I booked my flight business class trip to Thailand with kayak, but my final leg from Seattle to Denver was not processed correctly though Kayak (according to Qatar Airways). As such my first class ticket for a three hour flight turned into a 9 hour flight from Seattle Anchorage to Denver economy middle seat and no one is willing to answer what happened or take responsibility!!

I booked my flight business class trip to Thailand with kayak, but my final leg from Seattle to Denver was not processed correctly though Kayak (according to Qatar Airways). As such my first class ticket for a three hour flight turned into a 9 hour flight from Seattle Anchorage to Denver economy middle seat and no one is willing to answer what happened or take responsibility!!

Pros: "Alaska Airlines is the best."
Pros: "The male steward was very nice"
Cons: "Flight was delayed on tarmac for 2 hours better communication"
Cons: "Delayed boarding but received notification from Kayak was good."
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: "Friendly crew. Great movie selection through gogo inflight entertainment!"
Pros: "Aircraft was clean and comfortable. Crew was efficient and friendly. The whole experience was excellent!"
Cons: "There was lots of entertainment available but plain old music was not an option. What if I don't want to watch a movie or TV, just listen to music!"
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."
Cons: "Seat cushions are too thin."
Pros: "Great on time too"
Cons: "Very happy"
Cons: "Still haven't left and communication is poor"
Pros: "The seat was comfortable and the plane wasn’t over booked."
Cons: "I didn’t like that we took off an hour late."
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."
Cons: "Two rows up from us, I kid threw up all over the center aisle as we were pulling away from the gate. We returned to the gate to allow a cleaning crew to board and clean. However, the cleaning job was rushed and left remnants of the throw up behind which smelled the whole 2.5 hour flight. It really felt unsanitary and unsafe being that it’s unknown what caused the child to get sick. It very well could have been a stomach virus and could have infected the people in rows around the incident due to the mediocre cleaning job. I understand that it’s important to keep flights on-time, especially for connecting flights, but the safety of the passengers and their health should ALWAYS be the #1 priority."
Pros: "Comfortable seats with nice details; power ports; drinks and snacks."
Cons: "Boarding in Seattle was ridiculous. Security took a massive amount of time, and we barely arrived in time for th flight despite arriving hours early. The attendants at the gate were a bit rude and begrudgingly accommodating."
Pros: "I really appreciated the Alaska Airline’s efforts to make up time after a delay on the schedule and ensuring passengers made their connecting flights. I was very impressed by the assistance provided, as well as the professionalism of the flight attendant who helped a passenger who fainted in the aisle. Well done"
Cons: "Delay in schedule"
Cons: "I missed the flight"
Cons: "i wish Alaska would fly straight to Denver from Montana. I fly from Montana to Denver a lot and it ends up being a whole day of travel instead of a couple hour flight."
Pros: "It was a short flight. The overhead bins weren't overloaded."
Cons: "Boarding was a hassle. The flight was too crowded. The food was non-existent.. Seats were uncomfortable."
Pros: "Personal touch"
Pros: "Drinks were complimentary once the flight finally got underway. The staff were lovely despite being exhausted and frustrated."
Cons: "The flight was turned back due to an officer’s medical concern. The individual was standing in the gangway laughing and looking healthy while the passengers had to debark the plane and wait for 2 more hours before resuming the flight to Hawaii. When we arrived the majority of shops were closed; it was 7 hours late. Alaska offered a $200 voucher to make up for this."
Pros: "I didn't have to set next to a 500 pound cow."
Cons: "Your beer and wine is sooooooo expensive."
Cons: "Food and wine way over priced."
Cons: "Both of the two flights in two days were delayed to the point that I missed my next flight. Third times a charm"
Cons: "45 minute delay due to fog"
Pros: "I'm a big fan of Alaska Airlines and their partner Horizon Airlines. I travelled from Edmonton to Denver via Seattle last night. All the staff if pleasant and treats you as a valued customer."
Pros: "Friendly staf. comfortable seats. And no charging for checknig my bags."
Pros: "This flight did not exist - I ended up with a flight from Bellingham to Seattle, but they cancelled that and I ended up having to catch a bus at 4 am to Seattle to catch my flight to Indianapolis. Now I have to track down how to get reimbursed for the bus ticket, which is not easy for me."
Pros: "Boarding was a breeze, crew communicated well, seats were comfortable, plane wasn't too hot or too cold"
Cons: "Had a problem with checking my baggage in anchorage which led to $300 being held from my account for 5 days. They refunded my baggage fee though"
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"
Pros: "Everything but…"
Cons: "You lost my backpack with $2000 worth of hiking gear that I will not be able to replace before I am supposed to leave on a trip. How could this happen?! This bag was full of all the material possessions in the world that matter to me."
Pros: "Poor experience"
Cons: "Flight cancelled at the last minute."
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: "Nada"
Cons: "not able to know my seat till a day before flight ."
Pros: "Almost everything. First time flying with Alaska Airlines thought the food would be better o thought the food would be better on such a long flight but it was enough to snack on until I got to Seattle great experience in between flights was able to get an earlier flight to Denver"
Cons: "Wish there was a little bit more offered for food but overall a fantastic experience mahalo"
Pros: "Just fine. Staff was helpful and actually very kind crew (stewardess) I don't recall her name but middle aged blond. Very nice."
