We arrived on time.

These planes feel like they are made of Legos. They are absurdly tiny and uncomfortable (and I am a small woman). Hot and stinky when boarding and no room for you or your carry on luggage. The days of glamorous air travel seem very far away.

It was a short flight to begin with but due to winds it was delayed.

Due to bumpy air nothing but water was handed out to cabin passengers. 1st class managed tho. We were asked to stay seated almost the entire flight, although people still went to restroom as needed. After a late night it would have been nice for a little bite to eat. But apparently mother nature thought otherwise.

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.

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.
