Check in early, give yourself a bit of time, and enjoy the flight. Lihue has a super small airport, so not much going on there.

The crew was very kind and made going to Hawaii relaxing and fun to look forward to! Thank you Southwest for a pleasant flight!

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.

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.

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.

Much better than the.last. flight on SW on Thanksgiving day

Unfortunately it was not a good experience. There was a rude stewardess.

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.

Boarding was well explained and smooth. The flight was short, so there was no time for snacks. They did offer water or juice, though.

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.

Price was right. Add power to the seats, television, larger plane to accommodate a long flight to improve mental health and overall comfort for a 5 hour flight.

Delayed flight caused us to abandon bags in hnl or miss our United flight home. Awful

You can standby to get on earlier flight if the seat is open.

Short trip from Honolulu to Kauai. Not a major issue. Only concern was the drop off of the luggage for departure. Only one person handling all of the passengers. She was busting her butt.

Should have been forthcoming for reason for delay. Should have been able to check in for seat I'd like.

It was fine. It was a 30 minute flight so there was water or fruit juice and no food. Which was totally fine. The check in, gate and flight crew were all excellent.

Once again, Hawaiian Airlines upon checking in for our return flight, told us that we hadn’t paid for our extra comfort seats. This had happened on our incoming flight as well. Hawaiian Airlines had changed our flight and put us in standard seats. I sent them confirmation emails and receipts showing that I had paid for extra comfort seats and they ignored me and refused to accept my proof of payment. I ended up having to pay for our extra comfort seats again. On our return flight, once again, we were told we hadn’t paid for our extra comfort seats, which we had. I argued until a supervisor was summoned and researched further in their system and found that we had paid for them. If I hadn’t insisted, we would’ve been forced to buy our seats again or be assigned a standard seat. This kind of Customer Service is totally unacceptable. I would never use Hawaiian Airlines again if I have a choice.

My experience from Lihue Airport was the “Flight Experience from Hell!” First, I was pulled aside by the Lihue TSA and searched thoroughly! Not once, but twice I was molested by 5 different TSA agents using some sort of smear cloth testing to see if I had been exposed to something dangerous! I can’t tell you what because they never gave me an explanation by the end of a near delaying incident of boarding my plane. More importantly, I was generously provided an airport wheel chair and personal porter because of my health condition. TSA even took your wheelchair apart! What’s up with that? I’m near 75, caucasian, never been arrested for anything, don’t do drugs or alcohol, and patiently and politely abided to their instructions for a full damn 20 minutes! Awful and humiliating experience especially when two different agents literally groped my testicles and crack of my butt! Then they lost the cap to my inhaler. When I got to my destination, a whole bottle of prescribed pills were emptied because of them not tightening the cap back on! Total BS and unprofessional by the lot of them! The short flight to my connecting flight to the mainland on Maui fortunately was uneventful. However the Hawaiian aircraft to San Jose was one of the worst flights I’ve ever experienced without crashing. I believe it was a 330 Neo. May I ask, why did you put three more rows of seats in the damn plane since I last flew on a Hawaiian aircraft? I had absolutely NO legroom compared to the last time I flew with you. And I’ve done a few Hawaii/mainland trips, even a RT to New Zealand before. Then, the icing on the cake was a couple with a one year old baby that literally cried and screamed for all but 15 minutes of the 5 hour flight to San Jose! Further, I couldn’t move my seat back even a millimeter because a car seat was placed from their window seat to the back of my seat! My Hawaiian flight was a freaking nightmare and fortunately will be flying back to Lihue direct with Alaska!

Tickets we booked together in January became two different connecting flights. VERY PISSED a about this and a terrible start to our bucket list vacation

I needed more space to sleep on an overnight flight.

Wonderful respectful staff for a short flight late at night...lots of considerations all met!

Omg the disaster at the security was on another level! “Go to this end, sorry closed now, go to that end”. Ridiculous! This took over an hour! As far as the airline was concerned although I booked nearly a year ago I couldn’t get my bag tag - stand in another 15 minute line or my seat on Hawaiian Airlines- 5 more minutes! Then my TSA status was denied. Like what the heck! Makes a person not want to travel with this amount of incompetence

I always love flying Hawaii and I have nothing to add

Everything was great and smooth. Given the short flight there was no entertainment but the rating does not give this option. My first flight with Hawaiian was a success all around.

Very accommodating on flight changes when something came up. Definitely felt a notch above other airlines.

Love you guys are so friendly and kind and wonderful

Hawaiian airlines has awful customer service. Told me to keep a flight I wasn’t boarding, instead of rebooking me under two separate reservations, which caused my whole reservation to be canceled. Major issues with leadership and management. The staff at Hilo was reluctant to give me a refund, so I had to by a first class ticket in order to get on a flight the same time as my partner. The blame was pointed at me without sincere apology until the supervisor came out, who also apparently had no authority to refund me. Still waiting on correspondence from the airline days later.

It’s great, I’ve always fly & ride with Hawaiian Airlines going Inter island or to the mainland.

Hawaiian Airlines staff is always professional & quick & easy check in & boarding process

Bar code for checking luggage and boarding pass didn't work. Had to stand in long customer service line. Passengers at Oahu should be aware the Terminal for Hawaiian Air requires travel by shuttle. Budget an extra 20-30 minutes to get from the main terminal to the remote terminal.

Checking baggage at Honolulu was a real mess. No signs directing where to go.
