Very good- all went as planned. Flight was on time. Seating was a little sub , as always. Snacks and entertainment were basic. We arrived on time- no problems.

Katharine, Oct 2026

Rude staff from baggage check to gate crew. Poor instructions. Inconsistent application of baggage rules.

4.0 Mediocre

Christina, Oct 2026

There was an incredibly surly flight attendant that ruined the experience

8.0 Very good

Lisa, Oct 2026

Good but since we got in early we had to wait on runway for our gate. That was kind of a bummer but we still got in earlier than planned For entertainment I was watching a movie and getting close to the end of it with 15 min left but it kept jumping automatically to the next movie before finishing.

6.0 Okay

Delta seems to be getting worse. They are trying to take any comfort away from poorer people to make more money selling it to the rich. I paid for delta comfort and on my flight from Rome to jfk I had a tv that would go on and off automatically and literally no electrical outlets or usbs worked which was advertised in the price of the fare. The infotainment system wasn’t fully working. Luckily the movies worked and the plane was needing a lot of repairs. The jfk to Tampa flight they stuck me next to this really larger guy who was half in my seat and they should have made other accommodations for him because now you’re interfering with the fare class I paid for and act like I shouldn’t care because I didn’t pay for first class. I couldn’t even pull out my tray table because of this guy. The safety video tv screen you couldn’t even see it. It made me a little scared to fly delta anymore, because if these planes are this much in need of servicing, I have to wonder if the plane is going to make it to the destination.

8.0 Very good

Delayed departure, 30min. but arrived nearly on time. Crew was reassuring.

wifi never worked

8.0 Very good

Brett, Oct 2026

Connecting in Paris is always a wildcard, and this time was no different with the new EES system that people, including staff, don't really have a handle on. At least this connection didn't involve a bus, which has been a nightmare in the past. Boarding was a bit late, but once on the plane, flight was great. Very comfortable suites in business class. Service very good. Food was excellent. The Starlink WiFi was amazing. Worked well all the way from Paris to Atlanta.

8.0 Very good

Brett, Oct 2026

Pretty straightforward flight. Boarding was reasonable and the plane itself (a newer A220) was clean and comfortable. Catering was decent. WiFi not very good, but flight wasn't very long, so not a big deal.
