As always the crew were super polite and friendly, sadly the weather & a minor mechanical issue reduced the quality of the flight, all’s well as it turned out. Still my favorite airline to fly with

Best flights I e been on. Need gluten free snacks

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.

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$

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

No beverage/snack service without any explanation or reason. Late boarding and delayed flight.

more room in seats, larger snacks, more comms with delays

There was overbooking that delayed boarding. Then an airport emergency lockdown that caused further delays in boarding. However the time was made up during flight and there was a minimal delay in landing. Everything else was excellent.

Delta is the best. It was all very easy and on time.

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

Wifi worked inconsistently; outlet to charge computer did not work.

Gate agent in LAS named Juliett should win an award for excellent customer service.

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.

typical but they have finally enhanced the wifi on some UA flights. Boy, its such a huge improvement

This was a small aircraft (relatively) and we were delayed half an hour on takeoff, which is not the airlines fault.

Return flight was perfect. All on time and no hiccups. However, going was another story. I don't blame United for the weather, but I am rather disappointed in its response to my getting stranded in my layover city for the night. United gave me a $20 food voucher. That's it. But besides this policy, the employees were incredibly helpful rerouting me to my final destination in Fort Lauderdale, FL. So overall, 8 out of 10. 10 out of 10 for flight comfort, inflight service and before flight service. 5 out of 10 for layover handling.

Quinoa chocolate cookies are my favorite! Would be nice to have internet service like American

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.

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.
