They removed the cover off my checked bag and threw it away.

late flight, no wifi, no entertainment, no snack. What are you coming to????

They changed our flight to Kalispel and we ended up getting there close to midnight. The return flight got changed as well by a few hours. Then of course some issues with the plane and we were even later. First time flying Alaska, may be my last.

Missoula is a great airport. Desk and gate crews were very helpful and friendly

The flight was delayed out of BIL so many times that I was not able to make my connection. I was rebooked for the next day, losing a full day of my trip. I still have not been compensated as promised.

2 hour delay. Then some luggage was unloaded at 1baggage claim #7 then without notice the baggage claim was changed to #12. No one informed the passengers they were changing baggage claim turnstile. Several of us waited for 90 minutes after the 1st turnstile stopped and changed to other flights luggage.

They changed the flight time from 4:00 to 1:50. We missed the flight because we did not know. We were not entitled to any sort of refund.

Flight attendants were great, legroom in main cabin not so good.

Security wasn't helpful for my age, but that wasn't Alaskas fault Baggage clain in Seattle was too time-consuming with changes to the claim carousel.

i had asked a flight staff member For a seltzer from the non-alcoholic drink list and was given a hard cider that costed 9$

wifi too slow or would not connect and entertainment kept on freezing

Cancelled my flight. Left me in airport for 12 hours. Rude gate attendants. Worst delta experience I’ve had. I hope they have a focus group and return to thinking about customer service.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

Pushing back flight and ultimately cancelling it after multiple changes and hours of delays. Comm were terrible as to what was going on and what options were available.

Even though we arrived early and checked in, for some unexplained reason, our bags were removed from the plane and put on the next flight. It took over 12 hours after arriving to get our bags.

Stewardess was not accommodating when I requested a second drink.

Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Didn’t make the flight. My connecting flight was an hour late and I missed the flight. You rerouted me thru Atlanta and I arrived in Rome over 10 hour after my original Rome arrival time. You also left my luggage in Atlanta and it took you three day to get my bag to meI spent 4 days in the same cloths, I had packed my prescriptions in the lost bag and went 3 days withoutMy heart meds.

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.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The amount of seating is ridiculously small. Three points to consider Point One: Your in flight magazine needs to be smaller. Do you realize I can't even hold it in a reading position because of the limited space in front of me? It's a hangover from the past and if you want anyone to read it, it must be smaller. Point two: It is very uncomfortable for a lady to be sitting next to a strange man and constantly rubbing upper arms even when both of our elbows are within the arm rests. And larger men (whom I pity in this confined predicament) also tend to spread their legs into my leg space which requires me to hold my legs into a smaller position. Point three: The seats seem to position one's body in an unusually upright manner and the head rests push the head farther forward. I gave a small effort to see if the headrest could be removed but didn't want to break it or cause a scene with my efforts. I finally put my jacket behind my back to place my body more forward to match the head rest. The service was fine and I noticed ALL staff worked at smiling and greeting passengers. That was nice. No one likes to fly anymore as it is an endurance rather than a pleasure.
