Flight was delayed hour and a half. Gate was changed 3 times. After boarding, sat in airplane for another hour while mechanic checked windshield. Total of 2 1/2 hrs behind schedule. Very tiring since I had ben up since 4 am to complete the flight from Honolulu to Milwaukee.

Eva Airlines attendants were wonderful. I really enjoyed the hot meals. They always greeted me with a warm smile. I'm looking forward to flying back to the USA with them again!

The flights left both airports on schedule. The flight from Idaho Falls to Seattle was a typical commuter trip. The flight from Seattle to Maui was not good: It was too long for a flight in a single-aisle plane and too cramped. I kept asking myself if I would ever visit Maui again if airlines continue to run this long flight like a typical short commuter flight. I am not looking forward to the trip home.

Flight was on time. Staff was polite and efficient. The snacks were good - only an hour and a half flight. No entertainment but didn't expect that. We brought our own things to do.

Food was just ok..had snack box :( Crew was very nice

Everything smooth (including the landing) and on time. Easy. Thanks.

The boarding in Idaho Falls was terrific. The plane was a bit sad, and the snax were subpar. Mostly, I was just grossed out by the Alaska gates in Seattle. EW! Smelly and cramped and dingy!

Boarding took longer, to shuttle to plane. Crew/pilot were great.

I was a little hesitant at first because I never flew on Alaska Airlines before. However at the time of me booking; this airline was one of few that were affordable & had a much needed direct flight option. I was more relieved when I got to the airport & saw that my local relatives chose the same flights. Also, on the flight to Seattle I chatted with a gentleman who flies more frequently than I do & gave Alaska Airlines a higher rating over competing airlines.

The Alaska employees in Milwaukee and MKE to SEA were top notch, very nice and polite. Seattle and SEA to MKE, not so much. I spent a lot to upgrade to 1st, and other than a little more seat width, it was a waste of money. Both legs of the flight, the seat bottom cushion sloped forward and I kept sliding out of my seat with every little bump, so I got no rest at all. MKE to SEA, the food was awful. If I had known that I was going to get a bowl of sawdust and dried rotten fruit for a meal. I would have stayed coach and saved a bundle of money. The cabin crew was excellent however. Alaska needs to enforce the rule that the seats at the gate stay open for passengers. I can't blame Alaska for the rude treatment of TSA swine, but they can make sure a hundred people get seats to wait an hour for their flights because a hundred jerks need to take every available seat for their bags and water bottles. The food from SEA to MKE was much better, but the cabin crew was not very pleasant. To top it all off, I found out that the woman seated next to me paid a lot less for the upgrade than I did. After arriving at MKE, everyone waited at least forty five minutes for our bags to arrive in a completely empty airport. So much for the promise of twenty minutes to get bags. In summary, the upgrade to first class wasn't worth the high price on Alaska. When I pay that much, I expect better service and treatment.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

Deplaning was delayed because of Jetbridge equipment issues in MKE, causing an issue on an otherwise great flight.

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

United Airlines was fantastic, however, UnderPricer was a nightmare. I got to the airport 4 hours before my flight. We are moving to New Zealand so had quite a bit of baggage (16 checked items) and so wanted to have plenty of time to get everything taken care of properly. When I went to check in they (United) could only find a ticket for me. The 5 tickets for my children were never officially ticketed. I called Underpricer and they told me it was United's fault and United told me that Underpricer just needs to reissue the tickets, but they refused to. I asked the Underpricer agent to transfer me to his supervisor as I was not getting the help I needed. He told me the supervisor was busy but that he would call me back in 30 minutes. 30 minutes came and went with no phone call. After an hour I called Underpricer back but they would not let me talk to the person I had talked to before, just told me that he was talking with the supervisor and technical support. I called again an hour later, was told the same thing. I tried again later, with only about 30 minutes until my flight was scheduled to leave (meaning I had been at the airport for more than 3 hours with my 5 children trying to get ticketed and board the flight). Also, my husband had moved to New Zealand 3 months prior, I haven't seen him in 3 months, my children hadn't seen their dad in 3 months, we were all extremely eager to get on that flight and get to New Zealand. The situation with the tickets did not get resolved until after it was too late to check our luggage and board our flight. We were devastated. My 11 year old son was in tears at not being able to be on his way to see his dad. Thankfully we were rebooked for the next evening, but that night it felt devastating. We'd been at the airport for 4 hours waiting. My in-laws waited with me and then helped me reload all our baggage and took us home to stay with them for the night. On the newly booked flights we could not sit together - my children were spread throughout the plane. So, even though I had paid extra to select our seats after buying my seats from Underpricer only two of us were able to sit together (thankful that my 11 year old wasn't all by himself, but not happy that my 14 & 16 year old daughters were seated by strangers). I really feel that Underpricer should refund me what I paid for the seating ($120 USD). It was a very frustrating situation and I plan on never using Kayak or Underpricer ever again.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

The wi-fi was awful. I paid $8 each way and got little , except frustration. .
