The Alaska app and website were not fully operational. I had to spend about 15 minutes at the counter doing things that should have been completed online. The agent was very nice and helpful, however.

The Alaska app and website were not fully operational. I had to spend about 15 minutes at the counter doing things that should have been completed online. The agent was very nice and helpful, however.

Staff are helpful and patient. I don’t appreciate the almost 5 hours delay and also the delay of our luggage and being switched from one carousel to another to pick them up.

We waited over an hour for our luggage to arrive at the carousel in Seattle.

Good. They checked my bag FOR FREE so I didnt have to try to hoist it up into the overhead compartment. Also, they served free beverages, which I appreciated.

I ordered the fruit and cheese plate on both outbound and inbound flights, the cheese portion on the inbound flight was half of what it had been on the outbound flight. 🙁

Everything was really good except it was really cold in the plane,

Delayed flight due to mechanical issues. You only serve water or apple juice which is pathetic. To get to connecting flight you need to take a train so dumb. All in all it’s certainly not about the customer is it? You make that perfectly clear. It’s the last time I fly with you no matter how cheap your fares are!

There was no seating at the gate, no where to charge your devices, super crowded. Boarding in group F meant all luggage space was taken when it was time for me to board. The boarding crew was short with everyone and seemed irritated. The luggage space was insufficient, the seat was too small for me (6'4") and very uncomfortable trip. I was in a middle seat between a person snoring the whole trip and a person with very strong body odor. The flight crew was terse and unfriendly, seemed irritated and impatient. Yelled a lot at people with earbuds in, understandable. Finally, we arrived 10 minutes early, only to sit on the tarmac for 20 minutes and wait for a gate. Worst flight experience I've had in years.

Check your emails that you sent me. 9 emails were sent telling me that my flight is Delayed. Each one with a different time 7:10, 7:55, 9:31, 9:09, 9:29, 9:44, 10:00, 9:49, and 10:10. That was how my experience went.

First time flying with any airline that has decent seating. Great experience crew was friendly and the pilot was as well.

Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

I would have liked to arrive on time - not 5 hours late!

It was a perfect flight in all aspects! Both legs!

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.

Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Food from the flight from Atlanta to Santiago was very poor..

Delta flight was on time, seats were comfortable, and crew was nice.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

Flight left early and arrived early. the whole trip was excellent.

Same as ive said before. All airlines and TSA need a massive revamp.

Alaska airline sis usually great. However flying nowadays is so stressful and feels more like an interrogation rather than a fun part of the vacation experience. From the TSA to the cramped seating it feels like i am entering a concentration camp having my picture taken via TSA and being forced to have my body scanned. Then we are forced to sit in beyond cramped conditions where our knees are crushed into the back of the seat in front of us with almost no movement possible constantly being reminded to put our seats forward when we want to alleviate the horrendous pain of our knees being shoved into hard plastic. My knees looked like i had kneeled on gravel for 2 days straight after flying for a total of 14 hours for my roundtrip. I keep hearing from our elders about the jopys of flying in the 70s and 80s but now it feels like the joy has been removed as a means of acquiring more financial gain by the airlines. Not to mention that my flight via hawaiin airlines was delayed so long that i had to miss my connecting flight which then forced me to miss another day of work and the only recourse i had was a wonderful conversation with a lady via Alaskan Airlines when she got me a new flight the next day due to the delay. She was very pleasant and helpful. She got me onto a nother flight the following day but when i have to travel 2 hours from springfield Illinois to st louis it was a huge hassle having the delay in the first place. Not even the tiniest bit of compensation was offered either. Not a voucher, not a free meal, not a slightly better seat, just a reschedule when in no way was the delay or the missing of the connecting flight my fault. I want to reiterate that Alaska Airlines is really one of the best airlines overall. I fully understand they dont control the TSA, but it does effect the overall experience when TSA is making it feel like we are going through a re-education camp with rather strange videos playing on the walls the entire way through Security. With that said, Alaska should take cosnideration from years of past and make the flying experience fun again. I understand profit is important, but if just ONE airline made flying like it used to be 40 years ago and stopped making it such a money-driven experience, then i, along with many others would choose to fly more often. We see the smaller soda cans and we laugh, we see the tiny snacks and scoff, we see the ridiculous wifi costs and choose to not pay for it because we download our own prior to flying. Why not get everyone to use the wifi by making it like 2 bucks rather than 8 bucks? Make a much larger first class area with slightly lower costs so it doesn't feel like we are mere peons boarding a cattle car? Create some more leg room and watch how fast people are clamoring for your airline over others. Not one airline is actually catering to the general public, if they did, they would see so many people seeking out their airlines above all others and it is just that simple.

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.

If I knew I would be on Alaska Airlines flying back, I never would have bought the ticket. My flight kept getting delayed and Alaska always seems to be late which is why I don’t fly on them.

Good. They changed our gate very late and then when we landed, we had to wait 20 minutes to get off the airplane because another plane was in a slot.

Flight was canceled with no voucher of any kind and next available flight was two days later.

It was very pleasant. The staff and crew are very polite.

On time. Alaska upgraded seat comfort with memory foam seat covers with head rests

the people at the counter, NEED TO BE MORE HELPFUL. we had three suitcases to check in and we were not trying to be an INCONVENIENCE TO YOUR clerks. but she was not helpful and made our trip back home memorable but not IN A GOOD WAY. Sadly to say, you guys need to teach to be and to go above and beyond to help THE CUSTOMER BY ANY MEANS POSSIBLE. they need to leave aside whatever they are going thru in their lives, THEIR WORK DEMANDS THAT OF THEM, IF NOT THEY ARE NOT IN THE JOB THEY SUPPOSED TO.

Not happy that I booked a flight and after I booked it, you guys changed it when I could’ve got another flight and got to my destination on time then got sick and was not able to make the flight and try to make arrangements to reschedule my flight, but because it was a basic flight I wasn’t able to reschedule it without it costing more money so no, I will not be using your guises airline due to the fact that you guys haven’t been pleasing to me from the start thank you
