Food was just ok..had snack box :( Crew was very nice

Passengers were not informed timely of delays. The staff appeared like they didn't really care about the passengers.

Food and entertainment aren’t a thing on these regional flights. But it was a smooth flight. Could see gorgeous countryside through the large windows. The earplugs are a nice touch for the prop engines but the hum of the engines did not bother me. Grateful the option exists to easily get from A to B.

Both flights were delayed going to our destination and leaving, and communication about the delays was not great by the airlines, now the crews were phenomenal and great to be around!!

Delayed. It's not our first flight with them either, it's actually our 3rd and all 3 were delayed by hours each time. It was a myriad of delays. On one flight we boarded after being delayed for a little over an hr, only to be told we were going to sit in the plane for another hour before departing. Once landed, we waited another 40ish min to get to our gate. On another flight, flight was delayed just under 3 hrs but atleast we got to wait it out at the airport terminal. Its just a bad experience overall flying with Alaska Airlines.

We had to take the train to our next gate but had time to eat a meal. When to our next gate and asked employee about gate and got informed that gate had been changed so back on train to next gate. So thankful she was there and informed us of gate change. Because of the issue the boarding was slow but employees were there and busy helping all and keeping it organized.

Very pleasant and the flight felt like it went by quick

All flight entertainment is from your own device and there was an $8 charge to connect. also 1 drink and a small bag of pretzels was all that was given to us. other that that the seats were good and the flight itself was as expected.

It is very bad they do not give you money back

They lost our bag and it took them days to find it. Terrible communication and lots of lies about where it was. Their system hasn’t merged with Hawaiian yet they route people on shared flights with Hawaiian, creating an administrative nightmare.

I like for how they process during check in. It was very smoothly.

The flight was scheduled for 2:30 PM. Early in the morning we got a text message saying the flight was delayed and rescheduled for 3:00 PM. We got to the airport with that in mind. Then we got a message during check-in at the flight was rescheduled again for 2:30 PM. We almost missed our flight. In fact, our bags Were told that they would not make it. At the end, everything worked out. But it is very stressful.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent check-in. Crew was good. Excellent communication from flight deck.

Great overall. There was a bit of turbulence so they could only serve water because too much turbulence for the carts. Was glad they prioritized safety though

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

Flight was delayed long enough that I was misding my connecting flight. The agents could not get me on a comparable flight, nor could they get me s Main Cabin seat I had paid for, nor could they get me on a comparable connecting flight. The gate agent would not issue meal vouchers, even though I was delayed over six hours! I had to spend over an hour and 15 minutes with customer service on the phone to See if they could get me on a better flight and get a meal voucher. Customer service was not helpful enough in trying to find alternate flights and it Ended up taking me 24 hours for a 12 hour trip!! Delta does not provide upgrades NOR will they even give you a pass for a few hours to their lounge. They claim that they do not issue daily passes to their lounge anymore. I call BS since this would be no extra cost to them to provide excellent customer service and give you a few hours to relax in comfort when you’re sitting in a crowded airport and your flight has been screwed up for that many hours.

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

Same as ive said before. All airlines and TSA need a massive revamp.

Alaska airline sis usually great. However flying nowadays is so stressful and feels more like an interrogation rather than a fun part of the vacation experience. From the TSA to the cramped seating it feels like i am entering a concentration camp having my picture taken via TSA and being forced to have my body scanned. Then we are forced to sit in beyond cramped conditions where our knees are crushed into the back of the seat in front of us with almost no movement possible constantly being reminded to put our seats forward when we want to alleviate the horrendous pain of our knees being shoved into hard plastic. My knees looked like i had kneeled on gravel for 2 days straight after flying for a total of 14 hours for my roundtrip. I keep hearing from our elders about the jopys of flying in the 70s and 80s but now it feels like the joy has been removed as a means of acquiring more financial gain by the airlines. Not to mention that my flight via hawaiin airlines was delayed so long that i had to miss my connecting flight which then forced me to miss another day of work and the only recourse i had was a wonderful conversation with a lady via Alaskan Airlines when she got me a new flight the next day due to the delay. She was very pleasant and helpful. She got me onto a nother flight the following day but when i have to travel 2 hours from springfield Illinois to st louis it was a huge hassle having the delay in the first place. Not even the tiniest bit of compensation was offered either. Not a voucher, not a free meal, not a slightly better seat, just a reschedule when in no way was the delay or the missing of the connecting flight my fault. I want to reiterate that Alaska Airlines is really one of the best airlines overall. I fully understand they dont control the TSA, but it does effect the overall experience when TSA is making it feel like we are going through a re-education camp with rather strange videos playing on the walls the entire way through Security. With that said, Alaska should take cosnideration from years of past and make the flying experience fun again. I understand profit is important, but if just ONE airline made flying like it used to be 40 years ago and stopped making it such a money-driven experience, then i, along with many others would choose to fly more often. We see the smaller soda cans and we laugh, we see the tiny snacks and scoff, we see the ridiculous wifi costs and choose to not pay for it because we download our own prior to flying. Why not get everyone to use the wifi by making it like 2 bucks rather than 8 bucks? Make a much larger first class area with slightly lower costs so it doesn't feel like we are mere peons boarding a cattle car? Create some more leg room and watch how fast people are clamoring for your airline over others. Not one airline is actually catering to the general public, if they did, they would see so many people seeking out their airlines above all others and it is just that simple.

Both flights were late 2+ hours with ZERO communication from the airlines or their staff. No offers for compensation. WiFi didn’t work for streaming and they said to only use browsing but that didn’t work either. Waste of $$. No drinks only boxed water or apple juice. No snack. One of the worst flight experiences I’ve ever had.

The ticket and bag check in was chaotic at SEATAC. No clear communication or signage for bag drop off.

This was actually an Alaska flight. I was not able to check in online using the Kayak app or the web for Hawaiian or Alaska airlines. So I contacted Hawaiian and they advised that I had to go to the counter when I arrive at the airport. So I waited in line at the Hawaiian counter for 45 minutes. When I got to the ticket agent she advised that I needed to go to the Alaskan Airlines ticket counter. So I went to that counter which thankfully was not busy. I received my boarding pass and then went to security. I arrived at the gate as boarding was beginning. The frustration is that Hawaiian or Kayak should have directed me to the correct ticket counter. When it is “operated by” a average person doesn't know what that means. Kayak app was silent on what action to take when I was unable to check in online and Hawaiian just stated my ticket number and confirmation numbers were invalid. Communication is key and this process could be cleaned up. Thank goodness I am savvy and speak English, I can’t imagine this process for someone who may not be.

If I knew I would be on Alaska Airlines flying back, I never would have bought the ticket. My flight kept getting delayed and Alaska always seems to be late which is why I don’t fly on them.

Good. They changed our gate very late and then when we landed, we had to wait 20 minutes to get off the airplane because another plane was in a slot.

Very nice experience. The boarding however seemed somewhat mixed up, and we were delayed taking off.

Flight was canceled with no voucher of any kind and next available flight was two days later.

Boarding was chaotic. Microphone not working properly and second agent was distracted from task with baggage and late arrivals.
