We were walking towards our seats near the end of the aircraft when this flight attendant stopped us from loading our hand luggage in the overhead bins. She made us stuff them under the seats in front of us. There was space im the overhead bin, but there was a bunch of stuff that belonged to the cabin crew. Rude.

Poor Service. The service of drinks is done very poorly. Really concerned with the attitude. Never need those complimentary drinks.

I did like that "new plane" smell. Good pretzels.

Plane was too new; computer system hadn't been set right. Left 45 minutes late, though made up some lost time in the air. Very rude passengers (obviously not the airline's fault, I know). Everyone thinks they should be the first to get off the plane!

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 a fair amount of leg room.

Boarding could be a little frustrating because groups 3 4 5 were 1 lane and there wasn't a lot of room in the airport. Also, there wasn't a lot of time to get from one side of the airport to the other to stop at the restroom and get a real meal, since there was nothing served on the previous flight. Due to turbulence there was nothing served on the flight, which is beyond the control of the crew. They knrw ahead of time about the turbulence, perhaps they could have quickly passed out pretzels or cookie before the flight took off.

The pilot seemed good and the staff on the plane were nice overall

Customer service from the group staff that checked us in was horrendous... (Lisa from Chicago ). We were not aware one of us needed eTA to fly through Canada and the agent was so belittling, rude and plane wrong with her information, that if it had not for our smarts, we might have not made it to our destination. I do not spend so much money to fly with an airline, whose agents treat it me like this! She really should be fired for her terrible manners and for giving customers wrong information..the second supervisor we talked to helped us, but the impression we got from the agent was so terrible, that it was hard to feel any good...no food on a flight during lunch hour, seems unfitting.

The seats are large, but they tilt forward. I'm 6'2" and have anxiety issues related to spinal problems. That forward pitch in the seat (half way up the seat) is an painful problem for people like me.

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,
