Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

Seats were really tight and the seat belts did not give enough slack.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

You cost me my time and did not compensate properly. Gfy.

Missed a connecting flight and SAS was at fault. I was awarded a $20 voucher in exchange for 8 hours of my time? Gfy.

Seat was lumpier than I’ve ever remembered it to be although comfortable when tilted back. I don’t recall being that hungry after being served food from SAS before. Flight attendant on the second flight to Aalborg seemed to be having a bad day.

I experienced trouble with the automatic bag check in. When I scanned the baggage tag I received, things were fine as the conveyor belt moved forward then abruptly stopped! My luggage traveled about 4 feet and I had to reach over a barrier to retrieve it. I went to another scanner position and when I scanned the SAS baggage tag, the screen told me it could not continue!! I went to another scanner position agent who had me put it on the conveyor belt by her & somehow sent it down the belt. I flew from Bergen to Oslo with a two 2️⃣ hour layover before connecting to LHR. My bag was NOT on the flight. I had no clothes for the next day when I flew to Boston. I filed a Lost Bag report and waiting for updates.

Please see my comments for the flight from Chicago to Copenhagen

All flights were on time! The crew was nice and polite Thank you. Food was awful. They give you terrible pasta or rice dish and make you pay for chicken if you’d like meat. When I asked for water with my tea, they told me, I’d have to pay 3 euros for water. Restrooms were filthy half way through the flight.

We were sitting in SAS plus. Super friendly, service that went above and beyond on a Full Flight too! Meals were deliscious and trays were cleared promptly. Generous drinks offered throughout the flight. Would like to suggest better movies on offer to watch.... In all genres and maybe more cooking shows? There was only 1, Nadia's Everyday Baking... Thank you

The meal offered was fish. I am allergic to fish. When I told her, she just took the box of food back without offering me an alternative.... I had to ask... can I then have a bag of chips? She did give it to me. I am a Euro Bonus gold member. Please just take the time to offer something else. Easy and from a customer service point of view, .... Considerate.

It was ok. Vegan meal was good, however no complimentary alcoholic beverages.

The food service was absolutely rubbish. Very arrogant crew. Does Scandinavian airlines think everyone eats meat??? I paid for my flight but could not eat anything because I am vegetarian!!! I was hungry for 7 hours . I demand for refund! This is absolutely unacceptable!!!! If you want more customers keep an open mind!!! Cater to all meal needs. I have flown many airlines and I never make a special request online never! They always have vegetarian options. SAS has no idea of customer service. Shitty service

This was a pleasant, short flight and the crew was friendly.

Very poor. Our special services attendant gave us incorrect information. I also was mishandled at landing. There was no wheelchair waiting. I fell deboarding the plane. Appalling!

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

Boarded over an hour late, no communication, the sign just changed, no attendant to answer questions - she disappeared forever (hiding). Small plane and couldn’t hear the overhead nor understand.

Service in first class no longer exists on American Airlines .

Customer service in first class does not exist on American Airlines

I never have a good experience with American and this was no different. The airplane was INCREDIBLY hot. Like unbearably so. Everyone was fanning themselves with pamphlets and sweating. When someone asked the flight attendant to turn down the temperature they were told there was nothing the crew could do. Once we pushed back from the gate we then had to wait an hour to take off and the communication from the crew was not good. People were getting up this whole time and a man was even in the bathroom when we took off. Once we landed at our destination we waited another 30 minutes at the gate to deplane with, again, no communication from the crew as to what was going on.

Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.

First, to be fair, the flight was on time and the trip through the air was relatively smooth. But the flight was full, and they were checking carryons. As this process went on, the crew got increasingly rude and overbearing. During the drink service, a young girl (maybe 9) who had gotten up to use the lavatory got stuck behind the cart. At some point, she started feeling fearful and overwhelmed. Passengers noticed this and asked the crew to let her return to her seat. They refused. Then she started crying, and they still refused to move the cart forward to let her sit. The poor girl was trying to be brave and compose herself. The crew handled the situation terribly and with zero grace or decency. That episode, to me, encapsulates AA’s attitude toward its passengers. Disgraceful. The plane itself was cramped and miserable, as usual. There was zero inflight media or entertainment, other than the lane and borderline inappropriate jokes the steward made during the safety briefing. Then, of course, it took the better part of an hour for the checked bags to show up at the carousel. AA is no better than the el cheapo airlines these days and a far, far cry from its former self.

