Airline reviews

Great. I did have a little issue getting into the Lounge, which is likely more an American Airlines issue. I did not carry my physical AAdvantage Executive credit card with me on this trip, which Admirals Club membership is a part of the benefits of having this card. The instructions on the AA website and the Citi cards website make it seem like you don't need the physical card, as both sites state you can enter with your boarding pass and driver's license. But both lounges said you were required to present the physical card (and not the digital version, via Apple Pay), as only the physical card says "Admirals Club" on the back.I also do not have a physical Admirals Club membership card, so while both lounges eventually let me in, both denied me entrance initially for this reason.

Everything from the time I booked my flight through to the end when I got home was smooth and wonderful. Service was great, the flight attendants were attentive and there were no outstanding delays.

Delayed and no entertainment? I also forgot my headphones and immediately reported it and have not heard back yet.

The crew was very friendly. Boarding was quick and efficient.

we waited for 50 minutes to check a bag and missed a flight. do better.

The flight crew was very professional and pleasant. Our flight was delayed 3 hours, but Kayak informed me in advance

Before I even boarded this old white man , a fat Samoan lady, and a short brown guy were at the desk. They asked if we could have 15 volunteers to get free checked bags cause it was a full flight. I waited in line, I got up to the short brown guy and he asked for my boarding pass and I showed him, he said that he can’t check my bag because I wasn’t given a seat yet. So he had me go to the next line with the old white guy, but before I switched lines I asked him, well if I go to that line, will I be able to check my bag so I waited in line and he said yeah, it doesn’t matter , I’m good. So I switch lines and wait in the line of the old white man, with every guest before me he was very sweet , making small talk, smiling and had great eye contact( all of the people he was talking to was white) I come up and he doesn’t look at me , then says I’ll be right with you, I wait for him to initiate and when he does he’s like what’s up? I was like the man next to you told me I needed to get checked in before I can check my bag. He’s like what’s your last name and I say Valenzuela , and he said we’re not there yet, all while not smiling, no eye contact like he was with the other guests. He said we’re will call you when I get to you. So I go sit down and I’m sitting down for less than a minute and he calls me and someone else. I go up and say Valenzuela and he’s like who are you and I’m like Valenzuela , he’s like hmm and says don’t go anywhere and calls someone else. I finally get my seat and I go back to the short brown man and ask if I can check my bag and he said there isn’t any room available and I was like? Wait you told me and then the fat Samoan lady said yeah we don’t need anymore bags thank you. I was dumbfounded and just walked away. So rude. Terrible experience and terrible communication on their end.

The flight was delayed, but once it arrived everything moved right along.

Great airline. Sat next to a really big person tho

I always choose Alaska when I can. Every thing seems to run more efficiently with them.

I liked the Starlink WiFi but didn't like how they said they were the only airline to offer a free meal and it turns out to be just a standalone sandwich and then charge for snacks to go with it. Rather have the free snacks like Southwest, but have the option to purchase a decent meal for a 5+ hour flight.

I like Hawaiian, it was great that they had good internet connection across the Pacific Ocean, thanks to Star Link satellites. The seating was comfortable, ( I was in economy ). Maybe I missed it, but I only got offered a beverage once. It was a nonstop flight KOA to SMF. I would take it again next time I go that way.

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!

I received several emails about my 3:10 flight. When I showed up to the airport at 12:30 to check my bags I was told the flight was actually at 1 pm. They grudgingly rebooked me for a flight at 5:22 to Vegas to get a connecting to LAX. I did find the gate for my original 3:10 flight but they were booked. I proceeded to receive status updates and gate change information for the 3:10 flight, even though I was apparently never supposed to be on that flight

The crew was EXTREMELY helpful And sweet and the flight was smooth!

The Kayak confirmation number did not work for checking in the day before. I checked in at 8.30 using my ticket number. When I arrived at the airport, I was informed that the flight was overbooked, and since I had checked in late, I did not have a seat. The Next flight was not until ten PM. I called my wife, who had been taking care of our kids all weekend, and she was upset, calling me a liar and telling me to stay in SD. It turned my weekend getaway into a nightmare! I blame the Kayak website and will not book flights using your app in the future.

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

Flying with Hawaiian Airlines is a treat! They have the best crew, food and drinks! I’ve always enjoyed flying with Hawaiian Airlines and will continue to use them!

Amazing all female crew, including the pilot. Great flight attendants and smooth trip. Food was good. Boarding the plane from back to front would have made things significantly smoother. Took forever to wait for people to clear the alley. A little extra leg room would be nice also. Please thank your flight crew!

We decided to take our mom on vacation but we were worried how well she will do on the flight, she's a senior and required special accommodations such as transport chair since she can't stand for long periods. To our surprise my whole family was given priority boarding, my mom was given chair, we were not standing in line and were given seats in good area next to our mom. A+ experience!

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Flight arrived 30 min early and bag was waiting at the baggage pickup. United Club HNL was one of the nicest in the system

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Flight was late - I was downgraded from first class to coach

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

7 hours delayed due to operational issues on United’s end. Basically laziness.
