We waited over an hour for our luggage to arrive at the carousel in Seattle.

We waited over an hour for our luggage to arrive at the carousel in Seattle.

The plane was delayed a bit. It wasn't a huge problem though, as we were heading back home.

Flight was great. Boarding was crazy because another flight was boarding late next to ours so everyone was standing and in the way.

Comfortable seat, a little delay, very informative. Love Wi-Fi

very good but no blankets for overnight flight or tv screens…

Good. They checked my bag FOR FREE so I didnt have to try to hoist it up into the overhead compartment. Also, they served free beverages, which I appreciated.

late take off - which they blamed on ATC 1000 times. Fake news that there was no room overhead for carry-ons. Seat space was so tiny I could barely drink my coffee. Cabin was freezing cold. Seat was hard. Zero in-flight entertainment. Only good thing was we arrived on time. Not a good experience!

I ordered the fruit and cheese plate on both outbound and inbound flights, the cheese portion on the inbound flight was half of what it had been on the outbound flight. 🙁

In GEG I arrived at 0930 for a 1600 flight. Alaska had a rule that you could not check your bags until 4 hours before flight time. I was forced to sit in a chilly lobby for hours. I had access to a bathroom, but could not go into terminal for food and drink. Boarding and flight OK

Everything was really good except it was really cold in the plane,

It was a perfect flight in all aspects! Both legs!

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

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.

Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

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.

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

Flight was canceled with no voucher of any kind and next available flight was two days later.

It was very pleasant. The staff and crew are very polite.

On time. Alaska upgraded seat comfort with memory foam seat covers with head rests

There were several delays and we were stressed about making our connection. The announcements for boarding were hard to hear or understand. The seating was uncomfortable for a 6 hour flight.

When I was not allowed by Alaska airlines to board due to time and difficulty pre-check the night before and kiosk did not work when I arrived at the airport and then finally told Alaska airlines is where I had to go. Not Hawaiian airlines that they had moved. That's when I was treated with the utmost disrespect by Alaska airlines agent that I was not allowed to board. And that might ticket to return was canceled and I hadn't even left yet when they gave me the option for the next flight to raise my flight price to $300 one way. I bought a $96 round trip ticket and they're trying to gouge me for $600 in addition and canceling my return flight.

Despite two calls as well as a chat on the website, Alaska would not add my TSA number to my reservation. The flight was switched from Hawaiian to Alaska which caused them to mess this up in the first place

The departure gate was changed from C1 to B18 but it was never announced at the C1 gate nor did I receive any email or text message or phone call about the gate change. I was in a window seat. In the other two seats next to me were Mr. Rotund and Ms. Rotunda, a youngish couple. Just the two of them should have booked three seats. I was smashed up against the wall and window for five hours. Overall, I'd say my flight sucked. Wouldn't you?

I couldn't get checked in 24 hours before either leg of my flight. I tried both my Alaska and Hawaiian codes on both apps.

We moved from the international terminal to a new location. I think there are still some bugs to work out . We didn’t receive check in notification and had to scramble to find it but i think it will work out

Not so good. The takeoff was aborted after reaching 100 knots due to a problem with the front tires. I do commend the pilot for a quick decision and preventing a potential disaster. We returned to the gate to put fresh tires on the front. Our flight was delayed for over 3 hours. The rest of the flight was okay. We were reimbursed by Hawaiian Airlines for only $50. Not too generous

Good experience except for the drunk woman who was with a child. Sad

Too many time late and postponed No electrical power for my electric devices

Spirit is by far the worst airline to travel with, period. Seats are cardboard, flight attendants need anger management and if you ask for water, you’re basically a criminal. I don’t care how much it costs but I will travel with an airline who actually cares about their customers. Oh and one more thing, the next time your gate agent puts his foot on someone’s baggage's scale, I hope they get what’s coming next, a viral video of your scams. You suck Spirit, do better.

I mean, it’s Spirit. But it was frustrating to have our flight canceled, get bumped to a later flight, and then Spirit was unwilling to check our bag until 4 hours before our flight… tell us we could not sit in the waiting area’s chairs… and really negative experience getting checked in and dropping the bag.

terrible service, no room for a dog underfoot, a broken chair that is impossible to sit on and all this costs a lot of money

It was fast but uncomfortable seats. Had to pay a bit extra not sure why? Maybe in selection of all my 4 tix together ? Just knew I had a balance before getting boarding pass online when departing from satx ? And flight was delayed..

Last minute 2-3 hr delay in flight schedule; no explanation Unexpected extra $52 charge What's the benefit of choosing a cheap airline if you trick people last minute and force them to pay extra last minute? Did not appreciate being cornered.

Seats are uncomfortable and too close together. Also, you missed my connection in Vegas on the way back and I ended up sleeping in the airport, flying back to Burbank instead of LAX and I got home 12 hours late.

Surprising everything went well. Nice attendants and fast getting on and off the plane. Overall, was happy with the experience.

Non-professional acting crew, Very uncomfortable seats…!! Very bad pricing with all the add-ons for seat choice, luggage fees, etc….soon you’ll charge extra for oxygen. The ticket price means Nothing because in the end, the actual amount i paid, i could have and will in the future continue to fly on a real airline…
