Over all it was great. My original flight was canceled but they quickly rebooked me. I was frustrated because I had to cancel my entire plans for the day but all considered, not bad. The crew tried to keep us calm while we sat in the plane for was felt was an hour or so but they could use a bit of a script. The seats were comfortable and I would give it another try.

Over all it was great. My original flight was canceled but they quickly rebooked me. I was frustrated because I had to cancel my entire plans for the day but all considered, not bad. The crew tried to keep us calm while we sat in the plane for was felt was an hour or so but they could use a bit of a script. The seats were comfortable and I would give it another try.

Not able to get boarding pass for domestic connection flight when check in at international airport. I was told I need to get connection flight boarding pass after I entered US. It us very inconvenient.

The gate agents begged us to check our carryons. They BEGGED us, over and over, and said that the flight was completely, totally full, and said that if we don't check our bags, it will cause huge delays. They finally said that "group suchandsuch will be required to check bags!" So I checked mine. Well, the flight wasn't close to being full, and many of the overhead compartments were *empty*! Moreover, my bag was delayed at the carousel, and it wasn't on the carousel that was posted. COME ON, AIRLINE, you can look at the seating for the flight on your computer and decide whether it's really necessary to beg and beg and beg people to go through the hassle of checking their bags! This is annoying as hell and makes me not want to use your crummy airline ever again.

It is a hassle to not have entertainment screens on the backs of the seats.

No headphones provided. No gf food. Only 1 beverage cart run sAN to HNL. Rarely saw crew members

No issues and clear sailing. What a preferred to have sat in one of empty seats other than my assigned seat that would be my only complaint if it was to complain.

Due to plane delays on both legs of my flight home, I had to be rerouted from Santa Rosa to Las Vegas on Skywest and then to DCA on American. SkyWest airlines sat on runway in Las Vegas for 20 minutes waiting for gate to clear. My boarding pass for American that I was given by Alaska was incomplete and the Las Vegas airport lacked signage and departure boards. I barely made my flight bc it was so confusing. American Airlines has a much better wireless connection. I’ll never fly Alaska again. It clearly has problems.

All good. Great food and entertainment when there isn’t any on a one hour flight

The first flight attendant who served refreshments was not pleasant at all. No eye contact, no smile, I used my “please “ and “thank you “ and all but had pretzels thrown at me. Next one far surpassed pleasantries and more like Alaska Air! Good leg room, comfortable seats. Boarding was without flaws. I didn’t order food….

Alaska personnel were excellent especially given the 4 hour flight delay we experienced. The food options post security could be better and are noticeable when one has a long flight delay.

3 hour delay. Had to change plans and was still delayed.

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Delays delays delays. Late taking off, late landing, wait for a gate, etc.

First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

Everything was great except for the in-flight wifi that wasn't working.

It was great! The new boeing has much more space and charging ports!

Flight was on time. Friendly staff and flight was smooth. We Love Southwest.

I had a great flight from Sacramento to San Diego on 2024-09-20 (at 9:00 am). Everything worked well, the crew was pleasant and efficient. Thank you!

Flight delayed two hours , missed connection flight then connection cancelled- horrible experience with hotel

The checking was disaster, the crew wasn't behave well. It took us two hours to check in, after that thr line at the TSA was long, we barely make the flight. Bad airline

I like that if they asked you to checked in a bag at the gate they give you priority to board

Previously flown Hawaiian Airlines on similar routes, I found Alaska Airlines to be noticeably more comfortable. The seats on Alaska Airlines provided better support and cushioning, which made a significant difference on the long flight to the islands. When you’re spending 5-6 hours in the air, seat comfort really matters, and Alaska Airlines delivered where it counts. After comparing both carriers, I’ve decided to book with Alaska Airlines for all my future Hawaii trips. The superior seat comfort alone makes it worth choosing Alaska over Hawaiian Airlines. If you’re planning a trip to Hawaii and prioritizing comfort, I’d recommend giving Alaska Airlines a try. You won’t be disappointed. Highly recommended for Hawaii travel!

One hour waiting time after boarding, but arrived in time. I am satisfied

I understand that both Hawaiian and Alaskan are in the process of merging but I could not get real-time flight info or access my boarding pass on either app

I could not check in ahead of time. Kayak did not give me a proper confirmation number to check in.

You did not have any vegetarians options for the free meal! I do not eat any meat of any kind! I asked the flight attendant and was met with kind of a rude statement like vegetarian? No we don’t have that kind of thing! Did not make me happy but made me feel like why would I want a vegetarian meal! Otherwise a good experience!

Traveling with my 90 year old mother, the boarding process was great, the gate crew was very helpful and friendly. One of the flight attendants was kind enough to assist her to and from the restroom mid-flight and cater to any requests she had. I wish I flew Hawaiian Airlines more often, it was a great trip!

When I was not allowed by Alaska airlines to board due to time and difficulty pre-check the night before and kiosk did not work when I arrived at the airport and then finally told Alaska airlines is where I had to go. Not Hawaiian airlines that they had moved. That's when I was treated with the utmost disrespect by Alaska airlines agent that I was not allowed to board. And that might ticket to return was canceled and I hadn't even left yet when they gave me the option for the next flight to raise my flight price to $300 one way. I bought a $96 round trip ticket and they're trying to gouge me for $600 in addition and canceling my return flight.

Delayed for mechanical and no updates on what was happening and how long the delay might be.

We are too tired and frustrated to comment politely at this point

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

The service and food needs to improve to catch up with other international flights

The flight crew was fantastic! Which the seats had a small TV.

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q

This time my flight was smooth and uneventful. They started boarding even earlier than it was scheduled. I was pleasantly surprised. Thank you!

Boarding was a mess - the agent basically called every group in rapid succession, so there was no organization at all. The economy seats are a joke, and main cabin extra seats were sold out when I purchased my flight. As such, I was locked in the same position for four hours. Being 6’6”, it was impossible to get my bag out from under the seat in front of me, and I couldn’t have used my laptop even if my bag were accessible due to the minuscule seat pitch. Also the wifi was broken. American is a joke - can’t wait until they merge with Spirit.

Cons: "Just seemed chaotic. Plane super late departing. Baggage pick up was a nightmare."
