Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

For some reason, I couldn't choose my seat. The airline gave me a seat when I got there. Not happy about that. Otherwise, everything else was great!

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

Staff on board was excellent. Positive upbeat helpful- like it used to be.

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

Even though we were delayed, we were able to make our connection

Crew and customer service were excellent. This flight also had plenty of leg room and seat mounted screens for entertainment. A very pleasant flight all around!

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

I flew with my dog and had already purchased my dog’s ticket. Even that morning I had called costumer service to insure that my husband and I had seats together since the website was giving me an error when choosing our seats and the representative mentioned our dog. I showed up early to the airport and when I got to the gate and we started boarding I was help back and told that I was supposed to have a yellow tag and that I should have checked in at the counter for them to give me that tag. I was not aware of this, the representative on the phone did not say anything. Nor did I see it anywhere in the checking process online, so if you travel with a pet and are not checking in luggage, just know that you still have to go to the check in counter when arriving at the airport unless you want to be the last one to board and not have room for your carry on in the overhead bins. Other than that, I had a great experience.

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

A more organized boarding experience and better food would have made the experience better.

why can't planes be boarded from back to front?? everything was great otherwise

We flew into Barcelona and the plane was so cramped and very uncomfortable and dirty. But we flew out of Madrid and that plane was much better. Would fly Iberia again.

For what we are willing to pay for international air travel, our experience was very good. We had no problem checking in, we had very little wait time at the AA counter in Madrid, and the staff in Madrid were very helpful. The flight crew was helpful and courteous, the plane was on the newer side, and our assigned seats were together without us needing to purchase them. The flight took off on time and arrived early. Overall, it was a pleasant experience or as much as could be expected in economy for almost 10 hours.

Boarding was easy, the flight left on time and even landed 20 minutes early. The food was plentiful and really good! The crew was kind & helpful. Overall it was an exceptional experience!

We were delayed 2 hours because the crew was late. They need better planning by the crew, we had to sit in uncomfortable seats waiting for them.

The flight was safe, confortable and convenient. Thank you. I hope to come back soon!

temperature was too cold there should be free blankets, seat are very uncomfortable, entertainment is limited.

Basic service for a decent price, all amenities are à la cart

The plane needs upgrading, the seats are uncomfortable, we are a family of three and they split us and did nothing to group us together, and the food is horrible compared to other airlines bu
