The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

The first time I flew in the extra legroom section. It was difficult to notice a difference. I had bad luck with my neighbors. The crew was okay. Southwest has reduced the live TV options.

No gluten free snacks. Seats felt worn or bare bones even though it was a new 737 MAX 8.

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

Our flight to Oakland was great bc the plane was new but it was delayed by 15min not bad at all. Over all it was an 8/10

Boarding was quick. The flight itself was good. However, no charging ports for cell phones. Also, the food provided was just a few snacks. For a 5-hr flight, I would expect at least a sandwich.

The flight was very short, 45 mins, therefore no snacks/drinks were provided; there should be a NA option for food and entertainment survey questions. Also, there were no charging ports onboard for cell phones. My experience was overall positive.

I love the fact that Southwest airlines has a direct flight from Honolulu to Las Vegas and Las Vegas to Honolulu. The only downside was flying on Southwest is they do not provide meals even if they charged you they do not provide meals. They do provide a free snack that consists of chips pretzels cheese and a cookie. They do serve free drink and if you book the premium flight then you get your choice of an alcoholic beverage. The seats are small so if you are not traveling with three people plan on someone sitting next to you.

The flight in it self was good. The delays looking for pilots was unexpected.

I love the flight ✈️ Hawaiian Airlines. All stuffs are fantastic members ♡ sweet hearts and families warm welcome 🙏 I have milage of Hawaiian Airlines members so get points .also I booked kayak agent got cheap price ! I satisfied flight with Hawaiian Airlines ♡ thank you

Good, but because I fly internationally I found the food and service lousy compared to European standards. You should include a regular small mean (and not a lousy sandwich) and ear phones. People who travel from Europe are not aware of limited services.

It was not clear the check in shd be at Hawaiian Terminal 1. I got dropped off at Alaska Terminal 2. I did the long walk from terminal 2 to 1. Fortunately I didn’t have a check in bag.

Hawaiian Airlines, like most US-based ones, constantly provide sub-par service and pack their planes to the max with all kinds of last-minute-purchase schemes. As a result, it makes every flight so uncomfortable and generates high health risk for its passengers. In one word, GREED rules the day!

I flew from San Francisco to Honolulu on Hawaiian Airlines. The flight was operated by Alaska Airlines. Everything was fantastic. On the return flight from Honolulu to San Francisco, boarding was chaotic. They called each boarding group 1 through 6 very quickly, and everyone just ran and got in a very long line. There was no enforcement of boarding groups. Carry-on rules were not followed, and by the time I boarded the plane, there was barely any overhead space. I was boarding group 4. The crew was very professional, and the Hawaiian Airlines terminal in Honolulu was beautiful. I wish the rest of Honolulu Airport looked like the Hawaiian Airlines Terminal.

Always delayed, inadequate availability of room for baggage but the crew were good & approachable.

It would have been perfect if it had not been the fact that departure was delayed.

The flight overall was mediocre for me. But the point is that it got us to our destination safely.

Mediocre is best way to describe. Bare bones narrow seats, Dirty pulldown tray, unfriendly cabin crew who were in a hurry to serve tiny drinks and tiny snacks. (Compared to much better Hawaiian Airlines experience, .. no comparison!)

My flight was on schedule, ground crew looks overworked, flight crew was great but refreshments could be better. The plane was clean and fairly new. Seats were comfortable but leg room was tight.

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

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.

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!

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!

Ok but why they need to sell the ear buds?

I loved flying Hawaiian Air! We didn’t pay to sit together, but we were able to anyway. They had usb charging ports and even outlets in some seats. They served a hot sandwich that was not very good, but we were still pleasantly surprised. The staff was very nice. The seats really made my booty hurt but maybe I’m just not used to sitting so long. Also, the AC was really cold even though I was wearing pants, a hoodie, and a light blanket.

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!

The return flight was 1.5 hours behind. Also some passengers lost their luggage or was delayed.

Kayak reserved return seating for me but did not book it. I paid $115 extra and my seat was not reserved.

More movie and tv show selections. Maybe more music selections as well. The food was not great on that flight. On a longer flight like that one, it would have been nice to be offered another drink, even if it was just water.

Excellent flight. On time. Great staff. Clean and crisp cabin.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Packed in plane small uncomfortable seats elbow to elbow nobody wants to be in that situation for the money they paid

Horrible service no Wi-Fi connection on both leg of the flight and they are refusing to fix bad service

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

The flight was comfortable with the exit row and great service

1. when we went to check in, our 2 first class seats had been CANCELED and the flight was sold out. This was done without our prior knowledge. It was all we could do to restore one first class seat for my wife and I flew economy. 2, Our flight home was scheduled to leave at 10:30 pm. Due to tsunami warnings, the roads were closed and our flight status was uncertain as to whether it would leave as scheduled. It was announced that it would now leave at 11:20 pm and the roads were now open since the tsunami had come and gone. We made a mad dash to the airport and checked in. Delays were announced at 12:30 pm, 1:30 am, 2:30 am and at 3:30 am it was canceled. Since this was a flight due to natural (tsunami) causes, there was no compensation. We were told to return at 1:00 pm the next day and our baggage would be kept on the plane since the same plane was going to leave at 1:00 pm. We had to return to our hotel for the rest of the night. The same plane did not leave at 1:00 pm and our baggage was gone! All in all, it was a miserable performance by UA. Information was hard to obtain and no one knew what was going on and what was going to happen. Hundreds of passengers slept on the floor, chairs, etc. No food and no water was made available to the passengers. It was a situation where UA could care less what was going on. As a one million mile flyer, I had not experienced anything like this before and it was hugely disappointing!

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.

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.

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
