Flight attendants were great. Cheerful, upbeat and friendly. Jet, in particular, was fantastic.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

Flight delayed four separate times. I’m now one hour hours late to landing.

worst flight ever from Delta, it got delayed and kept on delaying..

Should never have had to go to Detroit from Orlando back to Tennessee!

Got rerouted from a straight flight from Orlando to Atlanta to Knoxville to a flight from Orlando to Detroit to Knoxville! Seriously!! Flight delay out of Detroit! Long day for what should have been a pretty easy travel day!

Two delays on two separate planes with parts they could not easily find and replace.

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

This planes staff was top tier. Everything went great and had a great flight home.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Service was professional and quick. Premium economy seat was comfortable given the class

I'm a United 1K member and have ben for 10 years. The gate agent had no control over the boarding process and had us passengers queued for hours as delays were announced. On the plane, the overhead air nozzle was broken so col over was powering through on me and the passenger next to me. Not a great experience for a million miler on United. Feel free to contact me. Josh Smigel - DM426089

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.
