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.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Service was professional and quick. Premium economy seat was comfortable given the class

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Crew was great! Good meals. Had room to stretch out

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

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.

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

Small plane. Tight seating . What can one say except that it was fast!

My only complaint is that during my 8-hour-long flight, the flight attendants came around with the coffee and tea cart twice instead of the alcoholic beverage cart. I would rather sleep on a plane than rush to the bathroom to take a dump. I asked the flight attendant if I could have a beer instead of coffee or tea. Unfortunately, she said the bar is closed. That tells me that she was too lazy to get me a beer on the plane. I was not happy about that.

Other than Air Lingus not loading one piece of luggage on our flight from Dublin to Barcelona, with it arriving one day after we arrived in Barcelona, all was good.

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

OK overall. Flight was delayed Crew on flight was good

On time, only a little turbulence, very competent and caring attendants. Clear information.

Late late late. Delayed and arrived an hour late for a 1 hour 45 minute connection. Every time. Poor record for this company. I try to fly any other carrier first.

The flights are literally always delayed arriving, boarding and taking off so they are always late for the connection. I planned ahead so I was okay but many others aren't. The food was terrible. The staff was very pleasant. I appreciate boarding back to front.

Just a small inconvenience was the fact that not all bathrooms were functional.

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.

Crazy and confusing check in process for connecting international flights. Extremely uncomfortable seats in economy, bad in flight service with useless attendants, 10 year old movie selection, inedible food + only 1 full meal for 12+ hours long flight - 2nd snack was a cold bun with 1 slice of tomato and 1 slice of cucumber; 3rd was 2 breads - 1 hot and 1 cold. Finally absolute bad information on arrival time - in flight suggested we will reach at 12 AM until last minute, when we landed it was 1:15 PM

The crew was business like and not very friendly. It was very disappointing in that they handed out the meal at the beginning of our journey. Eight hours later, they handed a sandwich and a drink. During their eight hour break all they did was sit in the back, looked at their phone and read. They never came down the aisle during those eight hours and offered another beverage or to See if there was anything they could do for the passengers.

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.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

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
