I finally got to Portland.

The plane did not arrive at gate, they gave us poor/invalid excuses as to why there was no plane. We moved from gate 73A to gate 82, in another terminal back to gate 73A for no explainable reason. Finally we left after having to checked in now at gate 73.....what a mess and over 2hrs late!

There was plenty of room because I upgraded to 1st class. The crew was friendly.

My tv didn't work for the first 20 mins of the flight and had to be reset. They only had one of the drinks I wanted. I would have thought being that it was around lunchtime they would have served more than a bag of chips or banana. In coach, you get a bag of pretzels and/ or a cookie sometimes. American Airlines provides warm nuts and a fresh baked cookie and I had to pay more for the upgrade than I did on American for a longer flight.

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.
