This was a short flight with no food. The attendants were great but the comfort was poor: just to cramped. The flight from Denver to Frankfort was excellent! Seating was roomier, food was good, service was good. This was a great experience.

The passenger in the row in front of me was listening to a political speech on his phone at full volume with no headphones and it was disturbing all of the passengers around him for several rows. I asked 2 of the flight attendants to speak to this passenger but they only shrugged. It was obvious that they were afraid there might be conflict and would not say anything. I had to take it upon myself to tell the passenger that he needed to turn it off or wear headphones as it was disturbing everyone around him not wearing their own headphones. I was very disappointed in the United flight attendants.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

We had selected seats in the app that were a 2x2 format in the middle of the plane. Our seats when we got on the plane had been moved to the back rows in a 3x1 format. What’s the point of paying up for tickets that allow seat selection if the airline will just change them?

I flew basic economy, so it was what I expected. Crew was nice though, and flight was quick. Would recommend for flights under 6 hours, otherwise would upgrade to something with more leg room.

We were traveling as a family of 5 and they refused to seat us together. There were entire rows open, and my 13 year old daughter had to sit alone. Ridiculous!

Bad, they delayed my flight, lost my connection flight had to stay overnight for the next flight and missed a lot of important meetings. 1 day totally lost!

I missed my flight and they would let me on the plane

flights were on time, boarding was easy. maybe better snack selection, like mini kind bars?.

There were issues with the first segment but what really bothered me overall is that you rebooked me and put me in a seat away from my wife and then put her in another booking or boarding group. I don't like having to monitor every little thing you guys do in order to get what I paid for in the first place.

No choice of meal in first class. Was the worst meal I’ve ever had in first class.

Experience was fine. Seats were cramped, and we had to wait for repairs before we could take of. Even though the door remained open, we were warned that leaving the plane could cause difficulty trying to fly out later. Staff was pleasant, and climate control was fortunately working. We had trouble at the DFW terminal, but I don't think that was AA's fault.

No complaints. Good WiFi, great crew and excellent speedy baggage claim

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

temp inside the plane was very hot and could not be adjusted.

The flight crew was fantastic! Which the seats had a small TV.

VERY disappointed at the agent checking in my luggage. I know that the weight limit is 23 kg, a little over 50 pounds (50.71 pounds). Yet the agent kept repeating "50 pounds". So I said, the limit is 23 kg, and she had the audacity to say 'no, it is 22 kg!" Imagine my surprise. Was she ignorant or was she poorly trained? Not sure. The boarding process was pretty good. The speakers were loud enough so I still could hear them despite inconsiderate passengers continuing to speak while the announcements were going on. During the flight, the teenage girl sitting behind me kept pressing her feet to the back of my chair. I turned around several times, yet she did not get the hint. I did not make a fuss since I sense I had a bad streak that night with AA, so I just did the best I can to lean forward and not let that bother me.

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.

There were several different delays but we ended up being delayed a total of 40 mins or so. It was annoying we had a gate change which made it take longer to leave DFW, and we had to check our carry on. Ugh

Terrible service three hour flight and they gave us a cookie… no TVs or screens you gotta watch from your personal device. The little flaps that hold your phone and stuff for storage or broken terrible experience

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.

Flight was delayed. They did a terrible job rebooking me. Agent on the ground was useless. The partner airline who ran the plane was able to help me but Iceland air was useless

We had to be bussed to the plane. And it was raining. Not a pleasant experience.

Late start due to so called cargo door, super expensive meals and baggage check( only airline where meals and baggage is charged on long international flights) slow baggage delivery at end a lot of employees at airport standing around talking to each other.

Good choices were awful. Crew was wonderful to me as I was disabled and they looked after me

Horrible. I was placed on standby for no reason and they would no allow me to fix the seating into the gate. Plane was hot. Entertainment was abysmal. Seats only take old USB or even older jack plugs — not lightening plugs like all modern phones. Food is pay as you go and awful. Seats were small and uncomfortable. I do not recommend Iceland air.

Great crew, bumpy landings and two hour wait for bags with no communication or explanation. Will not fly again!

Great crew, bumpy landings, two-hour wait for baggage with no communication or explanation. Will not fly again!

Seats did not have enough legroom. Reclined seat in front meant very little room to move. Tablet for movies was difficult to tap on. Food was excellent. Staff excellent.

Delayed flight with no explanations; no jetway boarding so we had to stand on the tarmac in the cold rain. Baggage was lost.

This flight went smoothly and the economy plus free upgrade worked very well.

Problems checking in. Charged for bag which was to be included. Repeated trials with in line check in process

The hot towels before the second meal was an unexpected surprise. The crew was attentive and personable, and that’s a lot on a nine hour flight. And the hot pretzels were a kind of “auf wiedersehn “ to Germany.

SEA to Munich flight was turbulent and you could hear rattling in the plane. The food was TERRIBLE, return flight was better. We will not fly Lufthansa in the future.

I had to fly United where the flight crew was atrocious

Sitting in a hotel in Chicago because I was rebooked due to a missed connection. Very frustrating.

Flight was delayed for no reason and I missed my connection. This added another day of travel and I missed an event I was traveling home for.

I missed my flight because previous flights came in late. Customer service hard to find and could not reschedule for the same day. Many people appeared to be behind the customer service counter, but only one or two willing to speak to the public. No offer to find alternatives My experience frustrating Very bad

Food and entertainment non existent as we were only in the air 25 mins so totally understandable

Everything was excellent except I could not check in online. The app kept denying me. So I checked in at the airport and the person was super polite and helpful. Very nice all around.

It was a great experience. I did find that some menu options were not available, which was a bit surprising, but over all a wonderful experience.

I wasn't able to request a special meal on the on line check in. I informed the cabin crew and they went out of their way to find foods I could eat. I am very grateful.

All went well- allow plenty of time at Heathrow, we felt like we got bused halfway to chicago when it was time to board, then had to carry baggage up steps outside. A bit of work for anyone who is less mobile or able bodied for sure.

It was a pathetic experience. Booked Hindu vegetarian meal and they served chicken. Inspite of telling them repeated times, the issue was not resolved.

I never was able to take this cancelled flight…all flights from Zagreb were cancelled at 3:30 AM of departure day 9/8!

Friendly crew members. Food was so-so, below average. However, ice cream add a little touch and made a difference.

Overall American Airlines are good. For a long haul flight I would have appreciated if they had offered water durning the flight, as they don't provide individual water bottles. I applaud their recycling efforts onboard.

Experience was probably the best I’ve had on BA for a long time. Only thing is A380 is old now and it needs upgrading. The en re attainment screens are very small and the touchscreen barely works.
