Other than delays by two-three hours it was good.

The Drop Bag sounded like a good idea, but in reality it was a very long line with few employees to assist as you did the work to check in your bag. Take a carry on bag and skip Drop Bag! Our flight was delayed several times with no explanation. What food? We had a choice of apple juice or water.

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.

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

Leslie the gate agent was incredibly helpful with helping me get on an earlier flight! I saved several hours of airport time thanks to her, and she made the process easy and quick.

Two of the flight attendants were cranky and seemed like they didn’t want to be there. Not up to normal Delta standards. And our bags didn’t make flight to Italy from Amsterdam resulting in having to make a trip back to airport which cost me 75 euros.

The trip to Harrisburg from Detroit was extremely uncomfortable because of heat

Flights were on time, my connecting gate was VERY close to my arrival gate, everything went smooth and made for a delightful experience.

The flight was delayed to board, then delay in landing and extremely bumpy landing.

Late flight, screens not working and still had to pay for a drink

great! appreciated the last minute upgrade to Comfort+ exit row, as well

Crew completed ignored our aisle when giving snacks and coffee

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.

Please stop those idiotic and unrelenting announcements, commercials and stupid credit card drivel. All together about 15 minutes of stupidness that annoys each passenger.

On time. Accommodated carry on and personal bag in the plane. Good entertainment available and access without using own device. Gave a whole can of juice rather than a pour. Seat did not recline much.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.

I like the first class seat amenities like the phone charger on the armrest even though it didnt really work on mine and the partition between the seats. I also liked that there were additional places to stash things during the flight. The food I got was steak and it was really tough to cut with the knife. Chewy too. A little disappointed in that. I liked that your name is on the screen too. nice touch. great service overall.

Good, our flight was delayed but that was totally out of their control due to weather and a presidential visit.

When we boarded we were treated with care and it never stopped. Got towels before breakfast and after snacks was a lovely touch!

Price was crazy watch it if you Chan he your flight

The price. Omg $1100. Was crazy and it was not clear on the website.

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!

The employees at Sioux Falls airport were friendly and helpful. As a veteran/retired military Allegiant allows two checked bags, one carry on bag and a seat on the plane all at no cost. The flight crew and pilots were friendly and very competent.

The check-in and flight crew employees are excellent. The flight was good and the seats were adequate.

The flights to and from Cincinnati were great at being on time for both, departures and arrivals. The planes could use some updating.

It was a dismal experience. The flight was delayed for 4 hours, and we spent hours in the plane, without air, during the summer. We were not provided with water, and the medical assistance was inadequate when it arose.

The landing the pilot was very smooth. The flight attendant was kind of rude.The boarding the plane in punta Gorda was not great made us wait out in the heat 😞

My exit seat was very comfortable Coffee was to be purchased but sodas free 😏

It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

The price was the only good thing about this flight. It was scary during takeoff when the plane tilted side to side. It made me feel very nervous as I have never had a take-off that unsmooth. There was no on-flight movie or music options and the only complimentary option was water. Other airlines offer trail mix or a caramel cookie and pop options as complimentary. This flight was a 2.5 hour flight. I understand for shorter flights not having options, but a flight 2 hours or longer should offer more complimentary options and in flight entertainment. Also the seats did not recline and for a longer flight reclining seats are a must for comfort.

They boarded passengers that sat in the back of the plane first, making boarding very efficient.
