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.

I usually get upgraded so my experience is usually amazing. I did not get upgraded this time - which was fine - but the wifi had issues, the monitors were going in & out, & (though not Delta's fault) one of the gentlemen next to me desperately needed a shower.

I usually get upgraded so my experience is usually amazing. I did not get upgraded this time - which was fine - but the wifi had issues, the monitors were going in & out, & (though not Delta's fault) one of the gentlemen next to me desperately needed a shower.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

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.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Flight arrived 30 min early and bag was waiting at the baggage pickup. United Club HNL was one of the nicest in the system

Mean flight attendant. I wanted to reuse my plastic cup, but he (Matthew) said he can't for safety. I then said "I don't want water then" and he poured me a glass. I hope Matthew gets herpes and spends the rest of his life poor, lonely, and homeless.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Both flights delayed. 2nd flight over 3 hours late mechanical issues

Flight was delayed 45 minutes because originating flight was coming from Newark. No complimentary snacks were offered on this 5+ hour flight. No screens for the flight, but movies offered if you had already downloaded the United app (which I hadn't on my ipad). No USB ports, only a flimsy plug-in port near the bottom of the seat that was hard to see and kept coming unplugged.

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

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 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."

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.

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.

This review if for American Airlines. From London to LA, British Airways customers flew American Airlines and there was a small incident on the plane with a customer that was sitting next to me. She had a gluten free meal which she selected online. The flight attendant brought her food and both times, it contained gluten (bread, cracker) and by the second time, the customer mentioned about the issue to the flight attendant because she is highly allergic to gluten. Customer was very gentle and just wanted to note that both her meals contained gluten on the tray. The whole situation could have ended really well if flight attendant just apologized and mentioned she would relay the message to the responsible party. Instead, she entered defensive mode and started making some BS excuse about how the cracker that was supposed to be mine, fell onto her tray instead. Mind me, I already had that cracker on my tray. I doubt I would be given two. Also, she mentioned that the bread from the previous meal was gluten free. REALLY? I ate that bread and it tasted like it had PLENTY of gluten. The whole situation was handled so poorly, not only by that one flight attendant, but by 2 others. The reason I intervened is because the customer sitting next to me was tearing and all she did was mention the mistake which could have cause her health great damage, and instead she received attacks and excuses. AA, you should train your employees how to better handle situations like this. A 'well, I don't see why this problem is a big deal since you (the customer with allergies) read the ingredients and avoided eating the cracker that "accidentally fell" from the tray of the customer sitting next to you,' should not have been coming out of a flight attendant's mouth.

I was unable to board the flight because I was unable to acquire a visa , Brexit changed my ability to get an ETA, I’m a Trinidad citizen and it takes weeks to get a visa

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

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

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.

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.
