I would have liked if the flight existed. To be fair the federal government canceled it. But, since it WAS canceled, I would have liked it if Alaska Airlines had moved a finger to assist me rather then abandoning me with my luggage, unable to check it, for 14 hours in Portland. So federal regulations forbid them from storing my bag? Then at least help me find storage or SOMETHING.

It was all good, no delays which was a worry. All great

The staff was so kind and friendly! Boarding was efficient and communication was timely. I would seek out flying with Alaska Airlines in the future.

It was a pleasant experience. Considering we paid over $3000 for first class there really wasn’t anything special about first class. All the seats looked the same and everyone got the same great customer service. The only thing that was different between first class and couch was the drinks and the meal. We wouldn’t waste that much $ on first class on that plane again.

This was more with the third party booking through Kayak but my KTN for Pre-TSA, even though I entered it, wasn't assigned to my ticket when I got to the airport. I had to go through regular security. Also the Alaska app had trouble loading my ticket in the first place and I had to ask for it to be printed. Alaska Airlines was great but wanted you to know about this hiccup in the ticketing interface.

We sat on the tarmac for 25 minutes after landing and it caused me to miss a connecting flight. It turned a 7 hour travel day into a 14 hour travel day. That really sucked.

Process of checking bag, boarding, etc. was all very quick, easy, and streamlined. Only problem I had was the seating: very cramped and uncomfortable, but I suppose that’s the perils of coach. Thankfully it wasn’t a super long flight so it didn’t ruin the experience overall.

The boarding was confusing because the PA system at PDX was so quiet you couldn’t hear anything being said . The seats were uncomfortable. The food was pretty bad and I normally don’t mind airplane food. The flight attendants were not friendly. I learned upon check in that Hawaiian airlines had reassigned our seats of the second leg of the trip. I had confirmed and paid for special seats but they put me and my companion on standard seats in different rows. Hawaiian also did the same on my return flight after the flight times had changed. I happened to go online to check my reservation and saw the flight had changed. I gad received no notice. I saw that my confirmed seats that I had paid extra were gone. After much back and forth with the airlines they refused to correct their error. I showed them confirmation documents of my seat reservation and receipt of payment but they refused to correct the seat change or reimburse me. I had to pay $200 again to reserve the original seats. Shameful and manipulative. They basically held me hostage. If I wanted to be in that flight I had to pay up.

When I bought my tickets I up great my seats for extra $104 each seats 8A and 8B in the way back from Portland to Palm Springs they gave me the seats 15. I thought it was for round trip same seats . So I was very disappointed ☹️

One disappointment. There was a gate change from B8 to B10, they had announced it maybe 20 minutes before the boarding time, possibly less. I didn’t hear the announcement as I was listening to music on my head phones at B8. At the boarding time, I got up and asked the gal at the B8 boarding desk, why the destination sign had not changed and if the flight was delayed as there was no plane behind her through the window, she said that perhaps the flight was delayed and the screen will probably update in -5 minutes ( she apparently didn’t know the boarding gate was changed ( 2 down from our location) I put my headphones on and went back to sit down . Just before the B10 door closed, I got a phone call asking me if I was still taking the flight, I said. “Yes” but I was at the gate stated on my ticket B8, then I was informed of the gate change, I got up and ran to the gate, and down the hallway to the jet ramp. I was the last to board!! Very frustrating . I was shocked that I got no emails or text messages from Alaska informing me of a last minute change!!

Older aircraft, no meal, only food was for purchase. Not impressed United.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Always wish for more healthy, gluten free options. We have to bring our own.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

Other than a way way too cold cabinets for the entire flight, all was great

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

Premium Plus is a really good idea for longer flights
