Pros: "Flight from New Orleans to Seattle was smooth and quiet."
Cons: "Since Alaska Air used an aircraft from Seattle to return to Seattle, mechanical issues created a seven-hour delay in departure. Alaska expected us to remain at the gate, even though they had no intention of replacing the aircraft that would take 5 hours to arrive ONCE it eventually left Seattle. Upon arrival in Seattle, we were told we could only continue to Anchorage by splitting up, each of us taking a different flight. I checked with gate agent because had received notification of ONE of my three bags being on the carousel at Seattle, rather than going to Anchorage. She assured me all three bags were going to Anchorage. Arriving there 19 hours after our appearance at New Orleans Airport, we found one of our bags had indeed been left in Seattle. 8 hours later, still no bag or call. Good thing there are a dozen Seattle to Anchorage flights per day."

Pros: "Alaska consistently provides an organized pleasant flying experience."
Cons: "One of the flight crew today was a bit on the grumpy side and made several negative comments about Alaska and about customers. Totally not typical for Alaska. Also - In Seattle had to load onto a bus and drive out to the plane.... another layer to a journey. They were well organized BUT"

Pros: "Alaska consistently provides a positive flying experience. They truly have a culture of positiveness and customer service."

Pros: "Quick boarding and deboarding, comfortable seats."

Pros: "I felt the trip was good."

Pros: "Crew was pleasant and very polite. I like that one carry on was included in my ticket. Enough leg room. Love the free in flight movies! Glad I didn’t have to purchase a beverage either."
Cons: "I will never understand the way boarding works. Did going from window groups, middle seat groups to aisle seat groups not work? I hate having to squeeze through and hope I don’t knock anyone in the face with my bag. I don’t like I can’t pick my seat and that my seatbelt is a little too tight. If I get a seat in the back I’m waiting for everyone else to get on and then for them to get off the plane. I guess I’ll have to pay the $75 fee for “first class” next time since that’s the only way to update my seat. And if I have a “saver rate” ticket - I should be able to still change my flight within 24 hours. I wanted to come back a day earlier and it was the same price! But I would’ve had to cancel and repurchase for an additional $200!!!"

Pros: "We left on-time, without delays."
Cons: "There was a loud child behind me, but that has nothing to do with the airline, unless they enforced a silent cabin more."

Cons: "Still haven't left and communication is poor"

Pros: "Simple ways that make the atmosphere in the air a little more welcoming and friendlier."
Cons: "Nothing."

Pros: "I was happy it was a nonstop flight on a somewhat new and very clean plane. Plenty of leg room, though the seat almost felt narrow and the person next to me was on me the entire trip. Seat comfort was good, I prefer firmer padding on a longer trip. Attendants were attentive and quick about helping passengers but felt like they didn’t want to be there. Boarding was also fast, though slightly confusing."
Cons: "I didn’t like that after I booked my ticket Alaska moved the time to much earlier in the day and I had to take off work. There’s no built in screen; tablets are available to rent, but for the price tickets are I shouldn’t have to rent something or use up my battery. Plus having to either hold my phone/tablet the whole flight or use what little space I have on my tray to prop it up isn’t enjoyable. Also the snacks were lacking, one bag of cheese crackers was my only option for a flight over 5 hours."

Cons: "40 mins late, really had to run to make the connection."

Pros: "The flight attendant was great! During the safety instructions, it was like he was dancing :)"
Cons: "I put my bad on the flight side cart and when I got off he flight it wasn’t there. It wound up with the checked bags. Thankfully one of the flight attendants was able to track it down for me."

Pros: "The crew was really nice and professional"
Cons: "We had to make an emergency medical landing which is fine it had to be done. But then we had to wait a while for catering to come and bring us food. Most of us had already gotten off the plane to use the restrooms and get food. Then because the caterers took to long they cancelled the food order and told us they were having fingers out food vouchers. It was annoying g cause we had already gone and gotten food and spent our own money. Now everyone booked it off the plan to get food and we now waited another hour for people to come back. So altogether the plane was delayed 4 hours they could have just given us the food on the plane for free."

Pros: "The flight crew was incredibly sweet and helpful; one of them even gave me their personal TUMS when I said I didn't feel well."
Cons: "The flight boarded 30 minutes early; I arrived to my gate at the time of when my ticket said boarding started, but they were already calling final boarding call for my flight. I completely panicked. The plane was clean but the seats are very close together and there were no complimentary snacks- even though it was a 6 hour flight. On my flight back from Seattle on Delta, we got a complimentary meal AND a complimentary snack. I was expecting my Alaskan flight to be better based on everything I'd heard from friends, but my return Delta flight showed Alaska up; it was a spacier plane with way more food offered."

