The flight attendant for first class was excellent. Very attentive to the needs of the passengers The time scheduled for the connection flight on to Kona was too short and we missed that flight. But another flight was only an hour later. But it should have been scheduled that was in the first place.

The flight attendant for first class was excellent. Very attentive to the needs of the passengers The time scheduled for the connection flight on to Kona was too short and we missed that flight. But another flight was only an hour later. But it should have been scheduled that was in the first place.

The problem was going through San Diego, a trip that's become a new development.

No complimentary snacks or food. Had to buy drinks and food.

in-flight wifi was not working well. also the cabin temperature was a bit hot.

I wasn’t able to check in prior to arriving at the airport, I was told by the agent I may not get a seat on the plane as others were waiting for seats, I sat there for 2 hours before being assigned a seat, very stressful. The plane was delayed. Overall not a great travel experience for a 44 minute flight.

Larger seats and more room would elevate the experience. Otherwise, it was good!

Check in went pretty well and you didn't lose my bag. After I got a drink from the drink cart they charged me for it, and at the crazy overpriced airport rates. Never had that happen before, is that an american thing? what madness.

I was delayed several times. Missed a very important event. The airline only provided a $12 voucher after being delayed 3 times.

Wish I got An email stating that I needed to check in at hawaiian even if I made my ticket thru alaska. I had to walk to terminal A from Terminal B.

It was Okay. I do appreciate the flight being on time and the happy crew.

Despite paying for an ‘upgraded’ seat in row 1, I had to put my luggage in the middle of the plane. Snacks were bleh and seat was small and uncomfortable and I am not large. Attendants were fine but not super helpful. Plane just seemed outdated.

Delayed flight, lack of information, boarding process is a mess as is the carryon luggage causing issues when leaving the plane….just a poor experience.

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

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

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.

Forget beverage, they didn't even have water for half the passangers?

Flight was not full! Had a whole row to myself.

Wifi didn’t work, no service, seats are hard as rocks

Had to deplane 2 x due to problems with plane. Delayed over 6 hours ans was given a $12 food credit which barely oaud for anything and limited to wear incoukd redeem.

Seats were not bad enough and uncomfortable good legroom in the emergency exit row we were in, but we were forbidden to hold my grandson on my lap for a little while, and the stewardess passed us saying it was against regulations which makes little or no sense when you’re 36,000 feet. The food snacks were really bad. Tasteless tasted like wallpaper, but we’re supposed to be protein bars, and the announcements were all completely incoherent because of the noise of the airplane and the lowness and crackly nature of the PA system.. this was disgraceful. No one in our party could understand a word of what the captain or the flight attendant were saying —not a word! The landing was a little hairy in a pretty stiff crosswind -we bounced before the plane stabilized on the runway

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

I didn’t not like that I could not select my seat and ended up with the worse seat.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska
