American Airlines actually put me on a Delta flight. They didn't have to do that. They could have offered me a flight the next day or even two days later. But, American Airlines agents put me on a Delta airplane from Atlanta to Sao Paulo, instead of going through Miami when my flight to Miami was cancelled. American Airlines made sure that I got to my destination on time. I appreciate that.

It is the worst service I have ever found in Business Class in 39 years of traveling. The guy in the area was not qualified to work as a flight attendant. Dress, attitude and delivery was inadequate.

Unfriendly gate staff and significant delay once we were on the plane.

The gate crew did try to help, however they lacked the information as to whether the flight will operate or not. Being delayed 6 hours and in a limbo on whether the flight will operate or not is not fun. The airline having staffing issues is not encouraging at all.

Multiple gate changes and significant delay leaving DFW. Made for a late arrival

The flight from DFW to chs was delayed with multiple gate changes.

Our flight was delayed by 18 hours. Poor accommodations made and no apology.

From check-in staff to in-flight staff, everyone was wonderfully kind

What an idiot at the boarding gate. Even flying First she was mean and unpleasant.

I missed this flight due to delays on my previous flight.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

Short flight so not much to rate. Surprised I had to pay for a soda.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats are better cushioned then some

If you are looking for the bare bones in an airline - this will do. The boarding process in Newark and Iceland was so disorganized, I thought there was some sort of emergency. No - this is what they do every time. After a full plane was ready to board in Newark, Icelandic Air insisted that everyone have a paper ticket in hand. Mass chaos ensued as dozens of passengers then had to line up in a different queue. On the 5-hour flight, two tiny glasses of water were dispensed. Yes - I could have ordered food, but not even a pretzel was given for free. In Iceland, a full plane of people waited over twenty minutes in a cattle shoot hallway while the plane was readied. Why were we lined up so early? Kids were screaming and some older adults could not stand for that length of time and also hold luggage. Flight was pleasant with the same two glasses of water -one in a tiny paper cup. Movie selection decent but headphones will cost you $5.00. What airline does that? Charge me five dollars more and give them out to passengers. Shame on you for being so cheap!

So Iceland Air is one step above Spirit Airlines. They do not feed you unless you pay for it or are in Saga Class. So, bring your food. They have a drink service, but it's in a large Dixie cup. Ask for the can, that is the only way you'll get a real drink. Also, we missed our connecting flight so they put us up in a flea-bag motel. Don't get me wrong, the staff was nice and friendly, however, there was no shower gel or shampoo in the hotel. We have to go to the corner store to pick some up. The room was not in great shape. Holes in the bathroom, a badly repaired ceiling in the room. The window was warn out. So, you get the just of how bad it was.

Food and staff were excellent. Seats on Saga (business class) are comparable to domestic first class of US Airlines, regarding space and recline. Entertainment options had little international component.

Flight delayed Delay to the gate upon arrival Baggage took more than an hour so we missed our connecting!!! Terrible experience!

There is no food without paying $. Only soft drinks are included in your fare.

Some drinks and basic snack will be good. Water should be served at least once an hour. Blankets for folks who might be cold.

Pros: "Flight was relatively empty. Professional crew, comfortable seats"
Cons: "I think they skipped me with food service. Checking up on passengers who may have been sleeping would be nice. Headphones need to be purchased. Limited entertainment options."
Cons: "Communication about international COVID requirements before the day of departure."
Pros: "My seat cushion was out of alignment so not great. But I like the two side seat configuration."
Cons: "Boarding is a zoo. Board by row. It’s faster."
Pros: "Icelandair crew were very hospitable and accompodating"
Cons: "I have never sat in such a narrow seat. Literally could not put my hand down the side to pull out my seat belt. Two days later I still have sores from where the side of the seats hit my hips. Did not even provide complimentary peanuts."

Boarding was relatively smooth considering we were in Group 7. This was not a full flight so it went a little quicker than expected. We were on a 787 which is a wonderful plane, it felt like we had a little more legroom flying economy. The auto-dimming windows were a pretty cool feature. The flight crew were amazing, very attentive and they served a ton of food, snacks and drinks. I was surprised at how much we got. The flight went smoothly and we had no issues. I would fly overseas on AA/British Airways again.

Horrible experience, flight was delayed for 3 hours due to insufficient crew and tray was broken. Seats were extra tight for international flight and food was horrible

They could do everything better!! From the rickety plane, to the flight attendants… when American Airlines is operated by British Airways, their standards are lowered! It’s like Macy’s, operated by Walmart!

The lack of leg room for a 6 foot person makes for an extremely uncomfortable flight over the pond. Short little puddle jumper from Paris to London and back no big deal, but nine hours in a tiny and unbelievably hard seat makes me not want to do that ever again. This is my third trip to Normandy. FYI.

Every host and pilot were very professional. My next flight would be upgraded from economy to the next group.

I asked for a window seat and when I got on the plane 24A did not have a window so was very not happy, but good and entertainment was good and the staff was very good, so the only complaint was the seating.

Flights were actually with Aer Lingus outward and American Airlines & Aer Lingus on the return journey. Outward flight with Aer Lingus was good but the return flight with them was not so good as our seats were in a poor condition (15A & 15C) and looked like they needed replacing! The American Airlines flight from Miami to JFK New York was good and the seats were very comfortable and spacious (32D & 32E)

Awful. Flight delayed and we missed our long flight to Rome. It has been a nightmare and we have still not arrived. It was NOT a weather delay, just poor planning by AA

My seat was in a good row. In our section it was the first row. But it was difficult tooperate seat entertainment features > table, screen, even though I often fly.

Lost bag on an hour and a half flight with no connections - ridiculous!