Pros: "Flew in premium economy - relatively comfortable. They had really good cheeseburgers for sale. The flight attendants were all professional. Had a special captain who came out of the cockpit to speak to the passengers over the intercomm. He was funny, personable and helped get the flight off on the right foot. I have about 350,000 miles with Alaska and about twice that number on other airlines. This was the first time I ever experienced such a personable interaction from a pilot. Flight attendants can be entertaining but pilots usually are too serious to make the passengers happy to be on board."
Cons: "They did not have Priority boarding for first class and MVP."

Pros: "I always enjoy flying with Alaska. The crews are generally nice and the leather seats are comfortable, even in cattle class. I like that they often give out the Biscoff biscuits, yum. I had lots of room on several of my flights, on one of them I had an entire row to myself, which was awesome."
Cons: "The fact that even on 5+ hour-long flights they still charge for the food is a little silly to me. But maybe that's how they all do these days. Still, it's unfortunate, or, it might have been nice to have more than one snack served up on such a long flight. The wifi is a little hard to maneuver, even with an instruction card. The Go-go inflight thing is cool, but they don't really advertise that you need to download the app while you're still on the ground...which they should advertise in their concourses or something."

Cons: "didnt like the hour delay, but what can you do"

Cons: "Both of the two flights in two days were delayed to the point that I missed my next flight. Third times a charm"

Pros: "Good plane on time"
Cons: "I’ve got the latest iPad and software but entertainment system could not connect Only snack food for sale on an evening flight"

Cons: "My flight was changed by Alaskan air. Flight was good, just wish I could have left at the time I originally planned."

Pros: "On time leaving and early into SeaTac"
Cons: "Its a short flight. The prop aircraft are not very comfortable or quiet, but they are reliable"

Pros: "Love the crew service"
Cons: "My plane was delayed"

Pros: "on time"
Cons: "I have never been on a flight where I was bumped in the leg or arm repeatedly. Passengers were constantly up and down the aisle along with the carts hawking their wares. I trussed myself up like a turkey with the seatbelt so I wasn't on the armrest so as not to get hit again. My grandson who is a lot smaller than I, tried to put his head down to sleep on the tray table. He looked so uncomfortable. I know the deal is butts in the seats, but even the seat bottom is horribly uncomfortable. These planes have become cattle buses. I put up with it because there is no choice and I can't afford first class."

Pros: "Missed my flight at it was rescheduled for $25 without asking a questions"
Cons: "nothing"

Pros: "On time, courteous crew."
Cons: "First class was full. Paid to upgrade for what is referred to as Premier class I believe. Was in row 6 seat D. Crammed against the wall. Seats seemed abnormally tiny. Before even boarding the flight, the smell of the lavatory wafted strongly through the jet way. It only got worse from there. From the time we took off to the time we landed, the plane was absolutely saturated in an overwhelming pungent putrid smell, that one could only expect was from the lavatories. That aside, I personally don't understand what constitutes Premier class, or premium-class whichever the case may be. Anyhow, my experiences with Alaska have generally been positive, but this flight however was an absolute disappointment in a number of ways. To be clear, the crew was courteous and professional. I guess it's just been awhile since I have flown in the teeny tiny seats that I guess are considered standard."

Pros: "2 hours late"

Cons: "I had booked my flight to take off at 2:30 PM, but when I checked into London Gatwick, my boarding pass given was 7:30 PM. Of course there's no Alaska desk so I couldn't ask anyone there. When I got to Vancouver, they said they weren't sure why I was bumped, but there were seats left on the plane. However, I had to go to the gate to change my flight because I had a checked bag. Got to the gate, and of course, it was sold out. And they told me they weren't sure if the 7:30 PM flight would be taking off. So I grabbed my bags, made my way via train/bus/hitchhiking across the American border where my dad picked me up. Never got a single reason why I was bumped in the first place."

Pros: "Very good service"
Cons: "They sent one of two bags on an earlier flight than we were on and we thought they had got lost"

Pros: "All else normal"
Cons: "Delays out of bellingham due to ground crew not staffed to fuel our plane."

Pros: "Poor experience"
Cons: "Flight cancelled at the last minute."

