Excellent Crew - I flew standby, so have great gate agents and flight attendants makes all the difference when you’re hoping for a seat. In flight they are professional and personable and keep you up to date on what you need to know! Plus, I’m always happy when my flights have USB ports so I’m fully charged when I deplane.

I always want more leg room or a little more room under the seat in front of me. But I didn’t upgrade for a roomier seat and there was more than enough overhead space, so truly can’t complain about it!

Flight attendants very attentive and helpful as well as a smooth fligh.

Departed late was the only thing, otherwise very good.

I think better than other airlines. Provided a snack, beverages and wine for purchase. Very friendly team. I had no problems. I really appreciate the late flight from PDX to PHX on weekdays. It is very convenient for work related travel. I don't think any other airline flight back to PHX that late. I also appreciate that they offer power, free limited WIFI (to text/send messages).

I did not really dislike anything. I think it was a good experience overall. However, there is room for improvement for all airlines. It would be nice to see more comfortable seats, additional amenities and lower prices. I bought the last minute ticket one war PDX to PHX for $500. I think that was a little expensive, even for last minute traveling.

Excellent 8.0

No crying babies and outlets at all seats.

I wish the seats reclined more or had more padding.

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.
