same as the first when you pay for choice of seats than you don't receive them its very frustrating it was an extra fee of $80 dollars Craig Molan

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.

No notice of gate change at the original gate. When my mobile boarding pass didn't scan, staff looked up the wrong name in trying to place me.

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

Flight was delayed and we were on the runway after landing for 30 mins

We were delayed so pilots can rest and had no WiFi the whole trip. First class seats are small compared to other planes

The experience was bad. Flight was delayed to handle maintenance (understandable) but still there was some dew forming and dropping as droplets on few seats. Internet at best was allowing some browsing but at a snail pace.

We were delayed 2 hours because of a broken seat. Other than that it was a very nice flight.

There needs to be better accommodations for waiting passengers. A a designated standing space that is separated and away from concourse traffic.

My seats are comfortable because I choose to fly in the exit rows and this time upgraded to first class with minimum sky miles. Otherwise, I would not be happy in regular seats or even middle comfort seats. Onboarding on the return flight from Nashville to Atlanta was hot and very uncomfortable for over 30 minutes due to extreme hot weather. However, Delta should provide some other air flow option as it was almost unbearable until 10 minutes after take-off. First class seats should be equipped with cup holders. Currently, the middle console is used and is flat and prone to spilling drinks.

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

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

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

Flight did not have wifi service. It was experiencing technical difficulties. Definitely and old plane that needs updating.

Very Poor. Significant delays getting to Chicago and then very poor communication on delays in Chicago to Cleveland. We could have rented a car and driven there faster than the delays ended up being.

The app logs you out right when you are boarding requiring all passwords and reservation number for the flight. Super annoying

The pre-order only approach for fresh food is really challenging

the seat has a problem. the back had a hole.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Please please take consideration when setting cabin temperature. The vents were not functional and it was over 70 degrees in the cabin during the winter months when most people are used to much cooler indoor temperatures. I was down to my white t-shirt and the sweat pants I wore from Auckland to San Francisco and was sweating profusely and there was NO VENT!
