The Captain of this flight did an awesome land g in Ketchikan, AK. The runway is short and this was the smoothest touchdown for a landing ever! Thank you whoever the Captain was!!!

The only part I could honestly say was I wish I booked an earlier flight to see Ketchikan from above prior to landing.

I checked in to the flight 24 hours ahead to ensure I got an aisle seat, because I knew I’d probably be going back and forth from the bathroom because I had been feeling ill. When I got to the ticket check to board the flight, my name wasn’t found in the system, and I was turned away to go back to the front desk. So I did, and the person there was seemingly able to get me an aisle seat in the same row, just across from where I originally was. But, when I got to the row, another man was in that spot and showed me his ticket which was the same seat I’d seemingly been re-assigned! The middle seat was empty, and so I sat there for the time being, while we enquired about it. One of the flight attendants said they’d look into it, but just seemed to brush it off and never gave us a response. I was mainly annoyed about being shuffled around, getting reassigned a spot and was clear about wanting an aisle seat, and it never happened even though I chose that seat 24 hours ahead in the first place. I felt there were a few chances to make it right, but it never happened.

Flight attendants seemed completely unwilling to accommodate any requests outside of their "service time".

Mediocre 2.0

Our plane was defective so had to be replaced. This is fine, I certainly am willing to wait for a new plane if it means not blowing up over the ocean. The problem was how little the attendants at the gate communicated the situation to us. What should have been a brief layover became a 12 hour nightmare. The gate attendants did finally issue meal vouchers but they waited until 10 minutes before all the restaurants closed and only issued $10 a person. This is enough to buy a hot dog at an airport... We were told there wouldn't be any rescheduling of missed connections until we were "airborne". This resulted in mass panic and confusion upon reaching our destination. We were told to go to the service desk, half an airport away, but once the entire passenger contents of the plane arrived at that far flung service desk, we were mostly turned away to seek help at individual gates. This lack of communication meant I missed the next next available connecting flight and now have a further six hour layover. I understand accidents happen and planes can break down but the nearly complete lack of care and customer attention is, frankly, disappointing. I've now had nearly an entire day added to my travel time. If I'd been willing to loose that time I would have paid $600 less for my ticket. United finally offered a token of their appreciation : a $100 e-voucher. I have spent more than that on food and coffee in airports for the past two days while trying to survive until my next connections.

Fortunately as a passenger the economy flight area was very spacious due to low numbers of passengers. Which provided a comfortable seating space.

The entertainment could and been a little more variable in the film range provided. But generally overall I had a excellent flight. Food was good. Crew were very good and I would definitely consider flying United on my next visit out and recommend that my family did. Thank you United.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
