Cons: "Alaska airlines suck"

Pros: "So much food service on board"
Cons: "Boarding organizer in Japan should be better"

Cons: "Flight was delayed by about an hour."

Pros: "Comfortable flight. On time."
Cons: "Nothing"

Pros: "People were awesome."
Cons: "Coffee tasted burnt."

Pros: "Boarding"
Cons: "Three hours waiting for various issues to be fixed, only offered water once"

Pros: "On time, all as planned"
Cons: "30 minutes late but because of CO try ruin at SeaTac."

Pros: "Boarding process was very smooth, easiest it’s ever been. I was surprised the emergency exit rows weren’t filled."
Cons: "The inflight WiFi with T-Mobile didn’t work. I wish they had a wider snack variety"

Pros: "The crew did their best to make a bad situation better. Alaska Air a very decent company and usually have good flights with them. They offered me a free cocktail after a family with 3 little kids took my seat to sit together. A cocktail at 9:55am doesn’t really appeal to me however. It was a 2 ½ hour flight so I could grin and bear the discomforts. Everything else went great ...baggage arrived an was in the carousel quickly although the $25 baggage fee slap is annoying on an already over priced flight. I still love Alaska"
Cons: "I am 6’2" and a difficult time with comfort in standard airline seats. Today’s flight with the family taking my assigned seat put me in the last row against the rear wall. Super scrunched for me then to have a very large couple flying non-revenue squash in next to me made it just that much more uncomfortable. I wish if you have kids you would go the extra mile and pre-pick seats like he rest of us .... not a hater people just like courtesy is all."

Pros: "Timeliness"
Cons: "No tv’s"

Cons: "Flight was cancelled. I was rebooked on a different flight without any input from me. When I called to get booked on a flight that would work with my travel plans I was placed on hold for over an hour. I was finally rebooked on a different airline."

Pros: "Good room and not just a tiny little jet. Kind pilot and crew"
Cons: "Getting delayed for take off"

Pros: "All staff were very courteous. Boarding went very smoothly"

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: "all announcements sounded muffled and difficult to understand both on the plane and by women making the announcements just prior to boarding. I upgraded to first class on the flight back to SLC so the return trip was more enjoyable. Non stop is the only way to fly if at all possible. Please have your people speak into their microphones slowly, clearly, and loud enough for their instruction and/or information can be easily understood."
Cons: "you asked about the quality of the "food"; please, crackers for food? The flight was delayed for an hour and then we are served crackers! I have flown both Southwest and Alaska; Alaska is by far the better airline even though your flight attendants act bored out of their mind. In their defense however, dealing with 150+ people in a confined space has got to be just shy of having a frequent nightmare. I will definitely fly with Alaska again."

Pros: "nothing"
Cons: "worst"

Pros: "Really like the E175."

Pros: "Service was great"

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: "The pilots and flight attendants inspired confidence and enthusiasm for travel. We arrived early and I felt safe. Crew was courteous and professional. Gate agents were not bag nazis."
Cons: "Seats were uncomfortable, limited entertainment options, and food is very limited."

Pros: "Each of the flight attendants were very pleasant and were helpful with me and my baby."

Pros: "Pretty standard Alaska Airlines flight. Crew was friendly, boarding process was smooth."

Pros: "inexpensive flight"
Cons: "Although flight was full and too many carryon bags they wouldnt do skycheck (gate check) except for those with status. REALLY!?!?"

Pros: "Was able to upgrade to first class when checking in online. Wonderful"

Pros: "And same overall. It was fine."

Pros: "How smooth the ride was. It arrived early."

Pros: "The crew was great very friendly. They made everything as enjoyable as they could over all great flight"
Cons: "No complaints"

Pros: "Air circulation"
Cons: "Middle seat and space"

Pros: "It landed safely."

Cons: "They sent my bag to Santa Barbara."

Pros: "When I had to change a flight on Alaska, because of a delayed flight on another airline, the customer service rep from Alaska was unbelievably helpful. Even after I had to hang up mid-conversation to board another plane, she arranged new flights and refunded me the money I had spent on an upgrade for the earlier flight. First class treatment!"

Pros: "This was my shortest flight for the day, just over 2 hours and it was a bigger plane, had monitors in the seat backs, served drinks and snack."
Cons: "I think entertainment should be free. There should be a charge for wifi, because people can survive without their computer/phone for a few hours. But, if you have already put the monitors on the plane, how much extra money per year would airlines lose by offering a free movie...?"