Pros: "We had a flight attendant, by the name of Bob, on the flight from SLC to Sea-Tac. He was very animated and lively through the flight, for instance during the safety demonstration he would carry on conversations with those of us close to him seamlessly and effortlessly, plus make funny gestures -- such as a thumbs-up when the seat-belt was correctly fashioned -- during the presentation. His wife was the head attendant (?) who gave the instructions, and he had fun with that as well. These are two people who do their job well, enjoy what they do, and leave a positive experience in the hearts of those they serve. I think they would be a fantastic feature story in Alaska Airlines magazine in the future."
Cons: "I've never liked the limited food choices and entertainment on flights from SLC to Spokane or Seattle. I know they are short flights, but a little more could be put in. I know Delta has on-flight entertainment from LAX to SLC, perhaps this should be done."

Pros: "Friendly and competent."

Pros: "Friendly, welcoming staff. On time. Nice new terminal at Bellingham. Check-in staff found me a better seat for the Seattle to San Francisco leg of my journey without me asking for it. Great initiative!"
Cons: "Cramped seats. $25 baggage fee."

Cons: "The flight was 4 hours late. I wasted an entire day sitting in the airport. You knew that the flight was late hours in advance and should have texted or emailed me to say as much. Instead, i checked in on time, and within 10 minutes we went from 'On Time' to four hours late due to equipment and crew. Very inconsiderate and unappreciated to your customer. The flight should have been free after such an inconsiderate gesture on your part. Instead, you send me a gift certificate that obligates me to spend more money with you in order to redeem it, and then within a certain period of time. If I have choice in the future, I'll lean toward a different airline than yours. You clearly do not value my time nor my business."

Pros: "Nothing. I didn't take flight due to punishing re book procedure that Alaska employs to basically steal money from it's customers."
Cons: "They weight the value of 1st leg much higher than the return AND they want to charge you $125 change fee. My grandma passed away and I needed to reschedule my itinerary. Alaska stuck to their policies (you know, those pages of microscopic text that is written by lawyers for sole reason of screwing the customer.) I just felt really abused; told them to keep the useless "credit". I booked with Delta. At what point does a company forget who they are supposed to be serving? Perhaps the people that are actually giving you money and keeping you in business?"

Pros: "The crew was courteous and professional."

Pros: "Crew on flight was good. We left late but made up the time in flight."
Cons: "We purchased 2 one way tickets and were given confirmation of purchase. When we arrived at airport to check in we were told we were on standby only. If we could not get on the flight then the soonest we could fly out was 48+ hrs away, arriving in Seattle at 2 AM on Monday morning. we had no one available to pick us up, we live 1 hr away from airport. After many announcements and many incentives offered 2 young ladies did give up their seats and we could get on. The flight went well but we were extremely upset with the promise of confirmation and the obvious overbooking. It probably is what many airlines do but not good customer service was given to us. We often fly Alaska but this was a bad experience."

Cons: "All legs of my trip from San Jose to Seattle to Philadelphia and back were all delayed; so much so that on the trip to Philadelphia, I had to be rebooked on Delta; and on the trip back to Seattle, I almost missed my flight due to a 50 minute delay on the runway waiting. I found out that "officially", the plane was "on time" because the plane closed the doors on time. Also, same thing from Seattle to San Jose, we were delayed 30 minutes due to a tire that needed replacement. Again, "officially" we were on time, because the doors had closed and we were just sitting inside the plane."

Pros: "I've always liked Alaska, but they really blew this one!"
Cons: "Mechanical delay started as a "few minutes back to the gate", then 1 1/2 hrs sitting on plane at the gate without updates, then "get off the plane while we turn off the air", another 2 hrs without definitive info, then "we're bringing in another plan in a couple of hours", then after 5 hours of waiting, an announcement that flight is cancelled. Finally they announced a replacement flight setup for 8am, but at 4am, Alaska sent texts that the replacement flight was delayed till 1:30 pm. We finally left Palm Springs for Seattle at 2:40, 26 hours late. But the worst part of the experience was the terrible communication. A few e-mails or texts or PA announcements as the time passed would have saved about 90 passengers the frustration of waiting hours at the gate area and ticketing desk for info about options. Alaska should have been more respectful of its customers. Minimal effort was made to answer our questions."

