Check in online didn't accept my confirmation number so i could only check in with assistance at the airport and ended up with s creepy middle seat.

It was the most expensive Alaska Airlines ticket I’ve ever purchased. I had a middle seat with no legroom or space compared to any other middle seat I’ve hadThere was a silver box under the seat that took up 70% of my legroom on the most narrow 737 max the crew flat out would not help they would not help with bags they would not help with garbage there was no coffee,It was definitely not one of my better experiences on Alaska.

Once again, Hawaiian Airlines upon checking in for our return flight, told us that we hadn’t paid for our extra comfort seats. This had happened on our incoming flight as well. Hawaiian Airlines had changed our flight and put us in standard seats. I sent them confirmation emails and receipts showing that I had paid for extra comfort seats and they ignored me and refused to accept my proof of payment. I ended up having to pay for our extra comfort seats again. On our return flight, once again, we were told we hadn’t paid for our extra comfort seats, which we had. I argued until a supervisor was summoned and researched further in their system and found that we had paid for them. If I hadn’t insisted, we would’ve been forced to buy our seats again or be assigned a standard seat. This kind of Customer Service is totally unacceptable. I would never use Hawaiian Airlines again if I have a choice.

The stewards were too loud and chatty with each other

If the flight from Seattle to Eugene hadn’t been delayed for mechanical reasons we never would have made it. 45 minutes is not enough time to deplane and get clear across a big airport like SeaTac.

This was a smooth ride all the way with plenty of space in main cabin for my 6 foot frame over 5.5 hours. The stewards were pleasant and attentive. We bought the tapas box which proved to adequate for us on this flight. It was pretty hard to find restaurant food to go that is vegan for us in Kona Airport so buying this helped lots.

set room is an issue and I am not obese.

Look at my previous review I just wrote on this survey. It was awful!

My experience from Lihue Airport was the “Flight Experience from Hell!” First, I was pulled aside by the Lihue TSA and searched thoroughly! Not once, but twice I was molested by 5 different TSA agents using some sort of smear cloth testing to see if I had been exposed to something dangerous! I can’t tell you what because they never gave me an explanation by the end of a near delaying incident of boarding my plane. More importantly, I was generously provided an airport wheel chair and personal porter because of my health condition. TSA even took your wheelchair apart! What’s up with that? I’m near 75, caucasian, never been arrested for anything, don’t do drugs or alcohol, and patiently and politely abided to their instructions for a full damn 20 minutes! Awful and humiliating experience especially when two different agents literally groped my testicles and crack of my butt! Then they lost the cap to my inhaler. When I got to my destination, a whole bottle of prescribed pills were emptied because of them not tightening the cap back on! Total BS and unprofessional by the lot of them! The short flight to my connecting flight to the mainland on Maui fortunately was uneventful. However the Hawaiian aircraft to San Jose was one of the worst flights I’ve ever experienced without crashing. I believe it was a 330 Neo. May I ask, why did you put three more rows of seats in the damn plane since I last flew on a Hawaiian aircraft? I had absolutely NO legroom compared to the last time I flew with you. And I’ve done a few Hawaii/mainland trips, even a RT to New Zealand before. Then, the icing on the cake was a couple with a one year old baby that literally cried and screamed for all but 15 minutes of the 5 hour flight to San Jose! Further, I couldn’t move my seat back even a millimeter because a car seat was placed from their window seat to the back of my seat! My Hawaiian flight was a freaking nightmare and fortunately will be flying back to Lihue direct with Alaska!

I only give it a bad rating because I missed my flight

Ever since Southwest starting charging for bags, passengers don't want to pay to check their bags, so the gate agents have to beg people to check their roller bags now because there's "not enough space". This was a terrible business move by Southwest.

Full cans of soda would be nice. A choice between two snacks would be appreciated.

Tried watching free movie and it kept freezing so I couldn’t finish.

All was good. I just had a hard time getting connected to the WiFi/internet during the flight

Sacrament staff are always polite and helpful. Airport is easy to maneuver and boarding is straightforward.

Great flight. Outstanding Service. Southwest was able to put us on a direct flight to Denver when the connection could have been affected by a later arrival to Baltimore. The direct flight was less expensive that the flight with the connection in Baltimore.

Delays delays delays. Late taking off, late landing, wait for a gate, etc.

Boarded on time but once we were ready for take off, the crew determined that, although every seat was taken, somehow someone was on the wrong flight. Delay, delay delay, announcements and ended up with one person checking EVERY ID against their passenger Manifest only to figure out it was a "clerical error." We departed 54 minutes late causing me to run in the St. Louis Airport to make my connection and lose the priority boarding spot I had paid for. Unnecessary delay.

I was re-booked onto another flight because my original flight was delayed and I would have missed my connector. I ended up in the “C” group after paying extra to be in the “A “ group on the original flight. At least if you’re going to re-book people, re-book them into the same group.

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

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

Salina to travers city was great! But the sept 24 Tranverse city was not! Traverse city to chichago was cancelled, i went to Denver & got to Salina 6 hours later!

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

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.
