Excellent comfort, service, boarding, deplaning. Bad meal (preselected vegetarian) but only vegan was available from a passenger cancellation. Bland and not very filling except for thin passengers.

Excellent comfort, service, boarding, deplaning. Bad meal (preselected vegetarian) but only vegan was available from a passenger cancellation. Bland and not very filling except for thin passengers.

Some of the rudest flight crew I have encountered in over 40 years of flying. Despite pre-ordering a vegetarian meal, the only options provided included meat, with no other choices or substitutes offered. Additionally, the sound on the entertainment system was not working. With flight delays had only 20 minutes to make it to next boarding gate and after running most of the way made it to flight with 2 minutes to spare Will never fly SAS again and I am looking for partial refund for false advertisement.

My biggest recurring disappointment is that I buy a pre-assihned seat while pucrhasing the ticket and then when checking in it disappeared and I have to buy it again. That's very disappointing and actually a reason I will actively avoid SAS in the future

Payed $140 xtra for seat arrangement Did not get the preselected seats neiter outbound nor inbound. Absolutely not worth the xtra money

not good missed my connection SAS did not leave me anywhere near enough time to make my connection. Ended up adding about 10 hours to my travel day

Overall a great experience. I didn’t like that they didn’t assign seats until we arrived at airport. All the employees we interacted with at the airport and on the flight were kind and helpful.

Cut out the nickel and dime pricing for "seat selection" and baggage, To do this on an international flight is just mind boggling. Seriously, why treat customers this way??? Nobody wants these hidden extra fees and everybody hates them. Also plane was too warm and no air vent, and water dripped from the ceiling at one point,

Maybe more diverse entertainment. Although the inflight cameras were amazing 10/10

I upgraded to economy plus and it’s so worth the price. The crew is exceptional and the food is pretty decent. I would definitely fly with them again.

I paid for wifi and it worked about a total of 5 min. Feel ripped off

I like to do online-check-ins. With this flight it was not possible because it reported (data entry error). I double checked everything and changed how my name is represented, but I could never get passed the error. The customer service could not help me. Had to leave earlier to the airport. A long line of people were waiting to check in. There were only 3 check-in counters for more than 100 people waiting. Instead of opening more, they closed one of the counters. I got assigned a seat almost all the way in the back in the middle. A lady at the gate was able to assign a seat with more leg room at an isle. I liked the offer of snacks and drinks during the flight. A nice touch.

This leg of the trip was ok, though the check in agent could have given us assigned seats. I have a feeling though that agent could not as it became clear later on. Please see below. However, the leg from Zurich to San Francisco was horrendous. We only had less than 1.5 hours to transfer to a different gate using transfer train. We asked at the business lounge and were told to see the gate agent. When we went there there was a long line. As we approached business class desk, we were yelled at and the agent said "I will not talk to you". After a long wait, we were then told our seats will be assigned at the boarding time!!! After a time, the agent announced for volunteers as the business class was overbooked. We did get seats in the end but were separated at which point, we just decided it was not worth trying to ask for seats. I am not sure I will ever use Arrant Grant. I understand the Arrant Grant need to charge commission. However, what Lufthansa charged $10315.80 Canadian dollars ($7316.17 US dollars) was so much less than $12670.80 Arrant Grant charged me. I think commission of $5354,53 US dollars is too excessive. Also, I tried to upgrade to First Class and was told that we had upgraded once already and couldn't upgrade again. So, a terrible experience.

Boarding was very slow and unorganized. As a result we were delayed for 25 minutes crew is not friendly. food , entertainment and service was mediocre I bought in flight internet and paid $42.61 it did not eben worked after 10 minutes and no one helped I would like a refund on that please

The transfer was awful, everyone was running to catch the flight, there was no information on the process. We git to the gate and the boarding was late and had to stay in different lines but there was no guidance. The flight was late and uncomfortable, probably one of the worst flights I have been on. The luggage was sent to a different terminal and still did not make back to us.

The awful part was the customs delays at ZRH. The good part is the flight was delayed long enough to accommodate. The flight itself was fairly comfortable.

