Customer service of one flight attendant, impersonal to asking questions

The ground crew was very good. They communicated clearly and continued updating. The flight crew was fine. The flight crew on the March 20th flight from MCI to Portland was excellent.

Everything ran like it should. Staff was professional. Looking forward to flying with them again.

Process of checking bag, boarding, etc. was all very quick, easy, and streamlined. Only problem I had was the seating: very cramped and uncomfortable, but I suppose that’s the perils of coach. Thankfully it wasn’t a super long flight so it didn’t ruin the experience overall.

Didn't buy food and did not use entertainment as these were not the purpose of my flight.

The customer service personnel were excellent. We had pre-ordered two meals but they could only provide one of them; they substituted the meal with a snack at no charge. Flight was on-time.

We had to take the train to our next gate but had time to eat a meal. When to our next gate and asked employee about gate and got informed that gate had been changed so back on train to next gate. So thankful she was there and informed us of gate change. Because of the issue the boarding was slow but employees were there and busy helping all and keeping it organized.

We had a little trouble with boarding as the gate was changed at last moment and we didn't realize it.

The flight crew were excellent but everything up to the flight was not. As we arrived extra early for our flight we had to wait 2 hrs to check our baggage, took 30 min to get through TSA, Alaska changed our departure gate four times, with one gate being at the end of concourse C then changed to concourse N which meant walk all the way back then down to the trams and a ride to N terminal then a walk to the end of this terminal. Once on the plane flight went well.

Through no fault of their own, we took off two hours late because someone on the plane arriving from Las Vegas had been sick and had declared he had the Norovirus. In addition, they were unable to locate a necessary new part for the co-captain's chair. As a result, they FINALLY got us a new plane to board, but, because if was a bigger plane, they had to redistribute us for gravity's sake. Next, they had to wait on paper work, which had to be completed by hand and then put into the computer. The best I can say--which I recognize is the most important thing--is that we arrived in Kansas City safely.

Great job! My family doesnt fly often but we felt safe 100%

Communication about the delayed flight was poor. We were told to move gates three times but that was bad information. We went from gate 128 to gate 126 and then to gate 123 and back to gate 126. Communication about the delay was bad. Ended up being 1 1/2 hour late getting home.

I have roller bag with food and medication told me I couldn't bring on my 2nd flight today. 15 years flying with SW never an issue with that bag.

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

Flight was delayed due to plane not passing inspection And one of the crew had to time out and we had to wait for another one A 3 hour delay

It was one and half hour late... Not sure if any other experience matters.

Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.

It was 2 hours 45 minutes late, for no apparently clear reason.

Excellent. The lady boarding the flight was awesome. Very efficient, and she got everyone on line.

Planes never have enough leg room for someone my height so my knees were cramped and therefore started aching. Also, the Wi-Fi was down so I couldn't watch anything on my phone like I anticipated.

We departed early and made up time in the air allowing us to arrive 30 minutes early. Capt was incredibly genuine and thanked every passenger for flying with Delta. Completely humble and professional!

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

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

There was no FREE wi-fi nor entertainment screens at all.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

As we lined up to board they gave our plane to a flight going to Newark. So then we got delayed until they could find another plane. Flight crew was ok. I’m assuming since it’s a shorter flight they only offered water and coffee.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

Airport terminal was outdated, flight was on a small jet with no wifi

Essy to get on. The hostess gave very little pop, the plane was late getting in, and we are still waiting for our bags. This sucks. :/

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

We boarded and buckled and then deplaned due to no pilot. Had to wait over 3 hours for a new pilot. Not weather related, just poor management.

United Airlines was fantastic, however, UnderPricer was a nightmare. I got to the airport 4 hours before my flight. We are moving to New Zealand so had quite a bit of baggage (16 checked items) and so wanted to have plenty of time to get everything taken care of properly. When I went to check in they (United) could only find a ticket for me. The 5 tickets for my children were never officially ticketed. I called Underpricer and they told me it was United's fault and United told me that Underpricer just needs to reissue the tickets, but they refused to. I asked the Underpricer agent to transfer me to his supervisor as I was not getting the help I needed. He told me the supervisor was busy but that he would call me back in 30 minutes. 30 minutes came and went with no phone call. After an hour I called Underpricer back but they would not let me talk to the person I had talked to before, just told me that he was talking with the supervisor and technical support. I called again an hour later, was told the same thing. I tried again later, with only about 30 minutes until my flight was scheduled to leave (meaning I had been at the airport for more than 3 hours with my 5 children trying to get ticketed and board the flight). Also, my husband had moved to New Zealand 3 months prior, I haven't seen him in 3 months, my children hadn't seen their dad in 3 months, we were all extremely eager to get on that flight and get to New Zealand. The situation with the tickets did not get resolved until after it was too late to check our luggage and board our flight. We were devastated. My 11 year old son was in tears at not being able to be on his way to see his dad. Thankfully we were rebooked for the next evening, but that night it felt devastating. We'd been at the airport for 4 hours waiting. My in-laws waited with me and then helped me reload all our baggage and took us home to stay with them for the night. On the newly booked flights we could not sit together - my children were spread throughout the plane. So, even though I had paid extra to select our seats after buying my seats from Underpricer only two of us were able to sit together (thankful that my 11 year old wasn't all by himself, but not happy that my 14 & 16 year old daughters were seated by strangers). I really feel that Underpricer should refund me what I paid for the seating ($120 USD). It was a very frustrating situation and I plan on never using Kayak or Underpricer ever again.
