It was a crowded flight. They did the best they could.

It was a crowded flight. They did the best they could.

Service was good for such a short flight. Small plane but smooth flight.

Worst flight in my life. Only was scheduled for a 45 min flight to get our connection flight. It was late by 40 minutes and we missed our connection. Delta was totally useless trying to help and unable to get my family on the next flight because they overbooked it Thus had to get a hotel at my expense and lost a day at Disney as a result. Cost me about a $1000 if you add 2 hotels meals shuttles etc to get thru the day Awful customer service by Delta in Detroit totally useless people

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

Boarding was great. The flight landed early. It took the crew over an hour and a half to bring out drinks. I paid to upgrade my seat to Comfort+ only to be near a crying/screaming baby who was seldom quiet. Noise-cancelling earbuds didn’t even help. Waste of money to upgrade.

Seats in first class on the E175 recline too far back. I was in 2A, and the man in 1A fully reclined almost the entire flight. It took 6-7 inches of space away from me and made it very difficult to work on my laptop.

On 2 different flights the wifi was horrible and there was no drink or snack service.

Wifi wasn’t working well so we couldn't view any media.

Flight was late. Club was full. Experience is exactly what I expected.

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

they made me check my carryon. There was space in the overhead bins.

Nice flight, nice crew but no cookie or napkin with my seltzer.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

I liked everything about the flight. The service was excellent!

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

Flight from SBP to DFW 1. They rerouted us through PHX 2. Delayed flight out of SBP for 3 hrs so we missed our connection Downgrade on rerouted flight. Back of the plane, center seats, didn't sit together 4. Return flight out of DFW same exact thing. Delayed, missed connection, Downgrade + they lost our luggage! A complete mess.

On the new 319 NEO? seatback entertainment system did not work even when the flight attendant rebooted it. At least I had my cell phone to connect with wifi.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Do not eat the bagel! Otherwise, good albeit late, breakfast in first. Boarding downgrade only because flight was delayed due to plane change due to undisclosed problem with original aircraft. I did not use entertainment.

Because I can’t stand very long in one place, I was allowed to reword.

It was a good flight. Of course it was full, but it went well.

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

The flight was fine. All the delays and poor communication and customer service were the worst! We were supposed to arrive in London at 7:10 am. In stead we arrived at 1:30 pm. And now American Airlines refuses to make things right but only sent a canned apology after I contacted customer relations.

Horrible people at the gate, they force me to check in my carry on, even thought no one behind me has to do it. I had to get out of the airport in NY to get my bag and go thru security again on my way to Honk Kong. The worst part is the employee threatened me with loosing the flights if don’t comply.
