I still prefer Delta, but Delta doesn’t fly to State College PA.

I still prefer Delta, but Delta doesn’t fly to State College PA.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

United needs to figure out its Economy PLUS standards; its better than economy but that's not saying much. It seems like United stripped away all the basics for an international flight (such as In Seat entertainment) and repackaged some of them as plus. Would not fly United internationally again.

The flight was bumpy. No Breakfast or coffee was served, not even a bottle of water. The food was okay but odd. Rice with peas instead of couscous with some unknown green thing. United Airlines did not tell me that there was VERY LIMITED HANDICAP SERVICE IN NAPLES. De-plane via 20 aluminum steps. Taken to Van. You must walk into the terminal, find luggage, and then walk out to the rental car pickup spot that is 1 block from the terminal.

Crew did their best but the plane configuration is too tight if you're bigger than an average sardine. Controls for the entertainment system didn't all work. The aircraft hadn't been cleaned in awhile.

Flight was delayed due to weather and clogged toilet. Had to deplane. Flight was 3 hours delayed. Crew was awesome and offered water and snacks.

Didn't make it dir to delays - no support from United staff

Horrible! I paid for a straight flight from Chicago to London. A week before trip it changed and now I had a connecting flight. Our flight was delayed an hour and a half because our flight crew was still flying in from CA. Forty passengers ran from one plane to the next. The next United Airlines flight was delayed two to three hours because of mechanical difficulties. They had to ready another plane which took time. I missed my scheduled excursion in London. 😢

My flight was delayed for a whole day, so I lost a day of my vacation.

United cancelled the flight after a 2 hour delay. The only choice was a 24 hour delay which was then 3 hours delayed.

Had recurring problems with the touch-screen entertainment system repeatedly making up inputs, resulting in the movies randomly jumping forward and backward. With the lack of proper controls, it was also difficult to get back to where the movie was up to. These phantom inputs were so comprehensive that the system even changed the language setting. Despite a schedule 6.25pm boarding time, it was announced in the Delta lounge at 6.15pm that boarding for the flight had started, so of course everything started to head down. While the gate continued to show a scheduled boarding of 6.25pm, it was 6.32pm before boarding actually started. No, not significantly different, and we ultimately ended up landing well before time (and landing time is arguably more important than exactly when boarding starts). Seat comfort was fine, although only a small nook for personal items, food was satisfying for me, and crew was pleasant.

Entertainment system caused delay. But order was restored within one-hour into the flight. Service was good.

I did not go. I rebooked my ticket. Despite that you keep sending me emails and now this survey about a trip that you should know by now did not happen. Very bad, impersonal customer service. Shows you have no idea what's going on with your customers and that you're just spamming with automated, careless communications

Flight delayed 3 hours 45 minutes. Connecting flight changed. Would have missed cruise ship. Had to cancel return flight, because we couldn't just cancel flight to Nice.

Pilot made us late 45 minutes with no explanation, missed our connection, they didn’t care

The flights from EWR to Stockholm and from Copenhagen to JFK were great. Love everything from SAS

First off, numerous things were misrepresented. When we purchased the Economy Plus tickets the fare allegedly includes access to lounge. At Logan Airport where the signs points to, there is no longer SAS lounge. We were directed to Delta lounge, which is located at the other end of the terminal. When we got there, Delta reps told us that it is for SAS business class passengers only. The advertised seat selection 30 hrs prior to departure did not work online. When I called SAS, they told me that it was more than 30 hrs before our connecting flight in Copenhagen, although it was less than 30 hrs before the departure for Copenhagen. Customer service representatives would not provide any assistance. The tray table in my seat was not fully unfolding to be able to place the food tray on it. Therefore, I had to keep it on my laps.

It was a rather short flight. The meal given was a sandwich which did not look appealing at all. Unlike other European airlines, SAS did not leave the middle seat empty for the higher fare paying customers. Luckily since the flight was light, I could move to another row with no other passenger.

This is my fifth time flying with SAS and I love it

The employees were very nice. I liked my bulkhead seat. The flight was delayed unfortunately. It was a smooth ride. I was prepared for a cold plane with extra clothing. I assume there is no way to make it warmer.

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

One of the worst airlines I ever flew. Boarding is a disaster, they are always late, the planes are overly crowded. Everyone on my flight lost their connection because they were 2h late. Reykjavik is also not the best airport out there.

