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.

Premium economy is like the forgotten class. Aside from meal service never saw a flight attendant. Any additional beverages required going to the very back of the plane to request and there was rarely an attendant there. Seat leg / foot rest hardly elevates and not well suite for someone under 5’6. Bulky armrests

Delta One upgrade it would have been great if my tray extended (it was jammed and wouldn’t pull out), seatbelt had too much slack & my little cabin door didn’t close properly

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

Seats comfortable, service and food very mediocre, staff not very attentive, worse than many other our flights with Delta.

Crew blocked exits to front of ship with galley carts. Also split five person family apart on international flight without fixing.

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

The crew took good care of us. The flight from ATL to SFO is a longer one, and there were multiple beverage offerings. I like the 757's that Delta uses. Good airplane that is comfortable. I do wish Delta would separate Priority boarding from the better seats. I would gladly take a smaller seat in an open row than be jammed into Comfort just to get priority boarding, just to make sure I don't have to check a bag.

The crew was not very visible. This might be a good thing for people who wanted to sleep but seemed odd when compared to the Atlantic crossing where they are more present in the cabin. The Food (beef) was not good. Tough and tasteless. Would love to see more choices on a long flight like that.

Gate agent rushed to fill hot jetway with crowd so it took over 12 minutes to go from gate to plane. Just like a discount airline Pooly prepared cabin and third time that claim of rough air prevented any cabin service. Friends on a Southwest flight at similar time had service.

On the way my flight entertainment wouldn’t work the screen went black and no matter how many times I tried to turn it on it wouldn’t. Food was surprisingly good but the tray tables were tiny so you couldn’t get anything else on the table. The seats hardly go back and are not overly comfortable. Wouldn’t fly United again.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Flight was late - I was downgraded from first class to coach

Movie selection is good. Crew did not understand mileage program and were no help. Sick later. Food?

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

The flight attendants were very rude, beyond comprehension. I took a business class from London to SFO for the first time on United. When I asked for a second piece of bread during dinner, the serving attendant threw a 3rd bread on my plate and said, “here. You can have this one too”! I couldn’t believe the rudeness of the attendant. Most all attendants were very rude, unhelpful, sing the food was absolutely disgusting. Never fly United internationally in business class. My flight back to SFO was a nightmare!!

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

7 hours delayed due to operational issues on United’s end. Basically laziness.

Flight from Rome to SFO was excellent compared To our flight to Europe from SFO. The food was much tastier. You can see how UNITED is skimping, though. Instead of getting something mid flight you had to ask for it. It was not automatically served. There was a cookie at the end of the arrival meal, for example that tasted like it just came out of a box. They used to serve a little container of nuts, now … a tiny container of nuts, mixed with pretzels. This was business class that you really have to pay for! But this is minor complaints compared to the overall. My major complaint is the position of the even numbered seats by the windows. You have to turn around to see your window & the positioning as some other controls are harder to get at. This is compared to the odd number seat that are perfectly aligned.

The food quality sucks. One must starve if they do not eat flesh Or wheat based products Some variety would be expected. The trivial amount of snacks and or food is inhumane

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."

Norse is one of those airlines that sells the luggage and the good seats if you want them but otherwise the prices are great. It was very comfortable, the crew was great, and the food was actually good. I will take it again.

Everything was good during the flight. But it's the only flight that I have experienced where food is not included not even drinks or even water unless you pay for it. For such a long trip to not offer even a glass of water I think it's very extreme!

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.

my flight from Rome to Boston was on a very old plane. My video and audio did not work.

Awful cold sandwich, pizza was bad and coffee was extremely cold I expected better quality in wines on the way to Rome I order red wine and could not drink it ! Bad quality of wine . Being an European airline’s wine are inexpensive so could have better selección of wines . So on the way back a settle for water with is a pity . The crew disappear and didn’t pick up the trays after meals or the garbage of the snacks . Iberia has better service and other airlines

The toilets are very small for a long trip like this. There is no space whatsoever. Totally unusable,

This airplane is much better. Not worn out like the one we flew with fr NY to Rome. Flight attendants were ok.

Poor. The airlines left my luggage in Miami. It took 2 1/2 days to get my luggage at my destination. I was forced to buy clothes and daily items for days. There was little concern to get my bag to me which highly impacted my trip. Seats were cramped as well. Would not recommend this airline to anyone.

This was our return flight. It was slightly better than the one we took to go to Rome, mainly because the food was slightly better and more abondant. On our LA-Fco flight the food was way below average. Also, it felt like the legroom in Economy was smaller than other airlines we used in the past - my knees were touching the seat in front of me.

There was so little leg space in middle seat that the blanket/pillow accessories and my feet could not fit. Knees were 1 inch from seat in front and when person in front reclined, it was uncomfortably invasive in my space. I am not large, 5’5” and 130 pounds

Wonderful! Everyone very helpful and kind. Returning flight was cancelled but rebooking was easy.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Entertainment devices on A380 need to be fixed, the seats might do with updates.

Everything. Employees offered to help me because I had to use a cane.

Check-in and boarding were great. On flight staff were rude and disrespectful. Paid for extra room and found it incredibly cramped. Bathrooms kept in poor condition. Overall negative experience.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

Audi visual not working for a whole group of seats in first class. How does a plane leave the main hub in such poor condition? How much that we can’t see so immediately is also compromised?

main meals are horrible but then you dont fly for the food

The to flight was excellent but the return flight the seats seemed not cushioning enough.

Great flight. One unique individual assisting in business class who should have not been there. Need more generic meals, not British centric.

Crew service was poor and very little difference between premium economy and economy. Disappointed.
