We arrived on time.

These planes feel like they are made of Legos. They are absurdly tiny and uncomfortable (and I am a small woman). Hot and stinky when boarding and no room for you or your carry on luggage. The days of glamorous air travel seem very far away.

The complementary snacks and drinks were good

Our flight attendant was late which caused us to be late so I had to change my flight and take a taxi go to LAX to catch a different flight and I was up for a total of 25 hours until I arrived at my final destination(my hotel) thanks a lot I will never use American Airline again if I have a choice of other airlines

Had xtra legroom and Wi-Fi

I paid the xtra $99 for the economy plus but my headphone jack didn’t work so I couldn’t watch a movie and my tray table was broken so I had to hold my drink and fumble with my food. The flight attendant tried to fix it but couldn’t. Made my 6 hour flight feel like 12 hours.

No baggage controls from seat 18 to 28 no bags would fit. As we exited all the front rows we're waiting to get there bags stored in back of planes overhead bins. That's just not right, especially when they charge us extra to take a bag for overhead bins storage.

Not a single part has a positive remark

Well - this partner of westjet was terrible. The amount of re direction to get to the final terminal was absurd .. that's just my venting My real problem is that then "crew" or team that represent s the American Airlines / compass part was just useless. A hand full of people - myself included didn't get a chance to board the plane as they didn't make any announcements. Beyond disappointing. When you check in they take your cell phone "in case " well no call no txt no nothing. It was a joke the level of service No apologies or anything just a group of any tired patrons getting the worst customer experience. I'll never EVER book a flight that has anything to do with American Airlines or its partners

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.
