The flight was delayed 90 minutes The Gate was wrong The Restroom on Aircraft was not clean There was a half used water bottle in my seat

Delta is always a wonderful experience. A clean plane and the crew is really friendly.

Too many people are taking up space in the overhead bins with their extra piece of luggage. Since they cannot fit their backpacks or extra luggage piece under the seat in front of them, they store it in the overheads and thus taking up room for other passengers. It wasn’t only one or two persons; more like 12 or 13 passengers.

This was the worse experience. They delayed our flight twice and we still had to find another flight to get home sooner which was alos delayed. Also, the flight attendant named Ginny on DL9890 leaving at 4:13pm on 3/23/26 was extremely rude.

I love Delta the flight attendants were personable and the flight arrived 1/2 earlier thanks expected. All a plus. The gate agent was a bit flustered but even with that I still had a good experience. Her supervisor assisted me.

Got to fly my favorite plane, the Boeing 767-400ER, to Milan. The soft blush pink mood lighting during meal service was very beautiful and gorgeous. The service was top-notch, and our flights were on time. I highly recommend Delta.

I am still at the Airport! Delayed Delayed and Delyaed

I took seat 15A in anticipation of window seat, there is no window.

The first class flight attendant was awful to everyone. Very rude; no customer service. She should not be working in first class.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

They promise free wi-fi prior to boarding and then once on board you are informed you have to purchase wifi even after being a mileagePlus member.

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

Awful. No counter attendants. No dinner offered due to delays.

Horrible service no Wi-Fi connection on both leg of the flight and they are refusing to fix bad service

3 hour delay…. Nearly 2 hours sitting on tarmac. Do better, United. Or at least have the sense to not say “we hope you enjoyed your flight with us” upon disembarking.

Flights were on time. Free Wifi on plane. Everything was well organized.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

They delayed the flight from 9:00 to 11:55 At 11:45 they canceled the flight. I paid a premium price for the tickets with poor service

We had excellent customer service despite the chaos at George Bush airport in Houston!