Been travelling for 2mo. And when you meet flight Attendants that love their jobs you can just tell. And makes flying with them worth another flight in the future!!

Everything was great! My only critique is 25 euro for wifi is wild, but I get it

Easy check in and boarding. Staff pleasant and helpful. Will continue to fly with Iceland air. Aircraft clean

Most of your crew was very helpful just one young lady wasn’t, but all of the ones I dealt with were great. We had to buy food on a six hour flight and considering we had a three hour flight before this one I felt we would have a meal included. I ordered a sandwich and by the time I got it, it was quite soggy so couldn’t eat half of the sandwich. Other than the food, or lack of, the flights were great.

Late start due to so called cargo door, super expensive meals and baggage check( only airline where meals and baggage is charged on long international flights) slow baggage delivery at end a lot of employees at airport standing around talking to each other.

7 hours 15 min flight from SEA to Iceland with no inflight entertainment and no power to charge your own devices, also no meal service, not even any snacks/cookies. You have to buy food and the options are extremely limited (i.e. ham and cheese sandwich and spicy cup noodles). I didn't think Iceland air was a budget airline, maybe I was wrong, the cost of the ticket didn't feel like it though.

Horrible. I was placed on standby for no reason and they would no allow me to fix the seating into the gate. Plane was hot. Entertainment was abysmal. Seats only take old USB or even older jack plugs — not lightening plugs like all modern phones. Food is pay as you go and awful. Seats were small and uncomfortable. I do not recommend Iceland air.

The cost for the flight was quite reasonable and transferring to a new flight in Reykjavík went smoothly. There was enough time to grab a bite to eat at the airport, and the luggage transferred to the new flight with no problem.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

We couldn't talk to aer lingus we had issues with the flight change and aer lingus made us talk to kayak

Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

Amenity kits were never handed out. There was zero friendliness and assistance by crew. Food was uneatable. One drink was offered and no wine, with dinner or before or after. Cocktails and beverages were not encouraged and when I asked for water, none was given. Poorest, most cramped business class flight I’ve ever been on.

Loved it! Best airline to fly with. Nice crew, good planes, good food!

Probably my favorite airline and way to go to Europe. Everything went smoothly! Food was tasty, crew was pleasant. Really cannot complain!

Horrible. Garbage airline. Due to the strike we got a replacement plane/crew. I didn't get my exit row seat I paid for. Food was horrible. Plane was hot and didn't have AC vents.

Great customer service. Frequent updates from the pilot. Smooth flight. Good entertainment. Meal service.

The first leg of my 2 flights were delayed, causing me to miss my second flight and have to stay the whole night in Dublin. Super upset with this experience, and I still need to figure out how to get compensated for this.

Not good. They charged an additional $70 to check a bag we had already paid for on line with Lufstansa

They gave us free up grade to a roomier seat.

A major problem at the Frankfurt terminal. You see your connecting flight is on concourse A and you see signs for A, but when you start to walk out to A, only then do you find A is in another terminal which requires a bus ride, passport control and customs. If you sit around in the first terminal too long, you can miss your flight. We made ours.

Connecting from Germany with not enough time to go thru TSA and security so many times. Kayak or whomever doesn’t leave you enough time between flights. I made it with 5 min before my zone was called. Too stressful

Staff very helpful. Seat comfortable. Food generous and pretty good.

Connection time and departure time were both changed to cause undue stree on older people who cant run through an airport

We were delayed so long that I missed the next flight. I should’ve arrived in Catania at 4 o’clock and arrived at 1 AM. The late departure was due to a water leak due to a dirty filter, according to the flight staff, and that seems like something that should’ve been taken care of before the flight. It’s too simple of a mechanical problem to make you miss the whole day.

Liked nothing. Rude staff. Incompetent crew and workers. Wont fly with again

Everything was fine except the landing. We were off loaded on the tarmac. Squished on busses then driven around for 20 minutes. Dropped at terminal B and needed to be at A so had to wait 20 min in another line to catch a bus then another 20 min wait in customs! How on earth were we to get to our connecting flights!? Not a great first trip with your airline or start of my vacation. The woman on the tarmac was rude too

Seats were very small and of poor quality. Service was good.
