Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Delta is one of the best airlines I have flown

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

no issues at all... Kudos to the food. This time was really really good

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

Good with British Airways - terrible with American Airlines! Stood at gate for “mechanical problem” - plane delayed. Had to check my personal belonging with 5 empty bins available in plane, desk staff rude!!! Toilet not working- asked “to use working toilet sparingly - it may overflow in cabin!”

Paid for premium economy had no tv the whole time the crew tried to reset/reboot but would not work they said they would put a trouble ticket in for it. We had 3 seats my tv was the only one that didn't work. They cancelled our flight re worked us on another that left us at airport over night on the floor I have a ten year old and a 78 diabetic mother which also had shingles and suffers from nerve pain in legs and back. Requested wheelchair service at all airports after the re route NO wheelchair service was there to help. WORST experience we have ever had. Went to American airlines assistance it was closed. I AM FURIOUS!!! I expect some sort of compensation from this traumatic experience and no need for flying points we don't plan on using American airlines again!!!!

The flight was sequentially delayed until it reached two hours. Apparently one pilot failed to show up.

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

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."

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.

Boarding was as fast and efficient as possible. The flight crew were amazing and extremely friendly. We enjoyed our flight.

There was nothing to like besides the crew. The comfort of the airplane was poor (seat did not work properly and it was not comfortable). The “entertainment” system did not work! On a flight that last nearly eight hours, (which is advertised as having excellent entertainment options), that is unacceptable! Passengers should have been given free WiFi for the flight. The food served on the flight was below school lunch grade food. (With one exception, the ice cream snack). The chicken entree was tough and nearly impossible to cut and eat. The “pizza” served later in the flight was worse. The chicken pizza had a dry crust and the “toppings” were equally not enjoyable. The amount of chicken and cheese were almost non existent. Overall not a flight we would want to repeat!!

There was a problem in the luggage because there were not porters

2-1/2 hours on tarmac after arrival to DFW, lost connection to London, 3 hours wait for customer assistance, stayed on our own account in DFW, no replacement flight for 5 days, had to cancel the entire travel and return to Monterrey today.

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.
