There's no "complimentary" snacks on Frontier. Which is fine, their flights are cheap and comfortable and the snacks are affordable. I also don't really appreciate having to pay for a carry on. I knew about this so made sure my bag would be considered a personal item, but I just don't know how I feel about that as a backpack may not even fit under that seat. But again, the flight was cheap. So, I don't know.

The staff on the flight was awesome, very helpful and kind to my friend who is terrified to fly. We were even ahead of schedule.

To pay for a carry on item is just crazy to me... not to mention you have to pay for beverages and snacks. All you are given is water.

Flight was late and crew was very rude about it. Not to mention the flight times kept incorrectly updating and I almost missed my flight even though I was 4 hours early to the gate. Worst experience flying that I have had.

I was told repeatedly I was in the wrong seat and told to show my boarding pass because I did not appear to the stewardess to belong in first class. No other passenger in first class was treated this way. It was rude and embarrassing, and frankly very unprofessional.

Alaska Airlines has been an excellent airline for many years. Being a Seattle native I have had a chance to use Alaska Airlines many times. All of the staff are friendly, professional and patient. The planes are modern and the flight crews the best.

Last row seats don't recline. Unfortunate while on a red eye flight. There is no entertainment. Flight attendants could learn to juggle or do some magic tricks. Tell jokes maybe?

Hospitality of the crew.

My luggage that was to be loaded in the cargo area of the plane never was put on the plane. No clothes, no shoes, no medications, no gps radio equiptment, and no special fishing equiptment, (as I was on a sportfishing vacation). Really, Really dissappointed.

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.
