It was not a good experience, the flight was delayed 3 hours, the gate staff were super pushy to get bags checked claiming it was a full flight, there were about a dozen open seats from what I could tell. The intercom from the pilot seemed to be broken, it sounded like the pilot was speaking with a mouth full of marbles.

It was not a good experience, the flight was delayed 3 hours, the gate staff were super pushy to get bags checked claiming it was a full flight, there were about a dozen open seats from what I could tell. The intercom from the pilot seemed to be broken, it sounded like the pilot was speaking with a mouth full of marbles.

The food was terrible, worse that what you get with UA, an already one of the lowest standards to beat. How cheap one could be, providing that kind of junk food in first class. Unbelievable! The seats were not very comfortable either. And there were no screens either, not that I cared much but for you to know.

The aircraft was extremely warm the entire flight. After we landed we were stuck on the plane for another 45 minutes without a gate to deboard from. The smell of exhaust from the engines in the cabin along with the heat inside the cabin made the flight uncomfortable.

Flight cancelled and deplaned. Rescheduled 8 hours later at a different airport. Ended up at destination but late.

The seats are very small. I’m 5’ 3”, so don’t think I should notice. The food selection was non existent and very disappointing. 5 hour flight plus TSA, etc. I would have appreciated a small salad, crudités. Something fresher not just chips.

We appreciated that the flight attendant came through 3 times with drinks or water on the long flight..I was also glad that they were separating out recycling! I would have liked a 12oz sofa can instead of 7oz, but that's a minor quibble. The knee space in economy was also better than most of Alaska's competitors.

I liked the free snacks and drink. I liked the onboard entertainment. I did not like the WiFi cutting out in middle of my movie.

Flight from LAX to STS das excellent. Flight from DCA to LAX was troubled by the previous flight returning to the one DCA gate putting our flight in jeopardy. However another gate was arranged and that flight was a bit late, but was handled exceptionally.

Boarding process was poorly handled by the gate crew and the onboard crew. No effort was made to provide equal treatment to passengers with overhead bin space. Crew seemed disengaged and unfriendly.

Plane seats are comfortable and seemed more roomy than others I have been on. Playing was clean and flight crew friendly. Passengers who have a connecting flight should however be allowed off the plane first

Vegetarian selection could be better. Bread was too hard to chew.

Crew was friendly and competent. Food, wine, and entertainment were excellent except the raw tuna on the flight to Split. Recommend against serving that - at least as the only option. Many medical conditions do not allow people to eat raw fish.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Overall a good experience, however Wifi was not working on the flight.

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Human interaction. Thought there would be more service-even a smile would have been nice.

Incoming flight was delayed, delaying boarding. It then took 30 mins to take off. Took 20 mins to get to a gate because they changed the gate last minute, crew weren’t ready so there was no one staffed to work the jet bridge. Boarding was so disorganized as is usual with American because everyone just stands around the gate regardless of boarding group.

Delays with no explanation. It could have been handled better.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.

Flight boarded, departed and landed on time. Excellent service from flight attendant in FIRST

This was one of the most frustrating travel experiences I've had to date. I had changed my flight day of to this one as it was slated to depart on time. It ended up being so delayed that my original flight took off before this one did. The boarding process began but eventually stopped and everyone had to get off the plane as a problem was identified. The person at the front desk just tried to laugh it off as if this wasn't already a huge inconvenience. From there, we eventually got to board only to sit at the gate for an additional hour because of some additional issue. This was extremely frustrating and caused a lot of stress.

It was a little concerning to hear the ground crew arguing with the flight crew over baggage space. Instead of taking them and checking them, they started checking for space in the first class cabin moving items around like the flight crew didn't know what they were doing. I was embarrassed for them.
