They lost my luggage and there is no update, no luggage and no hope that they will find it. It has been 26 hours since we landed

They lost my luggage and can’t find it. My trip is ruined. Online tracking of lost luggage doesn’t work

No free Wi-Fi. I have SkyMiles but not a high status, having an account has been enough for Wi-Fi on other flights, but this one was going to charge me to use it. Also turbulence was really bad toward the end, but I didn't count this in my ratings since I know Delta cannot control the weather - it's 2026 and lack of WiFi alone is enough for a poor rating.

The stewardess was incredibly rude. The gave you only one drink with dinner.

Cancelled flight, wasn't refunded paid selected seats. Poor customer service. Called airline and they didn't realize the flight was cancelled until several hours after the email notice was sent.

The worst with the trip was the space in economy, my knees are still hurting. There was no way to control personal air by turning a knob above you, it was way to hot on both rides. During the night flight they allowed 2 people from across the aile which was narrow to sit and talk for 7 hours while also using tablets and the flashlight from their phones pointing into the row where I sat at times. They allowed people with way too large baggage to bring onboard. I paid way too much for the ticket ($1,364} for economy. Kayak misinformed me to get cancellation insurance that was only valid for a very short time (less than 12 hours) and was over one hundred dollars. Hotel booking was incorrect, I had the room booked myself at the hotel, only double or larger rooms available which I paid over 400 dollars for. I will never fly with SAS again unless there is no other alternative.

Crew members were excellent. The seat wasn’t the best as well as a food options.

5 of my 7 pieces of luggage are missing and they cant call to find out where it is. I have to fill out a form and wait for them to mail it to me in several days (if they find it). That does not work for my travel itinerary. I need my full ticket cost refunded please.

Fantastic. The only thing - out of my six luggage one was lost in Copenhagen, however it was delivered Home 3 Days later so all great..

The crew was friendly, the flight was pleasant. Thank you for your service!

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Crew was friendly. Seats are too narrow, particularly when a big person is in the adjacent seat, but I understand this is due to smaller planes usually flight into Lincoln. I have experienced several flight delays going out and coming into Lincoln airport, I say maybe 50% or higher of the flights I've taken out of this airport have been delayed.

Great flight. Boarded efficiently. Arrived early at CLT. There was no in flight entertainment on this aircraft. Great crew.

The seat was comfortable. There was a lot of turbulence. If it weren't for that,it would have been okay.

Poor communication, flight was delayed for preventable reasons. I missed my connection.

The boarding timing needs to be improved. The flight was delayed again because it took way too long to board. I was already exhausted from sleeping at the airport and spending all day there due to delay from my previous flight that connected in Chicago.

We were an hour and a half late, which caused my rental car company to cancel my reservation. We had no car, had to take a taxi to our hotel, and then a taxi back to get a new car the next day. Sometimes lack of on-time performance can end up costing the passenger a lot of money, none of which is covered by the airline that operated the late flight.

Overall good experience. But seats were small and uncomfortable for the price. Good entertainment, staff friendly and attentive.

Smooth quiet flight take off and landing both excellent. Food was mediocre. Boarding at gate was disorganized and unacceptable.

Very good trip. Nice clean aircraft. Helpful and friendly crew.

Crew members Grainne and Karen were extremely rude and unprofessional

I am very disappointed in that KAYAK sold me this flight as a business class it was not a business class. It was a regular economy class ticket. This was not Art Linus mistake. It was kayaks.

Crew was friendly and seats were comfortable. The connection however there were no free snacks or drinks.

Our flight from Dublin to Coruna did not exist any more. Apparently it was cancelled in February and I was not advised, nor was I offered any flights for rebooking. Happily Aer Lingus found another flight to another city in Spain that was 500 miles from Coruna; I had to pay for a hotel overnight and a revise my rental car that incurred additional costs, and I did not get to Coruna for another 24 hours. I was not at all impressed with Kayak or Chatdeal or Hertz.

OK overall. Flight was delayed Crew on flight was good

Late late late. Delayed and arrived an hour late for a 1 hour 45 minute connection. Every time. Poor record for this company. I try to fly any other carrier first.

They cancelled our connecting flight resulting in another layover reaching our final destination 8 hours later than scheduled.

The Check-in process at CDG was confusing and the crew was not helpful. But the flight was on-time and that is most important to me.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

Was a bit surprised that Icelandair flies a domestically configured 757s on long-haul flights to Iceland (no lie-flat seats in business class).

When you consider the price I ended up paying for everything. This was not a good deal! I had no idea that this airline had changed to a bargain basement no frills airline. So, it was disappointing to have to pay for every little thing. The only thing included was water and coffee. You have to pay for everything else! So I just felt nickel and dime.

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

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

Second time with Saga Premium, everything was fab, but the entertainment centre on both my flights didn't work, plus the seat on the NY to Rek flight (Airbus) was so solid and so uncomfortable. The 737Max flight's seat was much, much better.

I’m considering never flying with Iceland Air again. The seats in economy are torture. Now you only get water, coffee and tea for free- really? No food, not a single peanut. The passport line was insane, everyone was worried about catching their connecting flight. This was the third time I’ve barely made my connection, had to run. It can’t be that my choice is to use the bathroom (during the 50 minutes between flights) or make my flight. SO stressful! Ugh.

The most uncomfortable seat i’ve ever had on a flight

Put me on standby; flight was late; missed my connecting flight; disaster

Flight attendants were fine, seats a bit hard but I use a cushion for extra support. The only issue was it was a bit too cool and I needed to ask for and received and extra blanket. I survived!!!

Very few things and/or people are excellent. It was very good.

Extremely uncomfortable seats. Experience was like a Frontier Airlines flight. Would not fly it again.

Very, very tight legroom. They must’ve jammed in an additional few rows of seat seating. Denver to Munich was the least legroom I’ve ever had on any flight, let alone a multi hour international journey. I will not take that flight again.

Good food, overall very comfy. The flight was full so obviously not optimal, but it is what it is.

Parents with permanently crying baby on board. Neither parents nor crew did anything to calm the baby. The food was extremely disappointing. Seafood stew was very, very small! Not even appetizer size! Seat had a gap in the back. Had to use a pillow to fill it.

Food choices limited & not enticing Seats quite uncomfortable & difficult to control

Definitely get premium economy on a flight this long if you can. Your legs and while body will thank you.

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers
