On time. Carry on and personal bag was accommodated on the plane. Entertainment was accessible without bringing own device. Whole can of juice was provided rather than a pour.

Price was crazy watch it if you Chan he your flight
On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.
Terrible service - they don’t want to be there and bad food. Entertainment system in economy from the 2000s
No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.
Flight delayed, last seat on the plane, no arrival Gate available due to the plane departing late
Kayak booked this flight with only 1h 20min layover in Chicago. This made it impossible for me and several other passengers to reach this flight. Moreover, the gate closed boarding in spite of several passengers still on their way without waiting even one more minute. However, the plane departed with 20min (!) delay, i.e., there would have been at least 15 min time to let the delayed passengers board without causing any delays. I complained and as a "thank you" the attendent booked us on the last (!) flight to Indianapolis ~7h later! Thankfully, I caught the spitefulness and the United customer line rebooked the flight to an earlier flight. Although I can't grade this particular flight since I never had a chance to take it, Kayak made the mistake of a too short layover and the crew at the gate was awful.
Flight did not have wifi service. It was experiencing technical difficulties. Definitely and old plane that needs updating.
This flight has a history of leaving late, however, I was pleasantly surprised that it was not delayed this day. The flight went smooth, except I was in a window seat and the wall and my feet were freezing. I found it difficult to sleep due to being so cold, I also was using 2 provided UAL blankets and could not get my feet warm. This was annoying, but I still made it there on time and safe.
Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.
The check in crew were so friendly and attentive. Probably the best in my experience and I’ve been flying at least four times a year most of my adult life. Very considerate and I appreciate it.
Absolutely the worst at baggage handling. Our baggage still has not been delivered. They couldn't find it in Dublin then when we got to Edinburgh they said the 2 bags were sitting in Dublin. After spending an hour filling out forms at the counter. We left for our hotel, bags arrived in Edinburgh at 505pm using my satellite tracker. Tried calling the numbers provided, no answer to their 24/7 service. Next morning the bags are still sitting at airport, no movement. Called different number provided by hotel in Sterling, the said it's souly the responsibility of the courier service now and they couldn't help. Completely ruined our travel plans, we must find clothes to purchase today instead of going to the museums we had purchased tickets for. This loss is costing us thousands in already paid hotels and services. No one takes any responsibility. I'll be contacting legal services on our return. We will never forget and I'll be a social advocate to avoid using this service.
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.
I flew economy class. Seats were very good and the crew was excellent
Fast and sensible boarding was absolutely amazing. But extortionate wifi and seats that barely moved, making me unable to sleep, didn't do a lot of favors.
I appteciate the very courteous staff. The flight was good. Something that wasn't good was that my bag was only checked as far as Dublin and I had a connecting flight to Vienna. (That was a mistake the ORD desk made.) Fortunately the desk at DUB was able to re-tag without me having to re-check in (which initially it seemed I might have to do.)
It was excellent! The plane left Chicago early. Arrived in Dublin early. The crew was excellent! It was a great experience.
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.
Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.
First class snacks - stewardess gave out multiples to everyone until there was almost no selection left when she got back to me last in first class cabin. Nothing left that I would eat.
My feedback from the trip to Columbia to Chicago was meant for Chicago to Denver.
The WiFi was out gr entire flight. Had to Diane for almost 1 hour to wait for a gate to open up for plane to dock. Very bad experience.
After boarding, the AC was shut off on the flight. At business class, I really could not breathe. I was absolutely dripping sweat. I was told by the FA that there was nothing they could do but I could stand by the door until departure. So, that's what I did. I was clearly in the way while the FAs were trying to do their work, but I had to be able to breathe. After that, of course, I had sweated up a lot so was very uncomfortable for the six hour flight.
DELAYED AGAIN and AGAIN and AGAIN - not only that, you delay in 20 minute increments for hours and hours instead of having an accurate delay understanding.
AA was fine....the overall experience was subpar, but not due to the airline due to broader issues
No ground air conditioner for the plane. Very hot and humid prior to take off which was an uncomfortable period of time.
Check-in process was poor, very poor, only one person to check-in all passengers, so if one passenger had a check-in issue, all other passengers were delayed. All check-ins should have two airline staff to check-in passengers.
The flight up was great no issues. The flight back home was a cluster. I was told the plane I was waiting on was giving to another flight which caused me to miss my connection flight. Granted the airline did great with getting hotel and vouchr for food.
Flight was delayed and so much of inconvenience related to the gate change.
The staff was very nice and helpful. Some of the best crew I have met.
Disaster. Downgraded. Zero apology. No effort or coordination between gate and crew. Awful seat blocked by door emergency slide box. Iberia is a mess. App never works. Avoid this airline.
It was extremely cold in the back of the plane. The seats are uncomfortable and space very small. Crew was excellent as usual.
It was a wonderful experience with great food, great staff, and no difficulties boarding!
I was in business class for the 8 hour flight where: 1. The WiFi did not work 2. The entertainment system did not work 3. We were told there were no hot drinks for the entire flight
Paid for “extra room” selected seat. Wasn’t a benefit. Also was in aisle and was bumped almost every time attendants walked down aisle. Should have saved the assigned seat money and let them select.
Alaska located my mother, aware that she had mobility issues and they seated her closer to the door. She and I were seated together so I felt more secure to be able to assist her. The desk attendant reviewed what steps to take when boarding. Allowed us to board first, we loved that. I was allowed time to help her board slowly, seat her, put all her things in their place before the crowds came through. These small details made me want to travel Alaska more when possible.
I bought the ticket through Iberian, but I was unable to check in using my code. American wouldn’t let me check in and Iberian counter was closed.
The comfort level was low, but the staff was nice
Bad. Requested a diabetic meal. Was served everything i couldnt eat. So i did not estbthe whole flight dinner / breakfast. Sad and uncomfortable.
Movies were old and third rate. Very poor on a seven hour flight. Food was OK but not business class caliber
Although the flight from JFK to Keflavik is not inexpensive, Iceland Air offers nothing but water, no soft drinks, to passengers without a charge. The seats are uncomfortable, there is no leg room, and there was no available internet to purchase.
Was hard to sleep, but other then that everything was good.
We got to the runway and had to go back to terminal to have plane worked on, which is fine, but the 40 minute connecting flight was already gone because of this delay and had to wait 5 hours to get on a different flight and only got a meal voucher which I didn’t see the email until after I had already ordered and paid for food. I feel I should be compensated.
Horrible. My dad was recently hospitalized and diagnosed with lymphoma and Icelandair refused to refund flight even though I had a letter from his physician.
Worst airline I’ve ever flown. Delayed 5.5 hrs, missed connecting flight, and missed an entire day of vacation. Zero customer service
Everything sucked. No food, one small glass of water, a tiny coffee, 5.5 hour delay with no customer service. Would never recommend flying them.
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.
Great crew, bumpy landings, two-hour wait for baggage with no communication or explanation. Will not fly again!
Decent service - nice seats. Crew were not overly attentive but can’t complain overall for the money
