Everything about this flight was good except for the very end when I reached my destination. Everyone from the tune to the wheelchair escorts were great with the case were great but I miss you with people at the check in this at the very end. I need help from the chicken desk because I forgot my pillow on the plane The female worker at the chicken desk said that they found my pillow and she was going to retrieve it for me. She left a 30 minutes without any update and her so she saw me walking back and forth waiting for her and they didn't even bother calling her or radioing her for any updates. They were busy because they were behind schedule and they were overwhelmed but thanks because at least glanced me and try to give me an update just a quick radio check or phone call. I don't care about the pillow but if you tell me to wait, I waited for at least half an hour before I said something and I just left because they wouldn't bother talking to me so I could, so everything's going in the review. I took pictures of the two men that were left working at the check-in counter. The totally ignored me despite the signals I've been giving them. I don't see any offers in the kayak review to add pictures or screenshots so I'm going to post another review I don't know their name but I'm pretty sure Delta will find other names when they see the review. Google with pictures. There was another guy at the chicken counter bring an orange workers vest who finally left after telling me that the girl that was retrieving my pillow is working the gates now. That would have been if they just told me that's what happened. But I had no update. Make me wait for nothing. Thank you Delta airlines!

We had a great experience with Delta. They helped us from the start at the kiosk all the way to our final destination, including help reassigning and upgrading our seats free of charge at the gates, escorts with the wheelchair for my brother and even getting our luggage at baggage claim for us. I also had special help because I forgot my pillow on the plane. The wheelchair escort contacted for associates at the check-in desk all the way back to the plane and retrieved my pillow for me.

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

Was charged for my luggage despite having been on one ticket from an international flight. Too tired to argue after 15 hours on flight. Was charged for rechecking it at JFK airport. Not sure why those off Kenya Airways were required to do that.

The checkpoint hornets are always looking fhrough Americans' luggage keeping what they deem impassible! Grrrrr!

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Not pleasant. We arrived several hours late and my friend and driver were waiting for me a long time at Tucson airport. At first we had to divert to phoenix due to shitty weather. Well, i guess I can’t fault anyone for that. But then when they refueled , they overfueled and we had to wait even longer for the plane to burn off excess fuel. So someone really screwed up there and should get fired. Human error is really inexcusable.

Everything was great except for the seat. The backrest would not stay in the upright position.

Didn’t make the flight. My connecting flight was an hour late and I missed the flight. You rerouted me thru Atlanta and I arrived in Rome over 10 hour after my original Rome arrival time. You also left my luggage in Atlanta and it took you three day to get my bag to meI spent 4 days in the same cloths, I had packed my prescriptions in the lost bag and went 3 days withoutMy heart meds.

A220 brakes are grabby and uncomfortable Electric braking is not a good solution for a modern aircraft

I liked the snacks and the flight attendants were friendly.

Other than a way way too cold cabinets for the entire flight, all was great

Absolute disaster. Rude, uncooperative staff. Staff ignores and pretends you don’t exist when you are asking them a question. Erroneous departure gate and baggage claim information. Equipment not working for purchase of drinks. Overly expensive baggage check-in fees. Overly crowded. Dirty airplane. Passengers coughing incessantly as if they were being gassed. Circled airport in flight several times and waited on the tarmac for 1.5 hours. The worst experience ever. Consider another industry. The travel industry is not for you.

The flight was mostly on time, smooth and deplaning was quick. Baggage was really quick at the claim. Comfort was so-so and I paid for economy plus. It was still too crowded and why was a family of 5 scattered all around the plane?

Original plane sidelined. Had to wait an hour for replacement.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

The flight experience was very good! Especially the United Club!

The flight from Ottawa to Chicago took a lot longer due to DC in Ottawa. We got to Chicago and went to our gate to catch our flight. We only had nine minutes I found that very stressful.

Boarding crew at the gate were hilarious and made boarding run.
