Great overall experience and use of the Delta One lounge was amazing!

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Great as one can be for a one connection 6 hour flight

The gate attendant was not clear w message on flight delays.

Chairs don’t recline and the ones that do recline, barely do recline. It was most uncomfortable flight i ever been on.

Good service but not on par when compared to foreign flag carriers.

Travelling with 2 others for work. Delta asked to check their carry ons due to the fullness of the plane. This was all good until the next leg of the flight. One of the 3 had their carry on checked through to the final destination but their passport on in their checked bag. Which they could not get to and he was not allowed on to the plane. Even though Delta had to retrieve his bag, because he was not allowed on. So they got his bag and he was in the terminal, but even when the flight was delayed, due to mechanical issues, he was not allowed to come onto the plane. Since the delay was nearly 2 hours, he was finally allowed back on the plane.

good in general food is just snack and beverages (same snacks all the time) could you try to change them?

We experienced delays in small increments that added up to more than an hour. At the gate, staff showed little concern and compared our delay with the inbound flight’s two-hour tarmac wait, which didn’t address our situation. Once onboard, the flight attendants seemed tired and unfriendly. I understand delays are frustrating for everyone, but passengers shouldn’t feel blamed for them. During the flight, a bright light above the emergency exit stayed on. It was concerning, and no one explained it or offered passengers the option to move. After landing, we waited about 30 minutes on the tarmac for a gate, then waited again for an agent to connect the plane to the terminal. From the Reagan gate staff to the cabin crew and RDU personnel, the service felt dismissive throughout. Overall, this was a stressful trip and a very disappointing customer-service experience

The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.

The staff on the flight were utterly brilliant; there was a young man who was particularly exceptional. Boarding was quick and seamless, and service was great! Seats were fab, as was the entertainment and its ease of access

i’m The staff on my flight were amazing as always, beautiful professional staff, they do amazing job. the food ? room for improvement

The agents at the boarding desk were not very helpful, however the hostesses on board the flight were great, the food was ok, and there were lots for choices for entertainment. I was stuck in an middle row seat which was a pain on a full flight, but otherwise the flight was great.

The man in front of me reclined the entire flight, including during meals, which was aggravating. My screen had issues with brightness and kept flickering in and out.

Still some confusion about my baggage which was disconcerting. It was nice that there was extra space on the flight for comfort reasons. Staff very friendly

Overall good. We weren't able to find out about food options for the flight and there was nothing I could eat due to allergies. The biggest problem was getting our checked bag at Logan. Waited an hour!

I loved both of my flights to Ireland and back to Boston. The only negative was it took over an hour for the baggage to be delivered.

Economy seats a bit small but other than that it was all good.

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

Loved the easy process to board and the experience overall was smooth

Set on the plane for two hours before pushing off the gate due to the power source issue being fixed which was known before letting people board the plane. On top of that it was very hot as AC was not working properly. Terrible experience and limited communication provided by the crew on the status of the issue. They should let people deplane while issue is addressed instead of frying them and glued to the seats.

I am United’s newest fan. The planes are clean, the staff is so friendly and snacks are more than just old pretzel crumbles. The captain came and said hello! Truly amazing experience

1 person checking us as we boarded, left gate on time, 12.30 we are told we were held for 15 mins as other flights were waiting to take off, captain due to rain … they were having a longer gap between take offs , 3pm we took off , they went land route via New Orleans in to Florida landed at 5.45pm offered coffee and a biscuit

Service was slow Flight was very loud at back of plane

There was no internet on the flight. As an executive flying during prime business hours, having internet is critical for a smooth experience. This impacted productivity and time that will need to be spent later to do the work I could have done on flight.

Terrible boarding - 4 flights boarded from the same gate. Chaos there; long ramps to the plane.

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

If other people in flight, followed instructions and were much cleaner.
