I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.

I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.

The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Flight lead was a gentleman with silver hair and he went out of his way to shake hands and interact with each passenger seated in business class. A medical emergency took place during our flight and he handled it with perfect poise and professionalism. He was gracious and confidently competent. Just what you want from a leader,

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Great as one can be for a one connection 6 hour flight

The gate attendant was not clear w message on flight delays.

Chairs don’t recline and the ones that do recline, barely do recline. It was most uncomfortable flight i ever been on.

Good service but not on par when compared to foreign flag carriers.

Travelling with 2 others for work. Delta asked to check their carry ons due to the fullness of the plane. This was all good until the next leg of the flight. One of the 3 had their carry on checked through to the final destination but their passport on in their checked bag. Which they could not get to and he was not allowed on to the plane. Even though Delta had to retrieve his bag, because he was not allowed on. So they got his bag and he was in the terminal, but even when the flight was delayed, due to mechanical issues, he was not allowed to come onto the plane. Since the delay was nearly 2 hours, he was finally allowed back on the plane.

good in general food is just snack and beverages (same snacks all the time) could you try to change them?

We experienced delays in small increments that added up to more than an hour. At the gate, staff showed little concern and compared our delay with the inbound flight’s two-hour tarmac wait, which didn’t address our situation. Once onboard, the flight attendants seemed tired and unfriendly. I understand delays are frustrating for everyone, but passengers shouldn’t feel blamed for them. During the flight, a bright light above the emergency exit stayed on. It was concerning, and no one explained it or offered passengers the option to move. After landing, we waited about 30 minutes on the tarmac for a gate, then waited again for an agent to connect the plane to the terminal. From the Reagan gate staff to the cabin crew and RDU personnel, the service felt dismissive throughout. Overall, this was a stressful trip and a very disappointing customer-service experience

My flight from Atlanta to Oklahoma City was delayed multiple times. I ended up arriving in Oklahoma City nearly two hours later at around 1:50 am the following morning. This was a highly disappointing experience.

My Delta flight 2423 from Atlanta to Oklahoma City got delayed multiple times. It was originally scheduled to depart at 10:41 pm EST with a 11:58 pm CST arrival in Oklahoma City. However, after multiple delays, the flight finally departed Atlanta at around 12:40 am and arrived in Oklahoma City at around 1:50 am. What was even more disappointing was that none of the crew members acknowledged, let alone apologize, for the delays. These delays were not due to weather and were only due to operational/mechanical issues on the part of Delta. As a former Platinum SkyMiles member, I valued loyalty with Delta. However, after having similar experiences in the recent past, I'll be switching my loyalty over to American Airlines going forward. This was a highly disappointing experience.

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.

I feel SAS is the only airline that does not let you choose your seats when you're checking in, and so we were forced into two middle seats and it was quite uncomfortable. There are not enough new and quality movies available on the entertainment system. After our inbound SAS flight being canceled with less than 12 hours til departure, the whole experience flyign with SAS wasn't great.

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

SAS cancelled my flight SK910 on Sep. 21,2026 because a construction crew from New Jersey Transit accidentally cut through a fiber optic cable which enabled the control tower at Newark Intl. Airport to communicate with all flights. Over 600 flights were cancelled including mine. My boarding code was B2WJMJ, I demand a refund of all monies spent toward this reservation!

More movie options More friendly responds to passengers requests More stops from crew inside airplane

Didn't care much for the food but maybe that's just because I'm American and the food was very European. Would have liked a second alcoholic beverage service in a 7-8 hour flight. I was offered two wines to have with dinner though and should have accepted both. I didn't realize they would only offer alcohol once. Lights were never turned off in the cabin for sleeping. Flight was delayed several hours with zero explanation from SAS. However, the flight attendants were fantastic. We were traveling with a friend who needed oxygen and they were very attentive and helped him throughout the flight. That was greatly appreciated. The pillows and blankets are great. Gift bags with toothbrush etc so nice! This was our first time traveling Premium so alot of perks we were used to getting! The flight was smooth and I loved watching the planes location on the seat screen and being able to watch movies etc. overall it was great I would definitely recommend SAS to anyone and hope to fly with you again sometime.

Food was excellent and plentiful! Cabin crew seemed to truly enjoy their job. Interacted with passengers with a friendly nature. Very pleasant flight

they had to land at Dulles instead of EWR and had no one to help all of the stranded travellers the crew was rude and not helpful as well

The layovers / connections were too short and too long. I SPRINTED to make the connection from OSL-JFK and then SAT for over 6 hours from JFK-BUF. I don’t mind a longer layover more than I want to RUN to make my next connection

Our vacation started with horribly, 48hr prior to departure SAS airline cancelled our return flight giving us little to no alternative options.

Nothing available at the assigned hotel as far as brush, toothbrush, etc after forced layover with bags that departed

Crew tried to accommodate late arrival due to late departure

The now boarding notification was not updated in the app until I was actually on the plan. This si a massive fail considering my flight was delayed several times. These types of failures add stress that could be avoided since I no longer feel comfortable leaving the boarding area to get food or visit a lounge. Had I used the notification from the app, I would have missed my flight. The secondly, the process of connecting to wifi on aa flights is clunky and could be streamlined better. the copy and past process feels like MVP, and you are well beyond that stage.

American Airlines flight was cancelled and ended up on a Royal Air Maroc flight and had to pay for things that wouldve been included if I was on American Airlines since I have status

I injured myself during my trip. The staff of American Airlines were very compassionate and empathic. They took additional steps to make my experience easier. Thank you!!

The ridiculous extra security checkpoint at the gate after already going through one was very unnecessary! Also, the last meal (breakfast), my preferred meal option, the flight attendants ran out at row 3 and they have complained about this being an issue on this flight for months! Please have it addressed and stocked appropriately!

Poor service. Check in person at the COUNTER was ruthless and threaten to call police instead to look for better plan or actions. VERY MANERLESS lady. KICKED US OUT OF OUR RESERVATIONS. ABSURD

AC wasn't working properly and the WiFi was also not working properly for stretches.

Flight was fine. Just delays leaving due to mechanical issues. But flight crew were kind and professional. Seats were spacious. American doesn't need to have 9 groups for boarding.

Both flights were late leaving due to repairs/switching gates. The crew and pilots, however, were professional and courteous. Most importantly, we arrived at our destination safely. The seats were comforable. That size should be standard for all economy class. American could improve its boarding process. I am not sure why you need 9 groups for a small regional plane.

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.

It was fine, but it cost me twice as much to return to Boston as it took me to get to Heathrow from Boston two weeks prior. I flew on Jet Blue over and it was half the cost of British Air.

Staff and comfort were great but first choice meal was unavailable even in row 21.

I have flown on British Airways, many many times and will continue to do so! Always the greatest service and staff!

canceled flight. needed to fight to get same fare class. now they have canceled return.

Cabin crew was very good. No wifi and no doors to the suites

Would not let me board with my fragile guitar so had to check it in. Who knows what the icicles did to it. Not happy. Had to run to catch my connection in Heathrow. After a bus and a train? Was asked by a guy in the middle seat to change my window seat with his girlfriend's middle seat further up in the plane and I was insulted. What nerve! The food was unhealthy and the seat was cramped. Could not wait to exit.

need more US friendly food options. Directions on getting to the next gate were terrible - resulted in long walks to the terminal and then finding I couldn;t enter there and had long walk back, then train to security then train back to where I started in the first place

Good. Staff was great. The Naples Airport was the worst part of the experience.

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.
