The flight was direct, anytime a flight is on time, and there's not a layover that risk yet another delay is a win!!

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

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

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.

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

Larger seats with a bit more room would be good! Thanks for all your hard work. I think we are all feeling a bit down these days economically and your positive attitudes, both from SJC to Seattle and from Seattle to Bozeman makes more of a difference than you can see! Thank you and Merry Christmas! I hope all your financial needs are met and that very good things come your way.

I purchased a 1st class ticket and unfortunately the main flight attendant was not the best and seemed more interested in her phone than the passengers at times. Then the plane didn’t get restocked and the only snacks for this flight were pretzels. However I would like to say that the rest of the flight crew and ground crew at the airport we’re great, especially the people that wheeled me around the airport some and then the one getting me to the plane and the automated wheelchair that wheeled me through the airport.

Flight was delayed as it always is with Alaska airlines. Particularly to smaller airports. No AC on the plane so it was miserably hot.

I liked that it didn't take 10 hours to drive here. Super short trip!

The ac must have died, it was way to hot on this flight. Boarding g was chaotic. The flight was delayed for boarding. Not a great experience.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

Other airlines were canceling flights but Delta got us home. Crew was friendly and professional. It would have been nice to have had a little more notice about the delays because we had already arrived at the airport when the first of several delays were communicated but I understand that storm forecasting isn’t simple and we were grateful that Delta didn’t just cancel the flight.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

One of the best crews and best flights I’ve ever had! Really great experience

On time departure and early arrival. Kind and professional service from flight crew

The bus ride from the terminal to board the plane is uncomfortable and stressful when making a connection.
