On time, smooth take off and landing, efficient boarding. Gate staff excellent, stewardess grumpy, but civil enough.

On time, smooth take off and landing, efficient boarding. Gate staff excellent, stewardess grumpy, but civil enough.

No WiFi available. It was too late to order food also. Guy next to me was huge (not fat) so had his shoulder & thigh next to me the whole way. Plane was delayed leaving PDX due to 8 other planes waiting. Not my best Alaska airlines flight.

Check in, they should have told me that upon arrival i needed to exit the secure area and re-check in with Eva Air. I wasn't sure what to do upon arrival at S.F.

Flight last minute delayed 2 hours for crew calling out sick

Laney was very helpful. I am computer illiterate. She helped me obtain a boarding pass and preferred seat. She was warm, friendly, helpful, and smiled. I was impressed.

Although both planes (flights) had mechanical issue delaying both of my flights, the crew members handled everything with ease. Both flights had the smoothest take off and landing. I opted to upgrade my seat to first class and really lucked out getting the seat at the very front of the plane. Awesome treat to myself. I really enjoyed my flight.

The staff from check-in counter to the flight crew were great. Flight was right on schedule. 10/10

Changed flight from San Fran to Seattle Then with a Delayed takeoff barely made my connection Waited over an hour for luggage 😜

Very comfortable - thanks. Only small criticism was the delay in disembarking caused by the passengers in the front two rows chatting to the cabin crew.

Probably one of the best flights I’ve had! From entering the airport, to boarding to landing.

It was not a good experience. When I went to check-in one of Alaska's employees told me I had to check-in with Hawaiian Airlines, which was on the opposite side of the airport. I made my way over and when I got to Hawaiian Airlines they told me I was in the wrong place. The employee saw the look of defeat in my face and was able to get someone to check me in and text me my boarding pass. I had to make my way all the way back to the other side of the airport and barely made my flight. I think it would be very helpful for employees to be more informed with these Hawaiian flights that are operated by Alaska so they are not rerouting people to the wrong terminals. Also, clear signage in the check-in area.

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.

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.

I DID NOT GO TO HAWAII ON HAWAIIAN AIRLINES. YOU DID NOT INFORM ME THAT BY CHOOSING BASIC ECONOMY, I MIGHT BE REQUIRED TO FLY STANDBY. I AM ELDERLY AS WAS MY COMPANION WHO IS ALSO SEVERELY DISABLED AND THERE WOULD BE NO WAY WE COULD TRAVEL ON STANDBY. THEY TOLD ME THAT ALL OF THE BASIC ECONOMY SEATS HAD BEEN SELECTED BY OTHER PASSENGERS AND WE HAD TO PAY AN ADDITIONAL $942 TO GET A SECURED SEAT ON THE PLAN AND, IN SPITE OF THE ADDITIONAL COST, WE WERE NOT ALLOW US TO AMEND OUR TRAVEL PLANS TO EXTEND OUR VACATION. ULTIMATELY, THE FLIGHT WAS DELAYED. WE WERE OFFERED A REFUND IF WE CANCELED OUR TRIP ALTOGETHER WHICH WE DID. IT IS YOUR DUTY TO INFORM YOUR CUSTOMERS OF THE POTENTIAL PROBLEMS THEY MAY FACE, AND YOU DID NOT DO SO. I WILL NOT UTILIZE YOUR SERVICES EVER AGAIN.

Half of my family members didn’t make it because they involuntary bumped off . And their seats where given away

Hawaiian and Alaska are at opposite ends of the Seattle airport. Apparently, during this time of transition through their merger, only people flying to Hawaii should go to the Hawaiian desk. So, I had to carry my luggage the entire length of the airport. Alaska's desks were sort of a temporary set up behind a wall, and even after all this, they (Alaska) had a great deal of difficulty confirming that I was on the flight, or that I had paid my checked bag fee. Now, they did try to compensate for all this confusion. There was an impressive number of agents, actively engaging and working with customers - not just standing behind the counter, but going out to them with pads in hand. It took some time, but I was squared away, and was apparently upgraded to a business class seat with lots of legroom (much appreciated). I was told this transition would last till August.

Really enjoyed their food treats, staff was friendly and they kept our seats together, check in was excellent, boarding passes uploaded to my wallet! I would definitely recommend Hawaiian airlines to friends and family! 🌺

I booked through Hawaiian which was supposed to have merged with Alaskan but offered free checked bags and said there would be seat selection at the airport. This was not honored by Alaskan Airlines and they even went out of their way to say “we are not Hawaiian and Hawaiian cannot pick seats on our airline ”. They told us that we could not change seats and that all tickets booked through Hawaiian were “saver fares”. The staff was rude and said that we would be helped last after they take care of the customers that booked through Alaskan. Once we got on the flight in our middle seats they played a message that said they have merged with Hawaiian and you can book on either website which would have been funny if we were not so uncomfortable. All in all it was a terrible experience and I do not recommend that anyone fly Alaskan unless they absolutely have to.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

United out of SFO is having issues with catering so none of our meals were loaded on the plane and no offer of compensation for our tickets purchased was offered.

A bit rush for transit. Food and entertainment are not available

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Boarding was a breeze, however, two of the flights that I boarded with Spirit did not have Wi-Fi available.

Very good. Nothing more or less than expected. No complaints.

My experience with the spirit as a first time it was OK, but the seats need a little cushion, the problem I had the most impacted me was when checking in the scales were so off and wrong. It will tell that you would have more weight, which was not true. The scale was say that it had Thirty Eight Pounds, when get in the labels when we send the luggage into the band. It says that it was overweight. I really really dislike that because the scales are not accurate. If I use Spirit and I have that issue again. That will be my last time flying with the spirit, even though I like so much to service the planes, and everything else

hahaha we are delayed for one hour plus.. but thx we arrived San Diego safe

Worst airline ever! The guy weighing my bag had his foot on the metal plate and when I called him out on it, I got this stupid little smirk. La is a scam and so is Spirit Airlines. All the flight attendants looked like they hated our flight just as much as we did.

Unclear pricing; ended up being charged an extra $52 just to get onboard

Spirit is awful. Too expensive for what you get. Stop nickel and diming.

would be great to get basic water, soda at least and stop charging for carry ons

Your crew is a representation of your Standards and Values. The crew from Seattle to LAX, was very disappointing. The crew was more interested in hanging out at the lobby area. Talking, laughing loudly and eating all the snacks. They did not do regular rounds to see if customers needed anything. This was a huge disappointment. I will no longer be flying with your airlines moving forward.

- flight attendants not very friendly. - Paid for WiFi and plane didn’t have it working , never got a refund.

They canceled flight. Hard to believe there was even a plane incoming for us to get on

The worst. We never made our connection and they did absolutely nothing to help us at the airport.

Our flight was cancelled. They could do nothing to help us get another flight that was timely. Because the first leg was cancelled we were unable to get to our connection. We had to book on an entirely different airline for today. So we spent more money, lost a day of vacation and will never fly Frontier again, so the 'we are sorry, here is $100 credit' is a joke since we won't be flying on Frontier.

No way to get boarding pass on my phone. In order to print the bag ticket a boarding pass is needed. Asked the agent to print me one, they said they typically do not due this as its so much work. I showed the email confirmation and I asked how i could do it my self the agent replied he did not know as there was no link. The flight was delayed due to an attendant forgetting to come to work. On the flight no drinks were offered only for purchase meals.

Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead

Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.