Pros: "First off Bonnie at the boarding gate was phenomenal , She has an amazing disposition ( especially at 5:00 in the morning ) she greeted each and every customer by name and with a smile ! Our flight was delayed for 2 hours as we sat at the gate while problems were fixed . The Captain made sure he kept us informed as each problem occurred and was fixed . The rest of the flight crew remained patient and attentive , which of course kept all the customers onboard calm and patient as well . My daughter just moved to Seattle and if this is the norm for this airline I will continue to use them for my future visits ! Elizabeth"

Pros: "the service and on time"

Pros: "The turbulence was TERRIBLE due to the weather and the pilots did an amazing job at handling it and getting us there safely. The crew also gave my friend a voucher for towards a future flight when she offered an extra pair of her son's pants to a family whose son threw up after the bumpy flight. Thanks so much!"

Pros: "The in flight crew is friendly and courteous."
Cons: "My 06:05 am flight was cx'd on 12/6 due to weather condition. I was moved to another flight which would turn a 2 hour direct to 8+ hours to Las. It would not work for me, and there is no other resolutions that Alaska airline could offer. So I had to buy a new ticket from Delta at the airport and flew out at 7:30am. Noted the very next Alaska flight @7:30am and the rest of the direct flights for the day to Las were all on time departure flights. I must say that i am disappointed for Alaska's emergency contangecy plan and its response to a mild conditioned winter weather, and afterall the "best resolutions" that the airline could offer."

Cons: "There was a 20 minute flight delay before we boarded. They announced there were mechanical difficulties, which took further time. After we left the gate, we were told that our pilots had timed out and we would need to return to the gate to get a new crew. We taxied for a long time back to the gate, then there were further delays while they added the gas they had used in taxiing. In the end, we arrived more than 2 hours late. It is hard to understand why they didn't anticipate this and replace our pilots before we left the gate. This was the return part of a round trip ticket; there was also a more than 2 hour delay on our earlier flight due to mechanical difficulties."

Cons: "They kept canceling flights even though other flights were going out of Seattle and landing in Bozeman. But the gate agents were promising that the next flight wasn't gong to be cancelled and that I was going to have a seat, so I didn't book another flight from Seattle to Bozeman on a different carrier. So I spend 3 full days waiting at the boarding gate with the gate agent saying boarding would begin in 30 minutes the whole time. Finally they just sent me back home to Oakland. I missed my last chance to see my grandfather alive. He just passed away. To add insult to injury, they they wouldn't refund the ticket because I "used" the ticket for a lovely vacation to the Seattle airport for 3 days."

Cons: "The check in process was cumbersome with being able to partially get checked in at a computer kiosk and then having to wait in line to see an agent while other people are jumping the queue and not having to wait... then having stood in line for 10 minutes an agent tells you that you could have been in the "fast" lane... but there is no or little signage indicating which line you should be in.... that's frustrating. Don't expect your customers to be unconsciously aware of all of your convoluted business practices... put some signs out... we at least like a hint. Other than that, for air travel it was a very good experience."

Cons: "My initial flight was at 0800; I got to the gate before 0800 and was told I couldn't board the flight even though it was still at the gate and was still before the flight time. I had to pay to rebook my flight, spent over $200 in rides to and from airport, had additional parking fees and was several hours late to work. I have many family members who work in flight service so I understand that employees don't like to re-do paperwork; however, being there before the flight time and being denied cost a lot of work time and money. I have always had great experiences with Alaska so this one was quite a disappointment compared to their usual great service. :("

Cons: "Something unexpected came up and I was unable to fly out on the date the ticket was purchased for. I contacted the airline several weeks to see what options I had to switch flights, or get a voucher for a later date. No flexibility. I purchased a one way ticket for $125.60 and they have a cancel/transfer fee of $125. So I had a wasted ticket that just flew empty. I asked if I could transfer the ticket to someone else... They said $125. They told me if I had purchased the travelers insurance it still would be the same fees as well. Not earning my business."

Pros: "The crew was just fabulous. They give you excellent service with out attitude."
Cons: "What I didn't like was how they boarded the plain. I understand the logic of boarding back to front but not enough organization at that gate. Too many people bunched up because the rows were not called appropriately. May I suggest that after the first class, children and assisted folks get in the plain that they call passengers by sections, for example: the last 10 rows first, then the next 10 and so on. so everyone is not just blocking the front part of the gate. So it will be more orderly and quickly to board. Not enough was said over the loud speaker about how people should be boarding, as most other airlines board front to back first and that's my 2 cents. thank you."
