We received a check-in reminder the day before the flight, and it listed the flight at a later time. Correct flight number, same seats, etc. for 3 hours later. I called the airline to confirm and they had no record of the email. The info was wrong, and we would have missed our flight if we'd assumed it was correct. I want to know where/how we received this incorrect info.

Middle seat, elbow wars. I cannot understand why they load the front of the plane first. You would think it would be more efficient to load the back to the front. I believe it is. And it needs to be changed.
Paid extra $230 to check frozen fish on arrival to LAX. I was told my bags miss my flight and we’re gonna be on the next flight that comes in two hours later regrettably my family was here to pick me up so I had to drive all the way home to drop them off then turn around and come back if I had waited on Alaska to deliver them they told me that they would be delivered in 4 to 6 hours after 8 AM tomorrow which would’ve caused the fish to spoil stink and be a lost cause they would’ve put about $2500 worth of fish down the drain very unhappy with Alaska Airlines for not getting my baggage here, especially since I had to pay for the extra service
I was very pleased with this trip from Anchorage to Seattle and Seattle to Billings. Wheelchair assistance was rendered and gratefully accepted. Unlike my outbound flights to Seattle I did not have long, painful walks on a bad knee to get to airport gates. My thanks to the Alaska staff.
No issues at all other than the seats. Of all the airlines I've flown on in my life (this was my first with Alaska Airlines), these were significantly the most uncomfortable seats I've had - more so than Spirit Airlines. I'm a relatively young guy and mostly fit but oof, i was aching in muscles I didn't even know I had. Not sure if the seats are standard for the plane (if it even works like that) or if the choice to use cardboard as cushion and 90 degree angle back rests was a decision, but it wouldn't honestly make me think twice about flying with them again. Other than that - perfect flight. It was quick, crew was nice, ride was smooth so all things considered I appreciate the last minute availability offered after a sudden relocation on my part.
Short flight was fine, but no entertainment and bathrooms broken.
All went smoothly. Only one delay departing Seattle of around 30 minutes.
We were in 1st class. Haven’t flown 1st class in over 35 years. This was special trip. 30yr anniversary and family travel. Food was good for airline food. Crew was very attentive.i expected easier movie access. Had to use own device. Second leg with Hawaiian airlines was exceptional in every way.
I paid for a window seat and on both flights I was put in the middle seat. Then on my flight to seattle I had to sit next to a passenger with a cat. I'm allergic to cats. So I sneezed, and had a running nose all flight.
Since the flight was delayed, snacks and water were provided.
This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one
Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate
Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.
Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.
The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,
On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.
The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!
I believe that a four-hour trip should have a meal. Delta had none.
Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!
Check in process was terrible. Lady at counter didn’t know what she was doing
Attendants seemed un-engaged and indifferent when asked for assistance.
Overall it was a good flight. The thing I most appreciated was that you eliminated plastic cups and water bottles and stir sticks and had paper cups, wood stir sticks and cans. Plus, I saw that the airline staff were actually keeping the used paper cups separate and unfolding the used cardboard meal boxes and keeping those items separate from the trash. Good for them! This makes me want to support Alaska Airlines and fly Alaska again. Thank for taking this step in working to reduce single use plastics! Kudos!
It was pretty good except there was no food, which was understandable because it was a short flight but I would have liked to at least have a snack; otherwise it was great. Staff/crew, great. Thank you
I was on Alaska and its backup airline. I was scheduled for wheelchair service but ON ONE SHOWED UP. When I asked, desk attendant said they didn’t have any.
As noted above, getting on to the plane was rushed and upsetting since no boarding passes were available to me prior to boarding. Others were in line waiting as well. The flight and experience itself was fine. Very large plane. Two seats near windows; 4 seats in the middle aisles. Good leg room though and comfortable seats.
The trip was fine, however once we reached Seattle, our next flight only had an hour turn-around time and we had to cross the entire Seattle airport, taking three shuttles. Once there, Alaska/Hawaiian Air had still not issued my boarding passes to us and we had to wait at the counter for them. Boarding was already started and at the second to last seating level when we finally got our boarding passes. This was a bit nuts.
I am disappointed with Alaska. They are just like the cheapo airlines, nickle and dimeing us for everything. We now have to pay extra to pick our seats? Really?
I could not use my Hawaiian airlines confirmation number to check in. I figured out on my own that I had to use Alaska airlines confirmation number to check in on the Alaska airlines site. I called Hawaiian airlines and they told me that they could not help me.
Alaska Airlines crew had the empty two people seats but they lied to us and said they can adjust us , so we have to seat apart
Ok but why they need to sell the ear buds?
Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5
Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .
Staff was rude. Didn’t give water for 2 hours. Worst service
Was on time until within 1 hour of flight-how does that happen? Staff very friendly.
I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.
We were given vouchers we couldn’t use with a 5.5 hour delay
it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks
I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.
I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.
leg space better than expected. two washrooms for one plane isn't enough.
Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.
sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.
Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.
What I expected, nickeled and dined and a frontier flight attendant loudly complained about her job and lack of communication as she headed to the gate on her cell phone. Not professional.
As every law enforcement agency I could imagine surrounded the plane and we didn’t disembark for 2 hours and then had to stick around for another hour to go get our personal belongings after leaving them behind and being bused away from the plane, it was scary and inconvenient. We were given no information as to why this was happening. Lack of communication with passengers was disappointing.
After boarding and un-boarding twice over 6+hours, the flight was canceled.
Severe turbulence. Captain never came on to reassure passengers after things settled down.
My first flight was delayed 5 hours. The 2nd flight was canceled til the next day and the never even tried to compensate for it. Worse I was delayed again on the flight the rebooked me on.
Boarding in Orlando was not good. Giant mob at the gate, should have been lines.
Decent clean onboard experience. Okay discount airline experience. Unfortunately, any customer service interactions are difficult and unhelpful. There is no service. Also, a premium seat only gets you premium boarding if you line up first. Once they start general boarding you must go to the back of the line. Not very premium