Cons: "We were not told our passports needed to have an expiration past six months of travel even though we got back before the expiration. We entered our passport info including our expiration dates and we’re given no warning. We even had our boarding passes prior to showing up at the airport. We will not use Kayak in the future and will book direct through the airline moving forward."

Cons: "charged a surprise of $175 for my third bag although Kayak mentioned i should be charged $75 at the time of booking. AA says it is due to Jordanyan Airlines, why was I surprised by this extra charge?!"

Pros: "Left on time, relatively comfortable considering I had already spent almost 9 hours on a previous flight, landed 30 minutes early"
Cons: "Mixed feelings about the entertainment app, I was pleased that something was available at all, however had the person sitting next to me not mentioned I needed an app to watch the in flight entertainment moments before it would have been too late to use the internet to download it, I would not have been able to use it, unless paying for a limited time package from AA to use the internet to download the app. A better job of advertising of the gogo app is needed more than the booklet in the seat pocket. Also I was only able to watch one movie, after that the system kicked me out saying high usage was making it not work for me. The gate changed a couple of times which had me trawling up and down the H and K concourses, could have done without that after the 9 hour journey I had already taken."

Cons: "no charging station"

Pros: "They were so helpful as we checked in and checked our bags! :)"

Pros: "Lovely service, but less comfortable plane... nothing terrible though"

Cons: "Dry / borderline rude staff and hostess. Dated plane. Tiny seats. But that is pretty much the baseline of airlines in the US. When will carriers start to take note from International carriers..leaps and bounds ahead."

Pros: "Long walk and less than an hour. Very difficult for senior. No assistan e available."
Cons: "The pain from carrying bag between gates"

Pros: "Snacks and entertainment"

Pros: "Other than a 2 hour delay due to a mechanical issue (identified after everyone boarded) the flight was ok. No electical connections for equipment. That would be an improvement. Also, out of a lot of meals that people request, and that was at the beginning of service in the premium seats."

Pros: "Delayed"

Pros: "He enjoyed everything about the flight it was comfortable the crew was excellent he met nice ppl thank you for the safety and class."

Cons: "Longer flights should have screens in the headrests"

Cons: "Going through immigration in Dallas is a disaster. The wait is eternal. None-US passengers seemed to get processed faster."

Cons: "Despite arriving more than an hour ahead of time, I had to wait in a long line to get to the ticket counter and by the time I got there the assistant refused to check my bag. I then had the choice of catching another flight standby, possibly not even arriving on the same day, or changing my ticket for an obscene amount of money. I hope to never deal with AA again."

Cons: "Flight was late. More than doubled my layover time"

Cons: "The captain announced that the flight crew exceeded 9 work hour per day due to the takeoff delay so the passengers were forced to sit and wait in a stuffy stationary aircraft for 2 hours prior to takeoff until a different crew could arrive to service the flight."

Cons: "As it was the continuation of an international flight, I believe I travelers like me deserved to be treated with free food and not just drink and water."

Cons: "i did not rate food and entertainment because i did not partake."

Pros: "The pilot was charming, and really hugged Mt. Rainier on the way in - Made for an incredible view in the moonlight!"

Pros: "I was upgraded to the comfort economy after waiting 10 hours at DFW for my flight."
Cons: "After being in DFW airport for 10hrs all I wanted to do was watch a movie on board and sleep. Go figure, my TV didn't work. I called the attendant and she said she would reset them. The "resetting process" took a while. She attempted, and the other stewardess did as well. They said that the TV issue that *some* of the people were experiencing wasn't able to be fixed by them and only by the company that provides it's service. So there wasn't anything that could be done. I know that at least the two guys that were traveling next to me had issues with the tv monitors as well. It was just driving it home that I will never fly on American Airlines again. I don't ask for much these days while flying, it's not like it's a luxury anymore. But the saddest part is that customer satisfaction is completely out of the question. Just pay the extra money and fly another airline. -Deidre Fugate"

Cons: "Delays"

Pros: "I did not like have to stay in a hotel room when I could be sleeping in my room I'm on medication I don't even have my medicine with me because American Airlines had engine trouble in Dallas we went back to the Terminal 3 times before they ever got it fixed slit throat me late getting into Seattle and I missed the flight to Yakima I don't feel that this was my fault I didn't nothing to delay the airplanes and I walked as fast as I could to the terminal on in Seattle so I didn't have such a pleasure to little trip but your airline get put me up in a hotel but it's still not does not change the fact I have my blood pressure medicine and about 10 other medications but my blood pressure is the biggest and I will think twice before I fly Alaska Airlines again"

Tix were booked and paid by two different parents and times. Agent relented and waived fee. At the gate we were again challenged and had to go thru it all again. No more United for us!"
