the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

Very nice flight love the small aircraft. We had a wonderful flight attendant. Nice to see someone that really enjoys her job. Don't have her name but had a southern accent.

Seats in waiting area and on plane hard as rock. Fast internet on the flight was great! Crew was kind.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

The flight was on time and the crew were great.

I liked the fact that we arrived on time. What I did not like, I paid for a seat. Unfortunately a very large women sat beside me (required a belt extension). Her body spilled to my side. Not her fault but I had to lean to the left because her body was literally on my side of the seat. This caused a back ache. I was unable to sit straight the entire flight. There should be some form allowance (wider seat) for morbidly obese passengers. These seats are not designed for extremely obese people. I feel compassionate towards these obese passengers but I got off the plane with a substantial lower back ache. I myself have a degenerative disk disease and this did not help me

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

This flight didn't happen for me because of overbooking.

Everything was simple and easy. The lady at the gate was super friendly, I wish I had her name to share. She's a little older, dark-haired. You can tell she likes her job and would be a great influence on any young people training with her.

Your survey should include a "Not Applicable" response for those elements that were not utilized, such as food (unless your want me to rate the cookie I received) and the entertainment (unless you want me to rate the emergency landing presentation). Boarding was late, the plane took-off almost an hour late, and the gate to board changed five times while I was waiting there. At 1:00 pm the plane had not yet approached the gate for passengers to load, yet the information board indicated that the take-off would be 12:30 pm and its status was "on time". Curious.

Not cancelled the flight I had to rebook with another airline

The flight was delayed for an hour and there was no inflight service.

One stewardess a bit to impatient with older Asian couple.

On-time departure would be nice. It was delayed three times, and we ended up leaving three hours later.

Seats are too close together. I'm 5'8" and could not sit comfortable the entire flight. I will not book Rouge again because of the leg room.