Cons: "Charis could have more room and there was bad turbulence but what can be done about that? we arrived safe and sound and that was good."
Pros: "Early flight, and short. I think I slept through it. Woke up sore, but eh I'm not surprised by that. I'm a giant and no one woke me up for anything so I was satisfied."
Pros: "Glad I discovered Alaska Airlines!"
Pros: "It got cancelled due to 3 inch of snow. And I missed work in Denver because of it. Very inconvenient"
Cons: "I would like to not have it cancel"
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: "Offering price"
Cons: "Real price. Ridiculous after carry-on and other fees"
Pros: "Promptness of flight"
Cons: "Cramped seating"
Pros: "good"
Pros: "Their staff was awesome as usual no issues with the flight ."
Cons: "So many bags that were suppose to go under the seat infront of you that weren't. So that those of us that boarded last had to wait while stewarts removed small carry ons. So that our one carry on that fit in the box but not under the seat could be stowed. It would be nice if the smalls bags that are to be stowed under the seat were. The family next to me had 9 bags in the over head. There were two adults and two children 3 and 4."
Pros: "Roomy seats and plenty of legroom"
Cons: "The whole experience of making a connection in SEA detracts from the travel experience. There is little room for passengers to sit while waiting for their Alaska flight. It causes masses of people in the walkways, and makes it hard to walk through, or get out of the way for others. It may not be the airline's fault, but as I said, it detracted. I don't remember SEA being that overcrowded on previous trips. Our incoming flight was delayed due to weather. Again, not the airline's fault, but we were told we'd be able to make up the time and be on time in DEN. We were still late."

The plane was SO hot and we waiting 30 min for one passenger to get on. Sweating. Then the plane never cooled off because it got SO hot waiting.

Pros: "Everything basically"
Cons: "Nothing"
Pros: "1st class flight attendant sat through the entire flight (except for offering drinks and food early in flight). There were passengers NOT wearing masks through the flight but she wouldn't know that since she never left her seat"
Cons: "just about everyting"
Cons: "There are too many announcements on the screen before you can start watching entertainment. It takes about 15 minutes."
Pros: "Good crew."
Cons: "Plane was too warm. Once again I was next to a larger person in a middle seat. This is as much airlines fault as it is the person. As Americans get bigger seats keep getting smaller. Internet stopped working on the flight."
Cons: "Short flight, would have appreciated if when asking for pretzels the flaggt attendant didn't hand me the spare bag of his pockets."
Pros: "Really enjoy flying first class."
Cons: "Excellent"
Cons: "The plane we needed for our flight arrived really late so our flight was then of course delayed."
Pros: "Good entertainment choices."
Cons: "Uncomfortable seat with insufficient legroom wouldn't recline. Inadequate overhead storage (full flight)"
Cons: "The seat went back three inches. I was about to spasm after 4 hours. No movement whatsoever. The flight crew could have moved me but I suppose they were told not to as I had a cheap ticket."
Cons: "Sat waiting for gate for 30 min"
Pros: "Even on a full flight, there was enough overhead storage"
Cons: "Pretzels were lame"
Cons: "Flight got delayed. We paid for assigned seating for our almost 85 yo mom. And the change in flight no one asked for to get seated in the front of plane. Instead she was seated all the way in the back. It was physically exhausting for her."
Pros: "The crew was polite and professional"
Cons: "At Miami check in, American had 40-60 automated terminals available for self check, but only had EIGHT open for use. Caused a needless bottleneck and the transition from there to the bag drop was also poorly laid out and did not provide a logical nor efficient route from one to the other. fix it!"
Pros: "On time flight. We were even a little early."
Cons: "Those seats are just crammed in there aren’t they?"
Pros: "Crew was great"
Cons: "Absolutely no accommodation for seat assignments and the lady at the gate was so rude for even just asking to sit next to my fiancé even though there were tons of single people on the flight."
Pros: "No major screw-ups this time!"
Cons: "It's AA, let's not try too hard here."
Pros: "Crew was good, flight was on time"
Cons: "Old plane, no TVs"
Pros: "Crew was nice"
Cons: "Not enough leg room. They did a gate change and I almost missed the flight because nothing was announced and when I looked at my phone app it had the previous gate."
Pros: "Overhead bins were newly done with plenty of space since carryon can be placed vertical on side. Decide holder built into the seat was very nice."
Cons: "Flight was delayed so had to drive to connecting city just to make it home."
Cons: "My bags were not checked all the way to my destination, I had to get them re-tagged and checked for this part of the trip and the American Agent was EXTREMELY rude and made us pay oversized bagge fees even though our baggage was within the Qantas allowance, the main carrier for our flight."
Pros: "Pretty standard flight"
Cons: "Inconvenient timing and overcrowded with obnoxious children sitting on laps. No attempts made to change their behavior by crew or parents."
Pros: "The plane looks like new. Great seats, phone and tablet holders at the seat back, USB outlet and a smooth flight."
