Alaska Airlines has a great fruit and cheese plate for $7.50. GOGO app gives a good selection of movies, tv shows and HGTV!

Attendant was much more pleasant to the two men around me. Such a full flight, we were told to sit down until the food cart was done to access the lavatory. Too narrow of an aisle!

Love the fact Alaskan has a few more inches of leg room. The plane was actually at a good temperature rather than the normal freezing!

Boarding and disembarking is SO slow at pretty much all airlines. It would be great if SOMEONE would come up with a better plan.

I took American's first direct flight between Philadelphia and San Antonio. It was a nice plane, good service, and amenities for a cost. Love that the plane had plugs!

Direct flight from desired origin to destination Boarding by zones

Uncomfortable, small, seat space with inadequate legroom. Lack of personal entertainment options. Paid extra for earlier boarding group which only benefited me by about 5 people. (NOT WORTH IT!) Lack of complimentary food options. (Pay for everything)

Three hours delay. I paid for a upgrade to first class. But because of the flight change i didn't get to keep my upgrade and I had to beg for a refund. I have had two trips in the past 5 days and all flights have been anywhere from 1 to 3 hours late. Worst experience with AA I have had in a long time.

The staff were fine, nothing really great, but nothing bad either.

So, we'll start with boarding. Why airlines can't figure out to board the plane from back to front is beyond me. No, let's load front to back so everyone has to uncomfortably shove past the people who have already taken their seats at the front of the plane. Then you get back there and all the overhead bins are full because everyone takes as many bags as possible onto the plane. Then you have to sacrifice the already tiny amount of foot room, "to put the bag fully underneath the seat in front of you." At this point you should be fine, except if you're over five and a half feet tall (I don't know if that's true I'm 6'2" and 275 lbs,) because then your knees are going to be buried so deep in the chair in front of you that the person up there doesn't even need a seat they can just sit on your knees. Luckily for you tall people, they put a nice metal rod just about knee level to really dig in and cause pain . . . Yay! Being a big guy, you try to be considerate and fold your arms in to give the person next to you as much space as possible, but don't expect that back as they'll spread out and become as wide as possible. Then to distract yourself from the discomfort, you try to use the free in flight entertainment via the United app, but "it's not available right now." In summation either be short and small or be rich and buy the seats with extra legroom when you fly United.

The crew was friendly and informative. They were very helpful. The

The seats were uncomfortable. They were hard and so narrow I had to sit crooked in the seat to keep from getting banged into by the service carts and every person going by to the bathrooms. I'm not tiny, but I'm not huge either, it was just overcrowded. It was also very hot in the airplane the entire way from Phoenix to Spokane. My husband, who is always cold, was even hot.

The check-in staff were very friendly and helpful.

I already knew I was going to pay $200 to ship my boards back home (I wonder if golf clubs which are roughly the same size cost as much,) but when pre-purchasing through the app for an "oversized" bag you have to put a "one" in the checked bag and a "one" in the oversized bag even though they're the same bag, but then they charge you for two, and when you tell the check-in person that you only have one bag of course they can't issue a refund. No, they tell you that you get to call customer service when you return home.

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.
