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

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.

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!!

The crew was the best I’ve ever had HOWEVER when we arrived in Salt Lake City there were no Alaskan Airline employees to be found so we weren’t able to leave the plane until ANOTHER airline took pity on us. How could that possible happen?

The pilot performed the smoothest landing I’ve ever experienced. What a light touch. And I’m an avid traveler!

Crew could have been friendlier, maybe I'm spoiled by SW crews. In flight wifi was good. Would be nice to have more food offerings on a 4 plus hour flight

Had to get off plane from prior flight even though I had to reboard same plane to continue to my final destination.

Everything a cheap airline should be at normal airline rates.

Plane crashed into a bus or some other vehicle on the ground while pulling out of the gate. No injuries, but wing tip was damaged and returned to gate for “maintenance issues” and we departed 5 hours later because the plane went out of service and new plane was flown in from a nearby airport, Midway.

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.

The ticket agents in West Palm Beach on Friday afternoon Nov. 7th were incredible in getting us on an earlier plane to Atlanta during the government shutdown. Had the taken our original flight we would have missed our connection. She did this on her own, We didn't even have to ask, and she did it all with a smile and showing genuine concern that we would be taken care of. We are very grateful and thankful. We fly often, and now we will be sure to fly Delta.

Flight delayed then cancelled. Misplaced luggage. Still do not have. Rented car 1100 mile drive. I had to buy some overnight Hotels clothes toiletries gas food at my expense. Still not home. Not sure where luggage is. Over 4 hours on hold to Felta

I truly love flying with Delta. They have always treated me with the upmost respect

Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.

Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.

Non stop on long haul is the way to go. Great experience

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

The crew was quite good, they came by often with drinks or to collect trash. But what wasn't nice was the flight was over weigh and several people had to be rebooked. I was questioned whether I should have a seat when I was getting to it. The in-flight entertainment kept buffering and interrupting. And the route took the airplane through high winds which caused us a longer flight

Wasn’t on the flight due to Alaska cancellation…also after all the rerouting, I was going to be on a later flight that left SFO at 7:47pm, which meant an almost 6 hour layover. That same Hawaiian flight was delayed for another 2hours.

I always love flying Hawaii and I have nothing to add

Everything was great and smooth. Given the short flight there was no entertainment but the rating does not give this option. My first flight with Hawaiian was a success all around.

comfortable but the food is horrible. I have flown Hawaiian several times now and no matter what they say the food is its the same squashed bread with melted goop inside. Tastes fake and isnt what they represent, its quite nasty. What happend to real food? And there is NO entertainment!! so not sure why they are asking for a review on that.

I was very, very cold and a stranger loaned me her sweater next to me. I didn’t wanna buy a blanket just for a four hour trip when I did not need the pillow or the earphones. I don’t mind purchasing a blanket, but I only needed that not all of it accessories. Cold air pretty much blew the entire trip. Two people in front of me both bought the blanket packages. Maybe that’s the idea. The crew was exceptionally nice and passed through multiple times.. the restrooms were very clean and usually accessible.

3 hour wait on customer service after flight was cancelled. Was bumped to a flight where I wouldnt have gotten to my destination for another 2 days. Had to fully refund flight and book a new one the following morning. Paid twice the amount for the flight than I had originally booked. Very disappointed I was not offered any sort of discount or points for all of the frustration, in fact the airline profited twice as much off of me by cancelling my flight and and changing my entire trip.

Very accommodating on flight changes when something came up. Definitely felt a notch above other airlines.

They we able to seat my companion and I next to each other. Plane’s temperature was very cool. Willl be more prepared on return trip.

What an amazing flight. I haven’t experienced this level of service in a flight in years. This will be the only way to fly to Hawaii for me in the future.

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.

Premium Plus is a really good idea for longer flights

7 hours delayed due to operational issues on United’s end. Basically laziness.
