We had a specific situation on our flight tonight that was especially disruptive. Shortly after take-off, my fiancé who was traveling with me, felt the teenager (most likely a minor) directly behind him pushing his seat. My fiancé turned around to ask her to stop. Rather than apologizing and stopping, the teenager immediately began complaining about how my fiancé was encroaching on her space. My fiancé replied that it was well within his rights to lean his seat back. The teenager responded with further complaints. Her comments were out of line and rude. It was clear that she was not satisfied with my fiancé having his seat leaning back. My fiancé eventually put his seat back, and the teenager stopped complaining. We believed that the situation had been resolved, but apparently the teenager was not satisfied. Instead, she went to a flight attendant and lodged a complaint against my fiancé. Rather than hear our side, the flight attendant immediately asked us to move to a different seat. We were forced to move, against our will, to two separate middle seats further forward in the plane. We no longer were able to sit next to each other for the remaining five hours of the flight. And this was all because one particular teenager did not want my fiancé to put his seat back, which he is certainly allowed to do. Overall, the situation was handled poorly. We paid to sit together on a flight, but due to one other passenger's attitude, we were forced to sit in seats that we did not choose apart from one another. The flight attendant should have at least heard our side of the story and offered us an alternative. Instead, we were forced to accommodate another passenger who was in the wrong. Not to mention, throughout this entire process - which lasted about 30 minutes - I was not able to use the GoGo Inflight Internet Package I had just paid for. That was money wasted. The experience was embarrassing, disruptive, and awkward. We love Alaska Airlines, and we are usually pleased with their customer service. However, tonight, the customer service we received did not meet our needs; instead the flight attendant exacerbated the situation and we left our flight feeling frazzled, angry and disappointed.

Getting to where I needed to go

Stopping the plane to fuel at another airport understandable. But then you ran out of food for purchase on the first flight (I was sitting in the back). Then connecting at LAX was horrible. Everyone had connecting flights. Off the plane onto a bus. then through customs then shuffled outside with no guidance from employees. Finally I found someone to ask bc 15-20 people were around me in the same boat. Where the f do we go we wondered. The employee was insanely rude. I’m attentive and I listen. he was saying pay attention I told you go right blah blah blah. He was literally standing there with his arm out pointing right and never said a word to anyone. So once we figured out to go outside and right we had a stressful ten minute wal hoping we were going the right way. We were! We get to tsa and have to go through screening again. Which is insane bc we just got off a plane. The tsa agent told us this happens everyday with a smerk. On top of her attitude, her and the two other lazy ladies on her line were painfully slow. The other two lines went at least twice as fast(no exaggeration!) made it to gate 66 to find it was changed without notice to 63. Made the flight by two minutes or less sweating from running around!

Flight attendants were nice

First time (and hopefully last) flying Alaskan. Boarding was ok, not the most efficient but it worked. Once aboard a predicted snow storm started (in Seattle so not the first time this has happened) and we had to de-ice. This process was exceptionally long, in fact so long that we had to add fuel for the trip. These two delays conveniently “timed out” the pilots, brilliant! Total delay was over 4 hours, all to be blamed on their ineptitude. Seems like the norm for airlines these days but this was blatant mismanagement.

I really wish the airline could sort out the whole "check at the gate for seating" because I don't think anyone wants to buy a plane ticket just to deal with the uncertainty of if they are going to be able to fly or not.

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,
