Be prepared for unintentional mistakes and rudeness due to the language barrier. If you’re on the taller, broader side, there will be 13 hours of discomfort with smaller seating and very tight bathrooms. The food is unsatisfactory so bring supplements.

“Comfort economy” is worth it. Noise cancelling headphones/earbuds are important, along with an eye mask.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.

How can you rate a flight when it is canceled after you leave the gate & 3 hours into sitting there or in remote area of airport after mechanical problems

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

Late plane. Only one crew on the ground so we b had to wait for Denver flight to come in, board, and depart. At 78 yrs of age I was not pleased trying to get my connection. What really made me angry was the notification you sent me to hurry up or I would miss my connection. Why tell me to hurry up when you got me in late. It was not a good way of treating customers.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

Seats were not super comfortable and food was not good at all. If I had a chance I would definitely fly a different airline. Of course they are better than any budget airline, but not by much.

Flew steerage class. Short on leg room unless you pay more. No window unless you pay more. Etc. United is trying to squeeze every cent from you. It doesn’t make for any loyalty.

I should have been credited for my flight. A day after booking I tried to cancel and the service is horrible. I will never use your service or Norse again. I will make sure to tell everyone I know about the experience.

Flight was canceled in July-nearly six months prior to departure and cost of alternative was double, but only cost was reimbursed.

Departure time from Rome and arrival time at JFK resulted in very short waits at security and customs. Dropping bags at ticket counter was completed quickly. Boarding was delayed by some sort of terminal equipment problem halfway through the process. No announcement or information was given to the large group standing waiting to board. Basic seat was comfortable ( paid for an aisle seat ) Didn’t purchase food. Given the price (purchased one way ticket day before flight) I was impressed with the Norse experience

Seats were comfortable, staff was friendly. Great value for the price.

The seats are nice in premium economy. The service was fine. No wifi on board and the entertainment selection wasn't the greatest. It was good for a budget friendly airline.

The overpriced dinner was pasta, bread and an awfully sweet dessert…. a feast of inexpensive carbs. She was the exception, but one flight attendant was incredibly rude. Cheap ticket though.

Terminal experiences, including departure and deplaning were the weak points of our trip. Appreciated that premium passengers boarded and deplaned in group 1, but experience with buses did not feel premium. Terminals used at CDG and JFK had old, limited facilities and no good lounges. In flight experience was good and crew worked hard.

It was very uncomfortable. I would never book any flights with Norse anymore .

The flight attendants were extremely rude. I hate the culture of Norse air. Their is nothing really economical about it, the flights are slightly less expensive than average but it doesn’t justify no food, no blankets or pillows - my god you have to pay extra just to make your already over crowded no leg room flight just comfortable enough to be enjoyable. As if travel isn’t hard enough already. You have to pay extra to pick a seat so if you really are on a tight budget you’ll be left with the most uncomfortable, saddest flight of your life while the flight attendants treats you like the steerage on the HMS Titanic.

"I felt uncomfortable. It's well known that Norway is a racist country. As soon as they detected my accent, they were very rude."

It was ok. Overall comfortable but Seat back could not be adjusted and food options were limited.

The price for Premium Economy seats very competitive and ITA beat the big guys in terms of fair. However, seat comfort was below expectations. Movie selection was poor. Food - absolutely horrible!! I felt like a prisoner for 13 hours being fed cold damp rolls and room temp water. NOT what I expected for Premium Economy!!

Most importantly, got us there and back safely and on time. Seats in Prem Econ spacious enough and comfortable. But pulldown footrest on both flights inadequate/broken. Crew...mixed: a few were quite pleasant, others seemed disinterested. Food was underwhelming. Yes, I know it's just "airplane food", so dont expect much... but even United is doing better now, and BA more so. Would I fly ITA again...perhaps. Price diff was main selector this time, almost 1K LESS/person than UA. I'm naturally frugal -- For 2K I'll put up with some small inconveniences.

ITA changed our 9 hr direct flight without giving any reason to 4 stop overs 24 hrs flight without delays.

Poor food choices for AVML. Totally out of the world food. Bad food menu.

Flight attendant really had bad behavior.. yelled at people when she is trying to defend, to have favor w her people..!

Appreciated being met with a glass of sparkling wine - also the warm cleansing towel offered before the meal. The food was tasty!

Inside plane needs to be updated, the lady sitting behind me was saying the frame from the window fell on her lap right before taking off and seats are very uncomfortable, cushioning is need of repair ASAP.

Overbooked. They left a lot of passengers on the ground

Need better food options. Need warm food both times Stevie was provided. Bathrooms are too small. For an international flights, seats are small and leg room isn’t enough. And for an international flight, serving spirits should be included, not just Italian beer and cheap wine. All the tv/film entertainment is quite old and not updated, but the size of the screen was good.

Los Angeles to London. 25th of April 2026. Business class. I was flying backwards with a complete stranger snoring next to me. In Business class. Males and females, strangers lying next to each other. Seats were backwards. I paid for comfort. I got dizziness and stress.

