Airline reviews

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.

Our flight when we finally got rerouted to a different destination than we were going was fine. But 2 days was taken out of our vacation because our flit was cancelled. We understand mechanical problems and of course don’t want to be on a plane that has mechanical problems.Wish there had been another solution.

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.

I behave had better flights this one was old and poor

Short trip from Honolulu to Kauai. Not a major issue. Only concern was the drop off of the luggage for departure. Only one person handling all of the passengers. She was busting her butt.

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.

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.

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.

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.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

Sat next to a one year old. She crawled all over the place and made me laugh.
