Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

I was sitting at comfort +. One of the Asian male crew was so loud when he delivered service. When he asked questions or what food you need, he was shouting. He must be a prison guard before going Delta.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Space and comfort was good. Staff could have been more helpful and friendly.

Crew was not friendly when I went to request a seat change.

Really impressive staff at airport and on plane, especially given how busy it was

Was a great smooth flight from Detroit to San Diego.

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

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.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

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

It was nice to be on a legacy airline, people try at least.

At the transit could be less time not like 12 hour 6 hours the mix should be 4 hour, thanks

Everything in general was great, but we left 30 minutes late

Pros: "Seats were very comfortable. Plane interior was in new condition, including electronic window shade tinting."
Cons: "Staff was not particularly warm or attentive. Was never offered more to drink, and after asking for more wine was ignored."
Cons: "KLM lost my suitcase and did not deliver it until three days later... They refused to compensate me for having delivered the bag with broken articles inside (A pair of Rayban Wayfarers!)"
Pros: "The best airline ever! Super friendly crew and staff, great customer service and nice planes. Love KLM!"
Pros: "Due to business I travel allot so I deal with allot of airlines. This is by far the best airlines I have used. Excellent crew and airport staff. I don’t think words can express how satisfied I am with this airlines and airport. The nicest people and great service. Clean and modern aircraft. Going to try flying only with KLM from now on."
Cons: "Nothing"

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

Over two hours wait to get wheelchair assistance from arrival to the departure gate for LA was unreasonable even though there appreared to be heavy demand.

The seat is too hard and my back and bottom are having servers pain

I was duped into thinking it was a United Airlines flight when in fact United had nothing to do with it.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊

There was no lounge for passengers waiting before boarding the aircraft at F65, so passengers are just sitting on the floor or just spread everywhere the premises before boarding.

All went fine. Boarding was efficient, staff was really friendly, and we were kept up to date on any changes to our itinerary. My only note for improvement is that on this particular plane, the recline in economy class was negligible. I know it's a coach seat, but I had another UA flight (SFO to BWI) and the seat was more comfortable with better recline.

Really good experience with a redeye flight from SFO to BWI. Boarding was efficient, plane was comfortable and newer than others, lots of audio and video choices, and staff was great. I appreciate United's service.

The flight and crew were fine. The entertainment- the sound was so bad through the headphones I could barely understand it and it was a show I had seen before. The food might have been fine but having to have an account with united in order to access the app in order to pay for the food was rage inducing. I had entered my credit card info at home and logged in as guest but that wouldn’t allow the “wallet” tab to open in the app. And then the wifi was so bad that it took about 45 minutes to fully log in and get all the info working at which time I missed the food. You shouldn’t have to give your address, email and phone number in order to get a hamburger.

The crew on this flight were excellent. They were friendly and attentive. It really made the flight more enjoyable.

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.

Boarding process needs to be improved. Business class passengers were told to stand in the economy line and vice versa.

I travelled on biz class and f there is no water in the toilette to wash my hands I would expect to have this indicated somehow and not just finding out when I'm there expecting to be able to wash my hands and teeth. Also this is in general that it is always so rushy at the end of these kind of long flights. It is like we are sitting there for 9 hours and the last 1.5 hours just feels like I have time for nothing. Because food comes and at the same time we are close to destination everyone tries to pack their stuff and go to toilette and eat and everything :))) not that like I would know a good solution here I just wanted to raise this :)

Emergency row seat less comfortable than promoted. Restricted by emergency life raft storage.

Better communication to those connecting flights and have a customer care desk at the airports

American was good / British Airways partner was not as good…

The entertainment system in our row was not working. That makes for a VERY long flight!!

A little more legroom, and maybe a little bit of food

Pre flight food options were not working and made the flight not enjoyable. Post experiences of British airways have been positive, but this is enough to stop me using British airways again