Only serving 2 small coffee in 7.5 hrs flight with very limited choice to order food.

Overall good. I was surprised how easy it was to get from plain to plain in such a short time. Food choices were not so great and quite expensive. Entertainment was ok. Flights were smooth.

Our three ski bags did not arrive and are still not delivered, one full day later. With one ski bag not traceable at all. I would not fly Iceland Air again.

Horrible. The flight was delayed by over 3 hours but updates were barely provided. Boarding started 3 hours late then stopped because their system crashed. So now, passengers were standing for 15 minutes in the open waiting to get boarding passes scanned and get on a bus. Duty-free closed around 4-4:30. Only 1 food outlet was open and it was super slow and busy since it was serving passengers from multiple flights. So a number of passengers couldn't buy meals at the terminal. Since the flight was delayed by over 3 hours, we could have been offered snacks on-board. Nothing. The seats barely reclined. In-flight entertainment options were pitiful. Overall, a miserable experience. Never flying on Icelandair ever again. :(

Bad. Flights were late, by hours. No clear information was provided even until the delayed boarding time.

Again, lines for boarding are a problem in iceland. The flight itself was fine and very smooth. No complaints. We would definitely fly icelandair again.

Had a screaming child next to us. Not the airline’s fault but still annoying.

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.

Icelandair flight was excellent. The checkin and security arrangements for Saga Premium passengers at Newark was very poor - our checkin opened much later than the normal and our security queue simply led us to the back of the normal queue. Someone was having a laugh surely!

Never took flight. See previous comment on trip from Boston to Reykjavik. Used a different airline that i had to find and book.

The crew were professional and friendly. It was the most uncomfortable international flight I've ever flown. Crammed in passengers. No overhead space to put my bag. No leg room and unable to recline seat due to seats too close together so it upset passenger behind me! Upgrade price to get 2 inches of more space unreasonable.

Boarding in Dallas was hell with extremely rude gate agents , especially a lady named Rajathi who was the epitome of rudeness with no compassion at all . She was horrible and I wonder why airlines have people like her on their roster who exude arrogance and haughtiness . Will probably not fly British Airwsys because of people like her .

Less than average, low level of shared required information needed during the transfer from airport to another, also the used team during boarding In Indianapolis station is Not Professional

Food was average. Better headphones seats were average at best.

Nice flight. Legroom was good. Food was good. Staff was friendly and helpful. Plane was modern and clean. Seats and headrests were comfortable. Entertainment system was good and modern, with a bright LCD screen and many appealing choices.

I have something to say about the flight I took from London to Gothenburg, after my flight from Austin to London. I fly a lot and have done so for decades. I first flew to Scandinavia in 1973. My former wife is Norwegian. The main thing was the experience at the Gothenburg airport. Three flights from Britain arrived around the same time. So there were huge lines at immigration since Brits are no longer a part of the EU. After over an hour in line, I finally gave my passport to the immigrations man. You’d have thought I was an Afghan. I just barely got into Sweden. I had to answer all kinds of blunt questions. I had to show all kinds of onward tickets, addresses of places I’d be staying and it was pretty daunting. Perhaps it has to do with the situation with Russia. British Air might have done something to prepare people that things have changed a lot and they’d better be ready to run the gauntlet when trying to get into the country here. Thanks for listening and taking this into consideration. Sincerely, a senior citizen of the USA

No land services during boarding, specially while moving from terminal to another

My flight was late. We stayed in aircraft one hour 😩

Flight delay and can’t much help passenger do the change connecting flight.

Even the carry-ons were not allowed and upon getting down, we had the wait for the longest time for the baggage to put on the jet aisle. We had a short connection which British Airways kept changing and made out entire experience poor. I would never fly BA again.
