My flight was delayed 2 hours which led me to lose my connection. As a consequence, I had to spend hours changing flights and hotel reservations to arrange my arrival to Vancouver.

My flight was delayed 2 hours which led me to lose my connection. As a consequence, I had to spend hours changing flights and hotel reservations to arrange my arrival to Vancouver.

No Free Wifi and the flight was a tad late.

The plane was clean. They got us to the destination. It was very difficult to hear the announcements at the gate. The person was speaking way too quickly, and the sound system did not carry to all parts of the seating area at the gate. The flight left more than an hour late, which left many of the passengers missing connections.

Awesome. Great flight. Super nice people and I like the extra space

The first leg of the trip was excellent. Lovely flight attendants and comfortable plane. The second leg left a lot to be desired. The flight attendant was rude when I asked for a Diet Coke, the boarding required quite a long walk and the plane was crammed and uncomfortable.

Why was I charged for a glass of wine on one flight and not on another? Why no movie or TVs? It was a long flight.

5 1/2 hour trip. Nice plane. easy boarding. Could have used a bit more beverage service but it was a red eye flight and they didn't want to wake everyone.

Planes were on time. Pilot kept everyone updated. Crew was friendly and helpful

I have mobility problems and requested wheelchair assistance in Seattle and Anchorage and none was provided at all. Very disappointed. Only one gate agent in Seattle asked if I needed assistance boarding my flight in Seattle.... and only after three gate changes.... requiring even more extremely painful walking without assistance.

When I booked with Kayak, I paid extra for a window seat for the long flight, so I could sleep more easily. But when I checked in, they changed my seat to a middle seat. This happened on both long flights to and from Chicago to Anchorage. For one flight, upon request they changed my seat back to a window seat. For the other, they would not and said the Alaska Airlines does not allow seat requests.....just disappointing.

Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

Overall it was good. I missed my connection but I was put on another flight.

Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

The first flight was better in terms of the aircraft.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint
