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.

My experience was very good. Everything was excellent except for the food. The food was mediocre. Not alot of options and the flavor was okay.

Had to deplane 2 x due to problems with plane. Delayed over 6 hours ans was given a $12 food credit which barely oaud for anything and limited to wear incoukd redeem.

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

No beverage/snack service without any explanation or reason. Late boarding and delayed flight.

more room in seats, larger snacks, more comms with delays

There was overbooking that delayed boarding. Then an airport emergency lockdown that caused further delays in boarding. However the time was made up during flight and there was a minimal delay in landing. Everything else was excellent.

Delta is the best. It was all very easy and on time.

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

I booked a round trip with Delta, and each of the four segments was sold off to three other airlines. All four were late or cancelled, so I had to troubleshoot with three different airlines, NOT Delta. In fact, even though I had paid money to Delta, they could not help or troubleshoot anything. Not nice.

Bought a round trip from Delta. They sold all four flights to other airlines. All four flights were late or cancelled. I had to deal with Delta, KLM, KLM City Hopper and Germain Airlines for problem resolution. Very disappointed in Delta in dealing through these issues.

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.

The layover was very long. Other than that, great trip so far

We flew economy+ and it was a great experience. The crew was friendly and helpful, there was a great selection of inflight entertainment and food/beverages.

Business class flight attendant was very good. But our flight was delayed two hours for a “mechanical” bathroom issue that literally took 5 minutes to fix. Our plane landed early from its previous flight but still waited for a mechanic to show up to fix an obvious minor issue for almost three hours. This caused us to miss our connecting flight. They put us up in a Days Inn that was 17 miles away from the airport that took a half hour of driving just to get to and this was at 11pm at night. Then when we finally got back on a plane after a full day delay they left our luggage back in the airport. This was an international flight, so no luggage or belongings after flying 8 hours to a different country. We will NEVER fly American Airlines again.

12 hour wait in pdx to my initial flight to Dallas to hunstville

I was able to enlist on standby for an earlier flight, and eventually made it (last row). However, the experience was poor and felt unfair. On the standby list, I was ranked #2 (#1 had been cleared a seat). The person ranked as #3, who was also in the queue alongside me was given a seat much earlier - with group 4 boarding (a seat within the first 2 rows after business class). When inquired about why I was skipped-over on the priority list, the gate agent first paused (likely cuz she couldn't explain) - and then gave me the standard expectation that if a space opens up, she'll give me the seat. Despite my priority ranking being higher, I was unduly held-back, and could have missed the plane - unfairly giving advantage to someone else. Luckily one seat opened up; but given the unfair assignment of standby seat by gate-agent, this was a subpar boarding experience.

The airline was small and the seats were not comfortable to sit in for that length of time.

Everything was fine except they changed the gate number and we ended up running all over LAX because of it.

Flight DFW > CVG was delayed with late notice. My flight into DFW from CVG (previous) was delayed by multiple hours with very poor communication & advance notice. And having the flight attendants announce the credit card during the flight when I can't opt felt very insulting and cheap. I already paid you for the flight, you shouldn't be able to take my time and attention hostage for further advertising.

Im sitting here waiting over an hour for my golf clubs

Flight was 2+ hours delayed and they “misplaced” all 3 of our checked-in bags.

It was freezing in the cabin. That's on me to be better prepared in the future.

It was very good. The flight was delayed and people that were boarded needed to get off again but overall it was very good.

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.

Flight was delayed 4 hours, gate change was a big trek the opposite direction, gate agent indicated a lack of faith that we would actually fly.

Wonderful service and comfort. Attentive and careful. The food was also better than US carriers. Highly recommend

Very good baggage check and boarding pass service at Heathrow. Boarding was well organized, given the number of passengers. Food was very good. Cabin temperature was lower than expected and we were not prepared. Overall good experience.

one meal and one breakfast or sandwich instead of two meals.

Many issues arose with the plane and after 3 hours of delays, we had to return to the London airport as the plane was unfit to cross the ocean. It was highly concerning that this aircraft was in operation with so many problems.

You're asking 2 different questions. The flight from Los Angeles to London (and from London to Faro) was on British Airways. Those flights were awful. The app didn't provide detailed information, the WiFi that I paid for didn't work, the form I had to fill out to re-enter the UK was not communicated clearly so I nearly missed my flight. British Airways is significantly behind every other airline I've traveled in every way. American Airlines flight form London to Los Angeles was great. In the future, I will avoid flying British Airways when I can.

The calls for our boarding group weren't heard/clear.
