It was so easy to board using my boarding pass on my iPhone, and I liked what I was given on the plane for food and drink, and everyone was very friendly.

It was so easy to board using my boarding pass on my iPhone, and I liked what I was given on the plane for food and drink, and everyone was very friendly.

The flight attendant in the back of the plane was barely understood as she rushed through instructions to the point of being intelligible. She had a bored demeanor in her delivery.

On time, comfortable seats with plenty of leg room, nice staff. Pretty good!

dont re-route to San Jose. Re-route to closer airport. Provide shuttle bus to go to SFO, not just LYFT vouchers.

Staff seemed genuinely nice, not just going through the motions.

I would have rated the entire experience much better were it not for two things: 1. There was inconsistency between what we were told once on the plane vs. the answer I received to the question about "spreading out" from our assigned seats because the flight was sparsely populated, and the entire row we were in was empty but for us. I asked about one of us moving over one seat to make more room for us; before getting on the plane, I was told we could, which seemed like a sensible answer. Once on the plane, it was announced that we needed to stay in our assigned seats despite all of the empty space in our row, which seemed unneccessarily restrictive. 2. To add to the discomfort, we sat on the tarmac once the plane landed in Burbank for over half an hour waiting for a gate to become available. During that time we had to remain seated and buckled in, which was becoming more difficult as time dragged on, especially for my wife. If all of this was due to regulations, that may mitigate the sense of "needless" restriction somewhat, but it points to a need to make regulations less restrictive where it is not appropriate for the current conditions. The crew was not "nasty" about the restrictions, so I do not resent their actions, but it certainly would have been a much more pleasant flight if we had a few more options when it comes to comfort.

Flight left two hours late with no real explanation and they inexplicably had the heat running on the flight as well

I like Alaska Air fine. Great crew. Late departure still arrived on time.

Plane delayed, emergency light on so we couldn’t board- further delayed, had to sit on run way for an hour for other plane priority

Every one of the people at Alaska Airlines were helpful and kind. My complaints are systemic in the industry - small seats, tiny packages of pretzels (why bother?), and a general shabbiness that I attribute to the lion’s share of their profits going to execs and investors instead of building a better business.

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

Had a broken tray in business class. Crew just shrugged it off.

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.

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.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Crew was not friendly when I went to request a seat change.

Really impressive staff at airport and on plane, especially given how busy it was

Was a great smooth flight from Detroit to San Diego.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

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.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

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

For a 22 minute flight all you expect is for it to be safe and comfortable

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

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.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊

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.
