Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.

Non stop on long haul is the way to go. Great experience

Seats comfortable, service and food very mediocre, staff not very attentive, worse than many other our flights with Delta.

Overall good experience; however, there was one flight attendant who was rather rough compared to everyone else. Everything else was good: entertainment, food. Delta keeps on delivering! Thank you!

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

Crew blocked exits to front of ship with galley carts. Also split five person family apart on international flight without fixing.

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

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.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

This is for UA2274 from Houston to Sacramento. The flight was delayed arriving due to mechanical issues so we left about 3 hours later than scheduled. When boarding the plane the temperature inside was excessive - likely close to 100. Pilot apologized and said it was going to improve at altitude, which it did. But before that I honestly thought there might have been more delays removing passengers made ill from the heat. We were delayed leaving due to another mechanical issue. There was not water on the plane due to a panel that was not secured. They did that quickly, but the combination of mechanical issues was rather disturbing and did not reflect well on United.

United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.

The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.

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

Horrible almost missed my flight because my 1st flight was delayed. Airline crew is so unprofessional. The people on the plane do whatever they want kids running screaming. Will never fly this airline again Suitcases never arrived
