Seats very comfortable and legroom appreciated. All in all, it was a great experience.

Original flight was canceled, and the automatically booked second flight was immediately delayed. I arrived about 4 hours later than planned with only a $12 meal voucher that didn't fully cover a sandwich at airport prices.

fine. only problem,,,, for some,,,,was that many people started trying to exit from the back of the plane,, . lots of irate people. there should be a flight attendant mid plane..to be sure that doesn't happen. The crew up front had no idea what was happening. One big guy started it..then a bunch of others followed his lead. could have gotten ugly... One man stepped in and questioned those rule breakers.. nothing bad happened,,,but......

Wonderful staff who honored sleepy overnight travelers and still met needs quietly and quickly!

Wonderful respectful staff for a short flight late at night...lots of considerations all met!

I was expecting better service from Alaska Airlines. I registered for assistance since I have a disability. The terminal in Seattle, WA was very unprofessional and at times rude. The BWI location was the exact opposite. I will NOT consider Alaska Airlines for future flights.

Flight was delayed which led to missed connection, but rebooked on a more direct flight at the last minute and arrived in Juneau on time with all our luggage. Little stressful and our family seating got split, but it all worked out in the end.

It was very good and comfortable, Crew was also great

The flight was delayed almost an hour. No wifi on flight.

It was fine. 2 hour delay due to mechanical issue. I understand issues will occur, just wish instead of Capt repeatedly telling us we will be getting off the ground “momentarily” they would just be honest and either say they have no idea-or it’s going to be a few hours! All in all FAs are usually pretty nice :)

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

The first flight was better in terms of the aircraft.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

There's just no way to sit fully upright and comfortably in these seats. There needs to be 2 more inches of room, and that's not something that only one person on the flight needs - the whole flight needs 2 more inches of room. If that means you sell 6 less seats, so be it. It's too close for anyone. Forcing people to pay for "premium" economy just to get "barely enough space to breathe" isn't really an answer to that.

The crew were very nice. The Chocolate is good and v there’s no entertainment. Thanks

The crew were very nice. I would have appreciated a pillow for comfort. I had a special meal that was sloppy, but the salad was great. Thanks

The plane was in Moline all night. Consequently, we assumed an on time departure at 8:15am. Unfortunately, and as is the normal case with United in Moline, we departed 2.5 hours late. When the crew came, it was discovered that there was very little heat in the plane. Seems this should have been checked hours before the crew arrived. Then when we boarded and the plane was to be de-iced, the United de-icing truck was not working! We awaited the American Airlines truck. All of this caused us to miss our connection in Chicago. My suggestion is never take United Airlines flight from Moline. We have been disappointed 80% of the time and have vowed to not take United again from Moline.
