My baggage was in another flight, anit was delayed for one hour.

They canceled the flight 30 minutes prior to departure without any heads up.

Pleasant flight, now wifi, but did get pushed to the exit row gracefully cause I am a tall man. Was a pleasant thank you.

Long flights are best when the seats have movies and shows to watch.

The absolute coldest flight I’ve ever been on, even with a sweater and zip up sweatshirt. Was miserable the entire flight.

The cabin temperature was very warm. Flight attendant did not help when my 3 YO needed to go to the bathroom and it was close to landing time. She knocked and opened the door. I would appreciate more empathy towards the situation.

The flight was diverted and departed from San Jose instead of San Francisco. This could’ve been executed more smoothly because after arriving in San Jose it seemed like nothing was being processed correctly as needed for the gate agents to do their jobs well and the flight to leave on time

watching out the window as the loaders bounced the luggage onto the carts as it was deplaned made me understand why some of my bags have been destroyed on the airline.

I went Premium otherwise it would have been a long wait. On board I only asked for a cup of hot water and got lukewarm. Cabin crew have poor to no service. But great flight; it went smooth.

Great flight Pilot was friendly and kept us informed when small delay to de ice plane

There was a loud squeaky sound the whole time we were flying.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

I was sitting at comfort +. One of the Asian male crew was so loud when he delivered service. When he asked questions or what food you need, he was shouting. He must be a prison guard before going Delta.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Space and comfort was good. Staff could have been more helpful and friendly.

Crew was great. However the seat I had would not recline and stay put. It would spring back to upright. Hopefully they can check the seats and maintain them. Otherwise the plane is clean and the crew is very friendly.

Boarding in Seattle is always a mess. Sat in Deltas new domestic first class cabin. Everything was great except I found the seat cushion to be fairly uncomfortable. I’m a bigger guy so take that into mind (6’2” / 300 lbs.). Crew was meh.

Like most domestic flights in the US, you are basically on your own with this airline when it comes to food, so be sure to purchase meals and drinks ahead of time or expect to arrive starving and dehydrated (like I was).

The net issue I had was with the gate agent. We had added a carryon to our boarding pass when we checked bags. When I got to the boarding gate the agent was rude asking why I had a backpack - I said I added it - even had an orange tag on it. She ripped my tag off and swung her monitor around to show me how she was right- saying it isn’t wasn’t listed - only a checked bag. I explained again that I wasn’t sure what the issue was but I wouldn’t have an orange tag if I hadn’t added it. Then she finally checked my husband’s boarding pass and found that the agent at checkin had added my carryon to his boarding pass instead of mine. She sent me on my way without my orange tag. Was a bit embarrassing for me the tone she used with me assuming I was trying to get away with something.

Gate agent asked if I could switch seats so a family could sit together. Agent moved me to a seat in the front of the plane, no charge. It was easy. The agent did a great job.

Great seat space. However food and drink prices outrageous. Jabbing to pay for a carry on bag or stuck paying at the gate too much.

Every Allegiant Air flight I've ever taken has been delayed. This flight was delayed a full 2 hours. It was excuse after excuse after excuse. It was a flight from southern Florida. They made us board the plane on time, but made us wait for 2 hours on the tarmac. Because the engines were kept shut off, so was the air conditioning. One can only imagine how hot the air was in the cabin over those 2 hours on the tarmac, while in the hot Florida sun. Just terrible.

Actually, for the price, I'm willing to put up with a little discomfort (upright chairs) and at times inconveniences (like any airline), lack of entertainment (I can bring my own). My flight was non stop and smooth. I would fly this route again.

The flight was delayed 6 hours and we were only offered an $8 food credit. My husband stood in line to get the credit for 45 minutes and when he got close to the end of the line the computers went down.

Worst ever! Flight cancelled supposedly for weather even though we k ow of many others who flew into Bangor same time no problem. At the airport there was no customer service at all just refund and no possibility of rebook for 3-4 days. Aweful won’t fly with them again!!

It’s a budget airline so adjust expectations accordingly. Nothing is without a fee but such is necessary for tickets to remain so affordable.

No complaints. It’s a budget airline so can’t expect any frills.

My TSA number was missing from my ticket which shouldn’t have happened since it’s in my file. The on board flight attendant who was a male, did not want to help me put my luggage in the overhead bin and made a very rude comment and was very unpleasant. The good… the woman who fixed my ticket with the TSA number was excellent and I had extra legroom which was perfect.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

The WiFi didn’t work and the seats are too close together. Very uncomfortable.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

Too many fees (but that seems to apply to all airlines nowadays)

Over two hours wait to get wheelchair assistance from arrival to the departure gate for LA was unreasonable even though there appreared to be heavy demand.

The flight and crew were fine. The entertainment- the sound was so bad through the headphones I could barely understand it and it was a show I had seen before. The food might have been fine but having to have an account with united in order to access the app in order to pay for the food was rage inducing. I had entered my credit card info at home and logged in as guest but that wouldn’t allow the “wallet” tab to open in the app. And then the wifi was so bad that it took about 45 minutes to fully log in and get all the info working at which time I missed the food. You shouldn’t have to give your address, email and phone number in order to get a hamburger.

Unfortunately our flight was delayed by 45 minutes due to Kate arriving aircraft. Once we stated everything was great.

Crew was unhelpful in boarding. Did not help passengers board and store bags efficiently. Did not alleviate tensions as passengers had to stow bags then return forward to seats. Baggage rules are unreasonable. Will fly southwest next time

Flight was absolutely sold out, so that just makes the crews job that much tougher. I will say people (customers) are behaving better over the last year.

I like the united App ,easy to check in and baggage.

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

I can say I will not be taking this airline again any time soon. Seat were uncomfortable and too tight. Lack of chair screen and little overhead space.

Poor availability of food. Cold cabin temperature. Extremely long waiting time for a flight attendant to respond to a call button signal.

2.5h delay due to unruly passenger in first class. Had to be removed from the flight. No food unless pre ordered. Didn't know we would need it because of delay.

Only my carry that was taken and found it in my final destination

The flight landed at LAX we were then bussed to collect our bags. That process took nearly as long as the flight. Luckily we weren't in a hurry!

We had a humorous and kind flight attendant, boarding was efficient, flight smooth, pilot gave updates and was humorous too, two drink services was very helpful. In flight entertainment is always appreciated
