Red eye from San Diego. Temperature of the cabin was way too warm and the air duct flowed very little air.

Red eye from San Diego. Temperature of the cabin was way too warm and the air duct flowed very little air.

Great job Southwest! My family doesn't fly often but we felt safe the whole time.

Comfortable. Easy. No problems. Just wish they had gf options for snacks.

The charges were ridiculous for an hour flight and the turbulence was very scary.

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.

No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.

There was over a 9 hour delay for one thing after another. A toilet problem, they had to change the brakes, they had to refuel, three pilots times out, etc. We had to sit on the plane at the gate for over 5 hours with no air.

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

Now that Spirit is not around Alaska took over the title of cheap and worse airlines with high prices for garbage cheap planes. Seats recline the entire 2”. What’s the purpose? Just make the stationary. Crew is on steroids. Food is like McDonald’s happy meal. Only happy in the name rest is garbage

See previous. It was the flight from Honolulu to Kapalua that was cancelled.

Our flight time was drastically changed which caused us to lose a day of vacation

Very bad, terrible food and late by 2 hours. Then no to open aircraft doors

Only problem my credit card had over three pending credit card charges for luggages. I hope these charges do not post. I have already contacted my credit card companies.

Crews ADA compliance ecellent. Sensitive and kind observation involving several passengers on plane Plane clean and fresh includsing lavatories

You sold me a $230 seat upgrade. But it was exactly the same seat as the $89 upgrade. The bait and switch seems to have become common practice.

The crew was wonderful! They were friendly and funny. The plane was clean.

Comfortable seat, plenty of leg room which is so rare, overhead bin comfortably accommodated my carry-on bag. Deli box was tasty, service was good, bathrooms were clean. Uneventful flight, which I appreciate. Departed on time and landed early.

Honestly, there was not much they could do. Due to wind, the flight was delayed for several hours because we had to be diverted to San Jose where we needed to refuel before departing to Hawaii. Wish they had offered some snacks during the delays/diversion because we had to wait such a long time to finally get our food served during the flight after leaving California.
