Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

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.

Excellent service, I love the soft blush pink mood lighting on the 767-400ER during meal service. The overhead gasper vents on the 767-400ER were also very strong with a lot of airflow to keep me comfortable on my flight.

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.

No meal service to the back of the plane as it started late or was too slow to get it out before it was time to land.

Terrible, if possible won't be flying again anytime soon!

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.

The business class seat is exceptional. I wish the food is more palatable.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

the entire flight felt off. The crew seemed uninterested and disengaged. The food service was really bad - overcooked, bland, weird food service. They actually woke us up to serve chicken wraps in the middle of the night, after dinner and before breakfast. Made no sense. Ultimately, I was glad they did though, because the breakfast had been held for so long it was inedible. Eggs, potatoes, sausage - all disgusting. We were asked to "honor" the lavatories for premium customers and stay in our own cabin: this was also strange. So people in economy didn't pay enough to use the closest toilet to them??? It's a toilet. All in all, not the experience I have come to expect from United Airlines. The return flight from Paris to SFO was better, btw.

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)

Overall, the flight was good. Lounge access should be with all business class tickets.

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.
