Had to pay $8 for internet wasnt cool, no tv’s, had to use phone to watch movies, no food choices seemed available unless u ordered in advance maybe I'm wrong about that but seemed that way, no snacks were served. Seemed a very bare bones flight. But it was on time and safe so that was good

I liked that it didn't take 10 hours to drive here. Super short trip!

I had a horrible and traumatic bullying experience the last time I flew ( frontier). I was incredibly anxious about these flights. However, it was so relaxed, organized and the crew was efficient and polite. It was so refreshing and relaxing.

Terrible airport. It took over one hour to pass checkpoint and security gate. We stood under the sun in the long line

Paid extra $230 to check frozen fish on arrival to LAX. I was told my bags miss my flight and we’re gonna be on the next flight that comes in two hours later regrettably my family was here to pick me up so I had to drive all the way home to drop them off then turn around and come back if I had waited on Alaska to deliver them they told me that they would be delivered in 4 to 6 hours after 8 AM tomorrow which would’ve caused the fish to spoil stink and be a lost cause they would’ve put about $2500 worth of fish down the drain very unhappy with Alaska Airlines for not getting my baggage here, especially since I had to pay for the extra service

Jammed up security line. Security personnel excellent but facility is really cramped and lines long. Alaska Airlines was excellent.

We were flying 1st class for a special occasion. This was a Hawaiian airlines flight. It was exceptional. Very comfortable seats and space. Extremely attentive crew. Food was great for airline food. They provided tablets to watch and full headphones to listen. This was the best airline experience I have had in decades.

you could have gotten me there on the day I was supposed to be there, not a day later. Paid for 3 nights at a VRBO and got to spend only 2 nights there.

I requested wheelchair assistance in Seattle transferring gates and in Anchorage to get to baggage claim. No assistance was provided at all.

Reserved seats and yet did not get my original seat because someone else was seating in them and the crew member did not try to find out what was going on with the issue. My wife and I did get similar seats. This created concern and unnecessary issues.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

I believe that a four-hour trip should have a meal. Delta had none.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

I was uncomfortably cold on the plane. Other than that it was uneventful and therefore as enjoyable as a plane ride can be.

There was supposed to be a meal served, but there wasn’t and the major toilet was out of order

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.

The flight was comfortable with the exit row and great service

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

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.

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

Any flight to ORD after about 2pm this summer has been challenging. Flight was delayed getting in (coming from ORD) and that led to it not leaving before a ground stop due to lightening before they could fuel the plane, and so forth. They made up some time but we were still late in arriving at ORD, and that led to missed connections.

Food was ok, but not as good as I have had before on AA.

No issues. They did change our gate FOUR times in about 30 minutes which was mildly annoying but the flight was fine.

Great flight. No issues at all. I still think boarding could be more efficient but otherwise, a good experience.

Pretty good. The food was just mediocre, the boarding and crew were good.

The comfort of the seats was great, the crew eased my child’s anxieties and the fact that I had full cans of my beverage choice was great.

My flight got switched and my prepaid bag didnt transfer over properly so I paid to check ANOTHER BAG. I was placed in a middle seat and it was just miserable. At least it was a bulkhead row so I had legroom. The flight just never seem3d to end

4 hours late, including over +1 hour waiting in plane to take off. Baggage left behind too.

Sat on the ground in Cincinnati for 50 minutes before deplaning
