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

A solidly good experience, but would’ve appreciated more communication with regards to travel delays.

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.

They changed our flight from a one stop 3 hour layover to a non-stop. Saved us hours and got us there sooner.

Departing flight to San Diego was delayed. Return flight from SD to SBP was delayed. Not terrible but not ideal

I was happy with the flight. It was too short for food and beverage service. (no problem) We left SLO on time and arrived in San Diego on schedule.

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 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.

First time in a long time and look forward to many more

Service was professional and quick. Premium economy seat was comfortable given the class

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Was a pain having to leave the plane and reboard but glad the plane was fixed

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

For a 22 minute flight all you expect is for it to be safe and comfortable

Boarding took a long time for a couple of flights. We arrived at our final destination an hour late. Others missed their connecting flight. We had no time to eat between flights. My checked in bag was delayed because it was in another flight. At least they gave us a voucher because of that. The staff was very kind.

Lost connnection had to stayON in Chicago Was a mess

Booked economy through United - air canada treated it as standby and was almost refused boarding.

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."