Cons: "The WiFi did not work and so no entertainment for a flight of almost 4 hours."
Cons: "The sound on the entertainment system in my seat didn't work well. Also, the flight was really late getting in to Denver."
Pros: "Landing and deplaning"
Cons: "Literally everything else"
Cons: "Didn't like the two hour delay, especially when I was notified only a half hour before boarding! This seems to be a normal thing for American Airlines."
Pros: "Great service in first class"
Cons: "N/A"
Pros: "David took really could care of our cabin. Likes his cheerful attitude. He was excellent. Hope you let him know."
Cons: "Flight departure was delayed for 30 mins by a flight attendant not showing up on time."
Cons: "Flight crew was late and didn’t try and make things move faster to make up time. Kept saying they wanted to go Puerto Rico and that’s where they should have been going."
Cons: "Flight was delayed by 90 minutes because the incflight mint flight was late"
Pros: "Easy and quick boarding. Excellwnt service in first class. Comfortable ride."
Cons: "Nothing. Excellent travel experience."
Cons: "3rd flight in two weeks suck sitting next to a morbidly obese person. They should be forced to purchase two seats."
Cons: "the drink service came through pretty late in the flight. i asked for hot tea. a few minutes later i was provided with extremely hot tea. about 10 minutes later it was a temperature i could tolerate drinking. about 1/3 through the drink i was required to throw away my drink because we were preparing for landing. i understand that, fine. bad timing. it’s just a drink. what was unsatisfactory is that the attendant rudely commented “you have to give us your drink. it’s not that long of a flight.” the comment made me feel like i had done something wrong even though i had just been drinking my tea as soon as it was at a drinkable temperature. i was not impressed with the attendant. also, there weren’t any biscotti cookies."
Pros: "The first leg had awesome pasta.Then, on the 2nd leg, Philly to Denver, they had a "pay for meal" option for turkey with Chutney sandwich - again, delicious. I should add that the service was very good as well."
Pros: "Staff was great!"
Cons: "Seats were really uncomfortable up and reclined. Overhead baggage was full by the time I boarded and there was no enforcement of the carry-on baggage sizes... This needs to be addressed and contributed to our lack of comfort, noting this was the last leg of an 18 hour journey. My body still hurts today after a good nights sleep."
Cons: "the new seats are awful"
Pros: "It’s been a while since I’ve flown American, but the aircraft was updated with a solid multimedia system, great moving map, and a standard power plug and USB port at every seat. That’s more than I expected, and was quite happy. Service was solid—no complaints."
Cons: "Good & bad — flight arrived late, but the honestly, the pilots did their level best to make up the time and managed to arrive w/in 4 minutes of the scheduled arrival. Well done."
Pros: "Confusion, delays, rude employees...you name it, this trip had it. I will do my best to avoid flying with these guys in the future."
Cons: "Flight delayed 15 hours. Poor communication and outright lies from staff. Unwillingness to help find or pay for a place to spend the night. Rude staff"
Cons: "Watched a very weird interaction between Muslim (with a hajib) women with a kiddo and desk crew. She wanted to sit next to her child on the flight and needed to switch seats to be able to. Woman was very gracious and understanding that she was asking for an accommodation. Ends up her flight to Philly had been moved to a different gate after they had found a volunteer to switch seats. Volunteer was totally unfazed but Desk crew made it seem as tho the Muslim mom was at fault for the time and trouble they had had to go through to accommodate her. She apologized profusely and was very appreciative for the trouble evernote had gone to for her. . As she walked away the crew looked at each other and shook their heads. Pretty crummy way to treat customers!"
Pros: "Missed the flight. Money was not refunded."
Cons: "Nothing"
Cons: "I can't rate it because they canceled my entire itinerary without so much as an email. I did not take my flight to Wilmington via my original flight. I had to book another flight because the change fees were too expensive. I did not know that my return flight to Denver had been canceled until I was checking in a few hours before my flight. I was told my ticket had no value. Awesome! It really stings that I then had to book a new return flight, and because I am a teacher who makes about $23,000 a year, I had to book the cheapest flight, which was with American. I do not plan on giving them any of my hard-earned money in the future if I can help it."
Pros: "No excuse on a night flight does the temperature to be 80 plus degrees on the plane."
Cons: "The plastic seats and extreme temperature was brutal. They shut the AC off of down somehow."
Pros: "Flight was on time through United since we had to be rescheduled from our original flight with American."
Pros: "Nothing. AA is the worst airline. Period."
Cons: "Rude flight attendants, delayed flight (as always), just AWFUL."
Cons: "Flight was delayed and then extended by 2 hours due to weather."
Pros: "Entertainment."
Cons: "We sat on the runway for 3.5 hours while the crew cleaned up a fuel spill and we waited for a different co-pilot."
Cons: "Unexplained delay in leaving but only arrived about 10 min later than scheduled. Took an hour from pulling into the gate for bags to arrive though which caused me to miss my shuttle. Never had to wait more than 15 min for any other airline at DIA."
Cons: "They did not check the toilets before we left so we were diverted to St. Louis and I arrived in charlotte 3 hours late"
