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.

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.

In both halves of the trip (going and returning) there were problems. Not exactly Alaska's fault, but still really difficult. Outgoing flight was canceled and rebooked twice due to a total ground stop of all Alaska's flights. This required me to change airports with minimal notice and I almost missed my flight transferring to the other airport (which was roughly an hour and a half away). On the return, the first leg was delayed by an hour, and the second leg was delayed by nearly 3 hours. This was a rough set of flights and the communication about all of these changes was minimal. Crew did their best however, so no fault there. Other thing to remember is there is no food on Alaska flights unless you pre-order. Take that into account when you choose airlines.

My flight was canceled because of an IT outage, and they did not answer the phone for 8 hrs. There was no next flight out, I have missed my wedding because of this.

Liked the crew. Multiple delays. Altered my complete day and plans

Apart from the man snoring very loudly across the aisle from us for about 3.5 of the 5 hour flight it was a great flight. I couldn't get the internet to work and stay working. Texting was intermittent for me.

The plane boarded late and arrived late which wasn't really ideal.

The pretzels have no taste. How about a choice of snacks? The flight itself was fine.

This was my first time using Alaska. The best thing about Alaska is the people. Everyone that I had any contact with couldn’t have been better. So far on this trip no complaints. I will use Alaska again

Full, attentive service from the fist class cabin flight attendant was superb. Really exceeded expectations.

The stewards were too loud and chatty with each other

The flight was CANCELED!!! Can’t get much more “poor” than that. I had to switch to American Airlines, add another layover and got home in Honolulu 4 hours later than I was supposed to be home. One bright spot was Josh with Alaska Airlines at SFO. He got me on a United Flight that got me home a few hours before I would have. Without him I would have gotten home almost 7 hours after my originally scheduled flight.

Canceled my flight within 24 hours, causing me arriving home midnight. Will never book Hawaiian airlines anymore

I like Hawaiian, it was great that they had good internet connection across the Pacific Ocean, thanks to Star Link satellites. The seating was comfortable, ( I was in economy ). Maybe I missed it, but I only got offered a beverage once. It was a nonstop flight KOA to SMF. I would take it again next time I go that way.

I always love flying Hawaii and I have nothing to add

Previously flown Hawaiian Airlines on similar routes, I found Alaska Airlines to be noticeably more comfortable. The seats on Alaska Airlines provided better support and cushioning, which made a significant difference on the long flight to the islands. When you’re spending 5-6 hours in the air, seat comfort really matters, and Alaska Airlines delivered where it counts. After comparing both carriers, I’ve decided to book with Alaska Airlines for all my future Hawaii trips. The superior seat comfort alone makes it worth choosing Alaska over Hawaiian Airlines. If you’re planning a trip to Hawaii and prioritizing comfort, I’d recommend giving Alaska Airlines a try. You won’t be disappointed. Highly recommended for Hawaii travel!

The crew was EXTREMELY helpful And sweet and the flight was smooth!

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.

The entire crew had everything handled and truly worked together. More than once, I saw them hustle down the aisle and back just to serve customers.

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!

Amazing all female crew, including the pilot. Great flight attendants and smooth trip. Food was good. Boarding the plane from back to front would have made things significantly smoother. Took forever to wait for people to clear the alley. A little extra leg room would be nice also. Please thank your flight crew!
