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

Other than the airline changing my aisle seat to a middle row, all else went well.

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.

being late for poor reasons, bad chairs, being regulated to a terrible gate in LAX

Rude staff from baggage check to gate crew. Poor instructions. Inconsistent application of baggage rules.

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

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

They did everything right and everything happened right on time.

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

My only complaint on any flight is meals but your gnocchi was good. The worst is breakfast. I can’t understand why you don’t just serve something simple like yogurt, fruit and a muffin or cinnamon roll.

Amazing, crew are very friendly and they gave us blanket and sleep aids and plenty of drinks and snacks

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.

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

Bid process for upgrade is very frustrating. I was notified that I had won the bidding, then was told there was no seat available.

Really like this airline. Best food for airlines and comfortable seats and attentive staff. Delay was due to air traffic.

great crew, professional, funny, and great service. good condition plane too! great experience

Very difficult to clearly hear the dialogue on videos due to airplane engine sound. Flying to Copenhagen audio was very clear. Food was excellent. Returning flight--Lunch and breakfast food was the worst I've experienced. Audio was terrible. Why the difference?

Travelling coach, comfort is all in one's perspective. Movie choices were great. Food was OK. Flight crew were pleasant. Tip: If they come through asking if you want tea or coffee, do not ask for water. They get miffed. So use the call button after they pass through.

The plane is extremely cramped. Water is offered for free. It's pretty bare bones. Staff was nice

Paid for seat upgrade that didn’t happen. Large luggage charge. No food or snacks without paying extra. Tight seats - even on row 11.

The ticket was reserved in my name but not paid for by underpricer. Alaska airlines was unable to issue my ticket (could not connect the ticket with the PNR) due to an error with underpricer and I spent the better part of 2 hours at the ticket counter trying to rectify.

Everyone at icel air just passes the buck if there's a problem which there was they don't want to know about it any company can be good if everything goes well it's what shows is when something doesn't go well how they handle it and trust me Iceland air does not know how to handle any kind of problem

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

They wouldn’t check in my luggage even though I had one checked bag prepaid. So I took my bag to the gate and tried to check it in there and two employees scolded me for bringing a large bag to the gate. I told them I was trying to check it in and that it was prepaid, and they said they couldn’t guarantee that it would arrive at my destination but they finally let me drop it off when boarding the plane and pick it up right after exiting the plane. There was no food, and there was no entertainment.

They had a 4 hour delay and left my luggage in Iceland and it didn’t arrive in Portland until 11/1

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

Highly disorganized company, poor customer service. Packed seats on a 737 for a trans-atlantic 9 hour flight. Greedy company policies, no meal or snack provided for 9 hour flight.

Everything was terrific. Kevin, and the whole crew, were exceptional. Five stars all around! Thanks so much.

We had a fantastic crew, super friendly and very helpful but the actual boarding part of it was terrible. You actually felt like we were going to a Third World country to be honest all the way up to the airport and the way it was split up going in all different kinds of directions and no one knew what they were supposed to do was extremely stressful

Decent flight, helpful middle seat blocking in business. Boarding staff was polite and helpful. Unfortunately the airport directions to this gate were a mess and the check in staff did not alert us to the confusing signage or any proactive information about the lounge. On board the flight, food and drinks were decent but average. Comparatively, SASs new business catering on this route shines above both in quality and service

ok. It's a short flight and it was delayed, hence the ok rating.

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

Not only were the aircrafts spacious, but the crew was friendly and efficient. I was so gracious for the included meals on the longer flight (8+ hours).

THE CONFIGURATION OF THE BUSINESS CLASS SITS ARE AWFUL!!! I WILL NEVER FLY BUSINESS CLASS ON BRITSH AIRWAYS AGAIN.

Honestly it was not great. I bought the plane tickets months prior to flying. The trip there was fine, though I found the mini beer offered on the flight a bit chintzy. The food was actually quite terrible both ways. I suppose that is somewhat to be expected. However, the return flight experience was awful. They did not have a seat assigned for me so I ended up "Flying Standby" on a flight I had purchased tickets for. This only complicated things when we arrived at Heathrow where I had to be assigned a seat on the next plane before getting through security. That added 15 minutes to the ordeal because there was no one to answer the phone for the security personnel. The security lines were backed up because people. It took another hour to get through and I almost missed my return flight due to them not having assigned me a seat number. Stupid.

Food not so good. Need more veggies and whole grain especially the late food. Couldn’t figure out how to use the entertainment system.

Boarding was organized and fast. Food was good and service was great. Tight seats and packed flight.
