Outstanding even though the 330 was one of the oldest in the fleet. The difference was the attentiveness and responsiveness of a really experienced flight attendant. For airline food great variety of interesting choices and good tastes supported by a good wine selection.

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Flight was on time, staff are friendly and helpful onboard.

Terrible last row seats many seats available but no offer to move to better seat

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Very good flight. Crew was great. No issues and we even arrived early.

The flights are constantly late anymore, and they won't even give you a glass of water on the plane. For years, they were able to do a service on this flight from Atlanta to Knoxville and Knoxville Atlanta now they say it's too short of a flight. You can't even get a quick drink of water.

Flight got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Great experience nice pilot very soft and easy landing and take off

We sat on the runway for over an hour before departure. That was unwelcome.

Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

It was Swiss. Our kosher meals were literally frozen solid and therefore inedible, and the crew didnt care.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

We used Kayak to reserve our tickets and specifically checked the luggage option which was a more expensive option. When we arrived at the terminal we had to pay an extra $90 per suitcase for the three passengers. This has been a pattern for the past 3 years. Why charge for a more expensive luggage option, and the ticket price not include luggage?

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Airline tickets are not cheap. You expect reliable competent service. Thanks to canceled flights and botched transfers we arrived at our destination two days late. This is not acceptable

I paid for our seats and when we boarded and went to our seats it was the last row. I would have never paid for my seats knowing I’m sitting in the last row. The airline must have moved our seats and I didn’t realize it when we checked in.

The crew was attentive and personable. The plane was clean and the seats comfortable. It was an excellent trip!

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

They cancelled our connecting flight resulting in another layover reaching our final destination 8 hours later than scheduled.

The Check-in process at CDG was confusing and the crew was not helpful. But the flight was on-time and that is most important to me.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

Screen didn't work, and neither did the button to tilt the seat even though the seat was comfortable

Second time with Saga Premium, everything was fab, but the entertainment centre on both my flights didn't work, plus the seat on the NY to Rek flight (Airbus) was so solid and so uncomfortable. The 737Max flight's seat was much, much better.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

Thanks to a delay of an hour of my flight to Philadelphia on American Airlines I missed my connecting flight to Amsterdam. On arrival at Philadelphia he crew on the delayed flight did not ask the passengers to let connecting passengers get off first and I arrived a few minutes after boarding was closed at the original time for the flight to AMS, this despite the fact that I had received a message from American Airlines that departure was delayed by 25 minutes. Overall very poor service, no effort from the part of American Airlines to accommodate the passenger, just rebook the flight for the next day.

It's hard to tell where to plug in electronics, and the port on my seat didn't work. Their entertainment system was down. Vegetarian food options were tasty. Friendly, helpful flight attendants.

Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

Lady next to me was coughing profusely the entire flight, other lady moved seats because of it, 8 hours of that during an overnight flight is a bit much.

The flight was ok. The seats are so small. The free wifi for members was not an option on this flight. The one flight attendant, older woman with straight white/grey hair, was very rude. The gentleman next to me asked about the wifi since he was a member as well. He stated, accurately, that the option to enter the idea number was not available. Her response was, "I don't know what to tell you" and walked away from him. The rest of the staff was wonderful. I asked another flight attendant about the wifi, she said the free wifi was not enabled on that flight (true or not- at least she was friendly). It was also pretty dirty. When I opened the tray table it had mushed crumbs and there was a dirty used pair of ear buds in my seat pocket. Lastly the air vent above my head was working but stuck so I was unable to move it to face me when it got warm. I fly American often but this really was not a great flight.

My luggage was lost at the airport but American Airlines contacted me and got it to me the next day.

Waiting area not big enough for all the passengers, no airport lounge.

24 hour delays aren’t even heard in 3rd world countries with archaic transportation systems. I’m never flying American Airlines again.

3.5 hr delay leaving Pittsburgh, notifications for which were incomplete and untimely. Connecting flight was automatically switched to one requiring more than a 30 hour layover! After waiting in a long queue, customer service reduced layover to 11 hours and also set up an earlier standby. The standby had empty seats, but the gate agent couldn't change our tickets! On top of all that my luggage was lost and has yet to even be located, much less returned 5 (FIVE!) days later. Too bad there's no rating below poor.

Canceled flight late London to Florence. Help at airport very poor. Treated poorly. Had to sleep in the airport. Lost bags- still do not have them. Horrible. I should be reimbursed!
