I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

The IFE was quite old, but it worked fine and the content was good. The cabin crew were excellent and the food was as also very good

Great flight because I upgraded to Premium Comfort. Made a huge difference in the experience.

Good experience, just i couldn’t connect me to the wifi

Was trying to change a flight but told that Canadian and local klm systems do not interact so they could not access my booking. Overall I like klm a lot but if it was important to change flights I would be very frustrated.

Flight was delayed. Can happen. But the info on the website and app said that flight was cancelled which was not the case.

KLM is my favourite airline. Never ever let us down.Staff are first class.

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

Flight delayed over 2 hours . I was flying bussiness never got food cause they ran out of what i wanted

Flight was great my baggage was on time everywhere but my bags had been handled ruff cause they got damaged.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

Poor and identical to the first two legs, except for the crew who were patient, professional and of pleasant and jovial disposition!

The entertainment would not work. The comfort of the seats leaves something to be desired, pretty uncomfortable.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

Short flying. The seats do not recline at all and very uncomfortable.

Delayed over an hour due to paperwork not being filed correctly. Forced to change planes.

Packed commercial flight was as comfortable as can be expected

I'm not a valued flyer so I'm always in the last group to board...that sucks, always

boarding was quick and painless. entertainment could have been better- but that's also what ipads are for.

Domestic airlines have really fallen from what they used to be.

Overall good. Tight connection in DFW because of gate unavailability upon landing.

A very good flight. All personnel were gracious and pleasant. Good flight. No complaints.

horrible our connectig flight was late and we had to rush thru DFW to the next gate with 15 minutes time. Get to gate and its changed. no one knows whats going on . finally get a new gate and the plane has been sent back to the hanger . Boarded 4 hours after our original flight time and then sat at the gate for over an hour as the captian said the cargo doors were open and no one was in the airprot or on the ground to find out what was happening. this caused us to miss the first day of the tour as we missed our transfer and hotel meetup no apologies or accomodations offered to assist

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

Flight delayed from rdu due to too much fuel. Had to stay overnight in dfw. Food vouchers inadequate to cover dinner and breakfast

I missed my connecting flight despite requesting a wheelchair and had to wait at the airport for an additional four hours

The connection required us to travel from terminal A to terminal E with very little time in between flights. While waiting in line, we were called to the service desk to provide our passports. We provided our passports at time of check in, assuming that American Airlines doesn’t communicate well with Iberia, this was a headache.

The staff on our flight from Charlotte to Boston were very friendly.

Alaska located my mother, aware that she had mobility issues and they seated her closer to the door. She and I were seated together so I felt more secure to be able to assist her. The desk attendant reviewed what steps to take when boarding. Allowed us to board first, we loved that. I was allowed time to help her board slowly, seat her, put all her things in their place before the crowds came through. These small details made me want to travel Alaska more when possible.

HORRIBLE. 3 hours delayed. Crew did not communicate properly and was rude to passengers enquiring. Delay caused multiple passengers to miss connections.

1. The flight was late and I did jot get the seat I paid for. I paid for extra leg room and a window seat. I got a middle seat without extra leg room. 2. The customer service representative was not helpful. Explanation: many passengers arrived to the service desk in Madrid near baggage claim to rebook our flights. (We all missed our connecting flight due to delays in JFK). Upon arrival, ghere was one service agent and one line-business. After about 25-30 minutes the agent left and we could see her making a phone call. After about 5 more minutes, 2 other agents arrived. During our wait, another line formed for main cabin customers. We were told to go to the other line, even after waiting around 30-40 minutes. This would have been disastrous for ghose of us who had been waiting for so long. The agents need more training.

I fly to BNA with BA often and this was the worst experience. Arriving in nashville, check in was 1.5 hrs long in the queue with 1 very slow girl at the desk. When more staff came they only catered to priority customers. When all priority were checked in, instead of filtering from the top of the line they took the people from the end, the people who had been queuing for 5 mins vs almost 2 hours. The flight was delayed, for no good reason other than the staff took forever to do anything. At the gate there was zero organisation, we asked the crew what the delay was and they confirmed it wasn't the plane and it was the ground team. One of the flight attendants was one of the rudest I have EVER encountered, that man clearly hated his job, and people...I wish I'd got his name. Food was disgusting, seating was cramped. I've no idea what's changed in the last year but I'm truly shocked.

Booked Economy Premium the 3 seats with my daughters and I, the seats should have been able to tilt back but it only one worked. the crew said they would report it but didnt seem both about our comfort on the return journey.#

Better pillow cases in economy. I didn’t like that I couldn’t pick my seats since I booked with Kayak.

Room between seats unacceptable. If person front of you dropped down there seat even a little you could not be even a little comfortable. No sleep on flight

I am very happy always when I fly with Iberia.