Great flight. I didn't watch the entertainment. I used my iPad the whole flight. But, staff was great, smooth flight, comfortable seat (business seat 7A) and food was really good (I'm a vegetarian).

Even though I paid extra for more room, we were very cramped and the seats were hard. Also, when we checked in they did not post the gate we were to arrive at even though we were half an hour away from boarding. The agent did not know either. Actually, the flight from Porto to Zurich did to have the gate posted, and there were very few agents in the boarding areas who could help us. I would never fly Swiss Air again.

horrible.. they cause such a problem and my daughter 14 years old was stranded in san francisco

All the flight to USA were arranged to E terminal whereas from Dubrovnik arriving on Zurich is on A80, have to walk all the way from A to E, even need transfer bus , for short transfer time like in an hour, we have to work fast, as soon as arrived at E, it is about time to boarding, pretty tight schedule, I hope Zurich airport can make some rearrangement so that transfer people do not have to walk long way. For short transfer time people, such as 50 min, this is even impossible if still like this.

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.

Starlink internet made the flight time shrink and I was able to work.

The plane was so old. I paid a ridiculous amount to fly business and there was no internet for six hours! This can't be happening in 2026 and especially in cross country flights where there are a high volume of business travelers.

The food could have been better and the entertainment could have better movies or streaming.

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

The food could be much better. Also very unfortunate that most of business class seats were empty but I could not upgrade.

Bag got checked but I thought one personal item was guaranteed.

The seats are very small, that is all the staff did a good job.

The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience

First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.

United did nit provide any updated on flight crew not bein available until boarding time started. It was bad. Itws alate night flight and there no proactive communication and iha d an important meeting that i missed due to thus

After flying on Icelandair to England and getting a greeting glass of champagne, free drinks and salmon I returned to the US on United for around the same price and got told immediately that I would have to eat a vegetarian meal because everything else was gone and every time I paused thinking in flight entertainment I got advertisements on the screen. On the Icelandair flight I had a great selection of documentary films and on United I was reduced to watching the Spider-Man movie. Guest which airline I look forward to flying again?

The flight from FRA to SFO was uncomfortable. The crew allowed people to change seats after boarding finished, but then made some people move back to their seats but not others, which resulted in my wife and I having to sit in two middle seats for an 11 hour flight. The entertainment system was not working well throughout the flight, and stopped working completely around hour 8.

Inflight food quality is definitely declining. Only one hot food was served and rest of were boxed meals. That’s not how was done before. Better to fly Asia or Qatar carriers for better service.

The seats on Lufthansa’s international business class on the A350-900 is the worst product in the market. Our chief purser was AMAZING though. She is the best FA I have had in many years.

I have very bad experience with United because Vince two weeks that I did not receive my luggage yet

Generally good. Not their fault but the design of the Boeing 747 had seating supports directly in line with my legs. So my legs always had to straddle this support which caused body misallignment. Such poor design from Boeing. There was no USB port for me to charge my phone. The screen touch control was very poor.

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

Never happened. Flight was delayed. Had to be re rojyed

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

I was very happy with everything, thank you for the smooth flight ✈️

Terrible we had to wait out in the cold for transfer bus to take us to the plane. Once we finally got on the plane seat had no cushioning not comfortable at all. Food was overcooked and dried out. I was skipped over when they served drinks I had to call them back to give me a drink with my food. Overall terrible experience this time. I have used BA before and never experienced service like this before. If this keeps up I will look for other options

My experience on this flight was good. The seat I had had a lot of leg room, but it was so close to the aisle that the flight attendants kept bumping into my visual monitor connected to my seat to watch tv.

We never made this flight due to the flight from Barcelona being delayed, which I have reviewed in a separate review. But I can tell you that the Delta Airlines flight that did get us home, I am extremely happy with them and their crew. The only one person that I would praise within the entire part of BA is the girl I spoke to in the call center in India. Who completely understood, was dedicated to a resolution and was a complete realist in the situation. Unlike some of the people who don’t care about the human element and stick you on a flight whenever. She got us home.

Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.

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

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.

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

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