the friendly, efficient, and professional flight attendants. A wider selection of hot foods would be nice.

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

Did not have enough time from Venice seaport at Ravenna to get to Venice airport in order to make the scheduled flights. Need to have at least 3+ hours from ship docking to airport.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

The plane used to go to Chicago was a bit outdated and needed a refresh

My connecting gate in .Chicago was across the aisle from my arriving gate. Otherwise I would not have made my connection. So that was very fortunate.

The TSA people or whatever you call them were a bit rude- I asked why I had to take my shoes off bc I'm 75 and in the USA, I don't have to. The man didn't need to snap at me. It wasn't even busy! The plane was ok, a bit small for such a long flight, but I'm very familiar with the 737 used ( I fly it often between SFO and SAN) service was ok-nothing special. If I drank alcohol I guess I would be happy with free choices. the plane was HOT and even the FA commented on it. They tried to get it cooler, but it never happened.

I have flown on many airlines all over the world, and this plane flight was the most uncomfortable I have ever experienced.

Flight from Minneapolis to Montreal was easy, breezy. Small plane, so not much overhead space. The seats felt slightly smaller than normal, but not uncomfortable for my body type. No screens in the seats for watching movies or shows, but I don't mind, I'm more of a reader.

Excellent overall experience. Seats were comfortable and ample leg room.

Con: Travelers shouldn't have to pay a fee for first checked bag, in any fare class. Pro: Plane was new and comfortable, even for the seats that didn't cost extra.

Wheelchair help is not reliable & chaotic. No food and minimal liquids for a flight at 6;25.

I wasnt able to choose my seat during booking my flight _months_ in advance and then when I checked in for my flight, I _still_ couldnt choose my seat. I was finally able to get a seat when I got to the gate, and they stuck me in a middle seat next to a jerk. This was my return flight, and on my departing flight I was able to choose my seat, so I dont understand what the issue was but it was very annoying and a miserable ~6.5 hours on the return flight.

Gate changed twice, boarding late. However, there was more than usual leg room. Crew was fine. No entertainment due to computer problem.

I don’t think the on-board testing worked on any of the 4 Air Canada flights for this trip. And in this particular flight, the entertainment and WiFi was out for a portion of the journey.

Ok, a very small soda in a small glass was all that was served. Pitiful. Comfort seat was not, no legroom at all would not recommend comfort class, not worth the extra.

Delayed take off but I think they waited for passengers.

The flight crew did a good job, the main problem I had was in the layout of the pod itself. I know it does not matter but the connection for the head phones was not A- easy to find, B- very difficult to do based on the placement ( behind the right shoulder, very hard to reach, the type of plug on the frame vs the actual plug of the headphones), C due to the location and the way it connected, it did not allow me to use my own headphones, D- very low quality and very uncomfortable headphones, E- Surprisingly, very old selections of movies, for me, at least. I will still fly with Lufthansa as you deliver a very good product overall and I enjoy the quality of service, the ease and the prices. Thank you.

I had to fly United where the flight crew was atrocious

Flight was delayed for no reason and I missed my connection. This added another day of travel and I missed an event I was traveling home for.

I traveled with my sister, however ,we booked a flight separately, and we don't sitting next to each other. The staff on the board where on the top of this unit they find us sitting together. Ty lufthansa team. U are the best

Courtesy of waitress. Could improve on time management and check-in

Other than the delay of flight, this crew tried to make the best of bad situation.

Terrible. Super uncomfortable/less room than a domestic flight and flight was 9.5 hours. Food was terrible. Flight attendants slammed the cart into 2 people in our party numerous times as they were both over 6' tall and sitting in the aisle.

The wi-fi wasn’t working on the flight from Munich to Chicago and I’d already paid for two devices before they notified us not to purchase it. I think that should have been mentioned as we checked in or boarded not once we were already on board during the safety brief. The flight attendant stated that we’d get a voucher, but we didn’t receive anything while on the flight, so I don’t know who’s responsible for issuing a voucher or refund.

The airplane did not offer standard outlets so I was unable to work on my laptop. This is totally unacceptable for an international flight.
