Wonderful as always! Pleasant staff, smooth ride, and timely departure.

The agent changed my seat and upgraded me free. The flights are ALWAYS delayed. We sat there almost an hour while the plane was held for 4 passengers. I was then unable to make my connecting flight. This is why I dont fly alaska unless there are no more flights with delta

Flight was scheduled to leave at 6a and delayed for 5 hours due to “mechanical” issues. Everyone else on the flight received an email voucher for $24 of food for the delay, except for our group. Also the carry on luggage bins were full and the crew requested that everyone to pass their carry ons back up to the front while everyone was still standing. They gave no other direction and kept rushing the process. After all bags were sent up, they then asked for seat #s to go with each bag… They should have probably had everyone get to their sits and then pass the bags up in a controlled process.

From Las Vegas to Boise all went well. However, our flight was delayed in Boise and I missed my connecting flight from Seattle to Pasco. Moreover, the last flight to Pasco was full and I was booked on the 11:30 flight Sunday and given a hotel accommodation. However, I was scheduled to deliver the Sunday morning service at my church and needed to arrive no later than 10:00. Therefore, I booked a Delta flight scheduled to arrive in Pasco at 23:09. My piece of luggage checked in Las Vegas arrived in Pasco earlier today. I waited at the airport for over an hour last night to speak with an Alaska agent to no avail. I went back after church this morning in search of my piece of luggage and it could not be located. After waiting for 40 minutes to speak to the agent authorized to take my claim, he announced that he was closing the counter to assist on the flight line but not before providing me with a telephone number that would help me with filing my claim. Before I was able to make the call (due to other factors) I received a call from Alaska agent informing me that my luggage had just arrived and I am now waiting for it to be delivered. I deliberately took the more complicated route home to ensure that I would be home in plenty of time to prepare for myself for the Sunday service and accommodate my relatives’ needs. I believe the airport is undermanned given the number of flights coming in and going out. It was fiasco last night with three flights waiting for luggage and another flight landing within minutes. Today’s problems stemmed from a lack of cross training and a serious amount of cargo/baggage going out and too few people scheduled to cover.

My flight from Spokane to Seattle was delayed about 26 minutes. I arrived at Seattle Airport at 3:21. My flight to Idaho Falls left at 3:35 and you all wouldn't wait for me. I ran for the gate and It would have cost you probably 10 min to wait. Now, I'm stuck at the Seattle airport for 5 hours. I would understand if waiting put you 30 min behind or an hour but I checked into that flight, you knew I was coming, and that my flight was delayed.

Alaska Airlines has the best service of airlines I have flown the last couple years. I always choose them first.

I know there were a lot of delayed flights, mine from Portland to Eugene was delayed by 3 hours, but not from one employee was there a" we are so sorry about the delay or is there anything we could get you, I thought it was very un-professional and rude.

The seats were not very comfortable and there were no TV screens. Boarding was pretty fast because there were so few people on such a small plane and I appreciated that they still gave us our snack and drinks, however I really wish they would come up with a good gluten-free snack.

Flight crew and flight were good. But it departed two hours late.

Pretzels are always a disappointment. Cheezits, Sun Chips, trail mix, anything else would be nice.

Perhaps when you’re sitting in 1st class and the crew closes the bathroom for the pilots, there could be a notification other than holding your hands up as a blockade when you get there and you’re told the restrooms are closed please turn around … especially at night when visibility is poor and you’re met by a flight attendants with their arms up

First class is comfortable. Enjoyed a movie and was able to relax compared to coach.

Loved flying First Class. Very comfortable. The seat was amazing. Enjoyed a movie and was able to relax so much better than in coach.

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The WiFi was not working. That made for a long flight.

Absolutely no communication on why there's a delay and multiple flight time reschedules. I would have canceled the flight and drove back home if I known it was going to be rescheduled 3 or 4 times.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

Stop changing gates. Stop cancelling flights Stop moving my seat.
