Eva Airlines attendants were wonderful. I really enjoyed the hot meals. They always greeted me with a warm smile. I'm looking forward to flying back to the USA with them again!

Eva Airlines attendants were wonderful. I really enjoyed the hot meals. They always greeted me with a warm smile. I'm looking forward to flying back to the USA with them again!

Didn’t even get on, check my flight to Seattle for details. Do better Alaska.

Flight was cancelled which destroyed the rest of our journey.

WOuld have liked coffee or pretzels but other than that, crew and pilot and flight were great. Seat was great, too.

The overhead storage was already packed full when I boarded (I fly peasant class), but the attendant played some Tetris and made a spot for my small suitcase. Thanks!

The flight 2161 was cancelled after repeated delays; for some reason the crew and not the tower located in Billings, Montana made the call. A cancelled flight is not a big deal, it happens. It was very disappointing that upon cancelling the flight it was a free for all to get to the counter for rebooking. Priority seating and first class ticket holders should have been giving priority to get on the next available flight. Most would agree that the process of moving states away, w/a cat, is stressful. A cancelled flight, 90 minutes to rebook, no place to stay, medication that was to be refrigerated and trying to find a local pet friendly hotel significantly added to the stress. Had I been able to rebook (per priority boarding SOP) I could have called the place I had just checked out of as my room most likely was just as I'd left it, including with pet supplies (which also had to be repurchased). While waiting to rebook, many of us called Alaska Airlines 800 number hoping to get a new flight; the waiting time -- this is not a joke -- was eight (8) hours, which dropped to "just" two (2) hours about 45-minutes later. Due to the cancellation I had to spend $268.75 and I still have not been refunded for the change in ticket (first class to regular). Each time I've call, five times now, the wait time was absurd, or a message of call back is given. Hopefully visiting the airport and talking with an agent face to face will be the final chapter to this experience. Alaska has been my go to air travel for years, hopefully this trip was just a hiccup. A system that forces customer's to spend hours of their time (money) to get a just due refund is not a working system. I suggest Alaska Airlines hire more representatives to handle calls; time is more valuable than money, spending 90 minutes to rebook a flight, without the difference being automatic is absurd. There are things called computers, they do amazing things. Once the flight was cancelled, only three agents were working to rebook the PAX, This too was unacceptable. First class ticket holders pay for first-class service, this should include rebooking on flights that are cancelled. I recall a time when flights were cancelled the airline would offer a hotel should the next flight not be until the following day? I had no idea that was no longer SOP; many could return home, several of us could not. The agents were pleasant once the PAX had their turn to rebook, this was true down in baggage area as well. The flight out the next day was also what I'd come to find of Alaska Airlines.

Snacks for our toddler could have been better, front the standpoint of variety but that’s not any different from other airlines.

The crew inside the airport for Alaska was rude, lazy and incompetent

I fell asleep and missed my flight and they rescheduled me no problem. Staff was professional and the plane was clean. I was very happy with my experience.

I enjoyed the Starlink access but didn't have much time to use it. It also kept dropping me so I gave up. The food was very good though when I asked for a different "dessert" they didn't have anything. Chocolate Brownie Cookies are not suitable for everyone...maybe children. The flight staff were amazing - at least in First Class! My first time ever! The trip from Boise to San Diego was FAR better than going to Boise.

Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Flight attendants were great. Cheerful, upbeat and friendly. Jet, in particular, was fantastic.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

Flight delayed four separate times. I’m now one hour hours late to landing.
