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

I think Alaska should start including free meals on these longer trips.

Departed on time and had an efficient boarding process. The inflight wifi was not working on one of the flights.

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.

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.

Again Alaskan and Hawaiian need to consolidate check-in, allow seat reservations on both flights. I wound up in last row because I couldn’t reserve better seat.

The flight was fine, but the Kayak app is terrible. I could not input my flight. I couldn’t use it for anything and it would not even let me try to add a seat once you purchased the ticket you might as well. Delete the Kayak app as far as I’m concerned. I’m done with kayak. Com

The crew was the best I’ve ever had HOWEVER when we arrived in Salt Lake City there were no Alaskan Airline employees to be found so we weren’t able to leave the plane until ANOTHER airline took pity on us. How could that possible happen?

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.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

The flight was flying with 30% capacity. The flight my seat from preferred seating to back of the seat. Even though i can understand that this was to balance the flight weight. The flight attendance decided to do the serving near my seat and in the middle , their noices woke me up from sleep , when i realized that the service has ended and when they were going back asked for a coffee, for which they answered they have completed teh service in my location. That really upset me as they woke me up and also rejected the coffee i asked. I ended up landing with a headache, thanks to the crew that screwed up my travel

Delayed. Hot. Passenger next to me was so large I couldn’t move.

Flight was warm for first few hours and quite rough

First flight out and was 85 minutes delayed. Notification came out way too late

Was forced to check in my small carry on, even though I informed the crew it has very fragile items inside

First class and monitors weren’t working for mine & my husbands. Eventually fixed, but quite annoyed as we bought first class. Also, No foot rests.

It was okay, the food was good, but after the landing there was not enough time for luggage and security to catch a connection. It was crowded on board.

When I went to check in at the United counter in Barcelona, Spain I had 2 different menat 2 different times in United uniforms (standing around with a couple other employees) ask me if I was traveling alone. The one man asked me 3 different ways if I was traveling alone. I am, 68 yeaers old and have all my faculties. I thought it was weird and it made me feel very uncomfortable. What difference does it make if I was traveling alone or with someone? What if I was a recent widow? That would have been horrible. They never gave me a reason why they needed to know who I was traveling with. I was hesitant to question them because I needed to be on that flight.

Crew was great. 2 1/2 hour delay was due to staff needing "rest" was avoidable and self inflicted as United not willing to hire enough crew to keep flight on time.. Ridiculous. The crew and the passengers both suffered due to this.

Fine not above and beyond as I had a connection that was delayed due to maintenance

Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).

Great other than a couple very drunk guys that for a while kept bumping my seat from behind. The staff did their best to control them. Even refused serving them alcohol and allowed the gal sitting next to them to move.

Good crew. Boarding delays. Almost two hours wait for the bags in DC.

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

The seats were comfortable and we had leg room. Great entertainment.
