Landed on time. AA is mostly on or before schedule. Definitely like that part. Smooth flying as well.

No interactions with the crew this time. Boarding is okay.

I miss friendly Southwest. Even the assigned seat is kit enough for me to use AA again. People smile at Southwest and seem to enjoy their job.

All the different prices for seats. I think it is a stupid system. Miss the good old days of air travel.

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!

This flight was delayed for me by 30min, there was a lot of turbulence and didn't serve anything for the flight. Other than that, I was flying with Southwest to different cities all week and everything went well.

I didn't eat or watch movies, so couldn't rate those. The crew we're pleasant and helpful, and the pilot got us there in one piece, which is the important thing. Then, I managed to leave my suitcase behind, after picking it up at baggage claim. I had just arrived at my destination and realized it was missing, and before panic set in I got a call from someone at Alaska Airlines, saying they had my bag. Excellent! I'd definitely fly Alaska again, and recommend it to others. Eileen

Flight was good but my first flight was cancelled which gave me a 6 hour layover in Seattle.

6 hr delay and arrive at Newark at 7:30 am and have to fight traffic to get home

Comfort and quality of the airline is top notch, like its sister company Virgin.

A little hard to get onto the WiFi, but once on, it was fine. Hey ... it’s free so overall, still great

I had a window priority seating, and without notifying me they change my seat to a middle seat and when I called to change it was pretty much told, no other seats available... Too bad.

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.
