They canceled our flight and left us stranded to figure it out

We appreciated the friendly, efficient, and professional flight attendants. A wider selection of hot foods would be nice.

Did not have enough time from Venice seaport at Ravenna to get to Venice airport in order to make the scheduled flights. Need to have at least 3+ hours from ship docking to airport.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

The plane used to go to Chicago was a bit outdated and needed a refresh

My connecting gate in .Chicago was across the aisle from my arriving gate. Otherwise I would not have made my connection. So that was very fortunate.

when you can say you don't remember being at any point upset during a flight, the airline is winning .

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

Fantastic. I am low vision and was impressed with how helpful and accommodating the service tam was. It was super appreciated! I was pleasantly surprised about how delicious the food was. Like, “I wish I had more even though I’m no longer hungry” delicious. 100% enjoyable trip.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

Flights were on time both ways, such a big plus! Staff was very accommodating and friendly. Question the choice of snacks that, which on both flights was dairy based. Appreciated using bottled water.

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

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 flight was on time and the crew was nice. I did not like the fact that my husband and I were seated in different rows. I feel pressured by airlines to pay more to choose our seats. We will sit anywhere, but we shouldn't have to pay to sit together. I also think they should serve at least a snack that's free.

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.

My only area of issue was the flight was rather warm and the knobs for cool air didn't allow much cool air to come through. Everything else was great.

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!!

Good, but I feel there should be a separate boarding line for seniors

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

Plane left an hour late and missed our connecting flight. Your service center was closed ao Alaska Airlines could not change the ticket. Thus we missed the chance to get out that night to San Jose. This is a major operational blunder.

Well! They got me as far as Iceland, let me wait around at the airport since my next flight had either left or canceled, finally gave me my luggage, and sent me to wait quite some time with seven other people for a ride to a hotel. At the hotel we got a chef's salad, a nice room for the night which unfortunately had feather pillows and duvet (allergies), a really great and spectacular buffet for breakfast (small but stunning), taxis back to the airport for the 9:30 Delta flight back to Minneapolis. The Delta flight has free food and liquor included which Icelandair does not. All in all, it falls far short of my worst ever United flight to SGN. Icelandair did change my reservation after my roommate tested positive for COVID and we canceled our plans to travel around Iceland, but the charges were fairly hefty. I had trouble contact Kayak's agents to discuss changing my reservations and finally contacted Icelandair who changed them. (I used their contact form and put in several requests for call backs.) Of course, they called just after I made the change with Icelandair.

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

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

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

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.

Flight was great. Had to wait almost 100 minutes for luggage (some problem in the delivery). This may not be an Aer Lingus problem, but an SFO problem.

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!

Flight was fine, food better than anticipated and flight attendants were helpful and friendly.

Our headphone plug is broken, we can not enjoy our entertainment, especially traveling with 5 year old who like to watch movie

It was good but I wished if they could have sign do not disturb if we did not wanted any meals . I was tired and slept through the entire flight and woke up just before landing .being hungry Too late to ask for something to eat before exiting the flight . Left feeling hunger 🙁

Pleasant, attentive and efficient flight attendants. Boarding process and seat selection easy. No internet on transatlantic flight. Extremely uncomfortable, rigid seat.

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

I was disappointed with the quality of the food for an international flight also I wasn't given a toiletry bag which is customary in international flights.

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.

Boarding is not controlled as groups called was not enforced