Significant delays on the return blamed on weather. Otherwise pleasant and helpful staff. Overcooked chicken on return limited options for dinner.

The crew was exceptionally good. Came around with snacks and drinks multiple times during the flight. I asked for hot water and they remembered. Responded to call light promptly. Very pleasant. The aircraft was also kept very clean. Boarding was organized. Overall was a great experience.

I was downgraded from business class to economy class with no compensation. American Airlines is absolutely the worst airline for international travel. They treat their business class customers like dogs.

British Airays fails to enforce its own guidelines regarding carry on size limits. There were MANY passengers with full suitcases stuffing them into the overhead compartments leaving no space for others, like me, who adhere to the posted sizes. I had to put my carryone bag into my foot space, in additon to my carryon personal item, leaving me cramped for a seven hour flight. I was in physical pain, and I attribute this entirely to staff unwilling to enforce limits. The infotainment system was horrible. the touchscreens did dot work correctly, and there was no information on system operation. I am 77 years old, and a lifelong movie-goer. I recognized ONE movie (and not much better TV shows). It seems that BA saves royalty money by limiting its move and TV selection to absolute rubbish. The FlightAware program is the worst informationsystm I have ever seen, it is completely worthless. I pay attention to the safety briefings...in the event of an emergency, one is supposed to assume the "brace" position, except the seats are so close together, front to back, that it is not possible to assume the position without striking the seat in front of you. at age 77, and a lifelong traveler, this is the worst flight experience I have ever had, and I will never fly British Airways again

The crew has always been great on BA. They are very friendly and accommodating. I like that they have vegetarian options already in the menu. And the free wine is a nice perk.) I noticed (both directions of my trip) minor upgrades/ replacements needed on the plane itself (touch screen didn't work with touch; bathroom light didn't go on). However, this is one of my favorite airlines.

There was a delay for the San Francisco-London flight, but we were all informed via text and email. The staff was very friendly and nice and the food was good. I do recommend that the airline offer something without eggs or something vegan for the vegetarian meal option. A lot of Indians are lacto-vegetarian, while some could be allergic to eggs/dairy.

Crew were nice, food was good. Boarding was horrendous. We were driven around the airport in a bus forced to climb a long flight of very steep stairs with no adequate handrails to board the plane . In many many years of flying to the US I have never been required to do this . There was no assistance for those needing help getting up the stairs to the plane. A fellow passenger helped me. No idea how other elderly, physically limited passengers or those with young children managed . It was a full flight with crowds trying to get up the stairs. It was an accident waiting to happen.

Horrible, the plane is just old and junky...Filthy restroom, seat was as hard as rock. The food, mystery side dish, inedible..geez..just Horrible. Never flying BA again

the service on Business class should be improved to be at par with industry leaders like Cathay Pacific and Singapore AIrlines. A lot of room for improvement.

Crew was very responsive to give soft drinks etc.. At Frankfurt Airport Special Assistance did a great job for us. The seat cushions were simply bad and not up to the mark for Premium Economy which we chose. All the cushions from Business to Economy were poor. Also, any snack besides lunch and breakfast, you have to purchase including chips and chocolate. It is simply cheap. I don't think I will fly Condor anytime soon

The short leg flight was fine. Crew and airport were nice to allow special assistance which helped.

Planes are new and clean and staff is attentive. Food wasn't great and chair cushions were very uncomfortable for long haul flights.

The boarding process is a nightmare. They put you on a bus for 30 minutes with no air flow. The process was extremely slow and we were behind schedule so they auto rebooked us on a flight for our layover. The new flight was 4 hours later in the day, we landed an hour and 45 minutes before our layover flight so this was completely unnecessary. When I called to get us back on the original flight the support staff was useless

It’s a budget-friendly airline, so expect smaller meal and snack portions and no free alcohol to drink on international flights. Airline food is never exciting in economy class, so I always plan on taking my own food and snacks- and I don’t consume alcohol, so no complaints from me! Flight attendants were friendly, attentive, and helpful. The airplane was newer with USB a+c charging ports, massive infotainment screens, and a lot of entertainment media to choose from. The airplane seats are less padded than other airlines I’ve been to, but the benefit is that there was more legroom because of the thinner seat profiles. Honestly, more legroom gave me more comfort than having more padding on a seat (which just gets flattened over time and repeated use) Overall, I really liked my Condor experiences (4 different planes) from LAX-Frankfurt-Barcelona and back. I would not hesitate to fly with them in the future, if the prices are lower than other companies

They made us walk thru entire Frankfurt Airport, which at this age. With very less time, we had to run. It was unacceptable.

They answer the phone promptly. Crew is friendly and they work efficiently.

I flew premium economy. My only complaint is the size of the bathroom. I am 6’2 I. Tried to rush my teeth in there and ended up getting toothpaste and water in my pants. And the only way to do it was by sitting on the toilet

My flight was delayed twice. It finally left 24 hours later. In addition there were conflicting messages between kayak and condor that made the experience worse.

Upgraded to premium economy at the gate. Well worth it!
