The passenger who say next to me was beligerently intoxicated. Throughout the flight he constantly leaned on me, put his hands on me, and slept on me. I had a horrible flight. The flight crew should have identified this guy and not let him on. It was a good thing I was a male and able to push this guy off me.

Alaska tried to keep us informed after technical issues forced a three-hour delay in the flight. This included communication, snacks, and compensation. Given the circumstances, the ground crew performed well. The cabin crew did a great job.

The technical issues, which caused a number of follow-on issues (over-fueling the plane), was preventable. But ultimately, they solved the problem and got us safely to Spokane.

I enjoyed my flight. Food, entertainment were not applicable for this flight. Having option N/A to respond would get more accurate opinion.

There is nothing I can make negative comment on.

The check in process was cumbersome with being able to partially get checked in at a computer kiosk and then having to wait in line to see an agent while other people are jumping the queue and not having to wait... then having stood in line for 10 minutes an agent tells you that you could have been in the "fast" lane... but there is no or little signage indicating which line you should be in.... that's frustrating. Don't expect your customers to be unconsciously aware of all of your convoluted business practices... put some signs out... we at least like a hint. Other than that, for air travel it was a very good experience.

Entertainment and crew were great- comfortable seats, got to watch a couple of movies with headphones provided by Delta; forgot mine so I assumed I would be miserable thru the whole 4 hour flight. so glad I was wrong! Would definitely take another flight with Delta... looking into the frequent flyer program as we speak

The flight attendant named Steven went so far beyond the call. He was attentive, he fixed our video system when no one else could and when he learned we were celebrating an anniversary he brought us a present. He was awesome!

Staff and crew were very friendly and accommodating. Flight was good and on time.

I had arrived from Ft. McMurray more than 3 hours before my connection, but was was paged for a search just 30 minutes before my flight boarded. Delays in security meeting me almost made me miss my flight. I didn't understand why they waited so long to do the search. It should have been done when I first got there.

Comfortable aircraft. Makes sense to board back of plane first

I was offered water, wine or orange juice but told there wasn't time to offer full beverage options because the flight wasn't long enough. Though the cart was fully stocked. How could it take more time to pour ginger ale than water? Made no sense.

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

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.
