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.

Getting off of that plane.

I understand delays happen and are sometimes out of your control. However, customer service is something that you can, should, and must control. I witnessed a lack of self control of the American employees (including a Supervisor) and every point of my trip w/your customers. I was embarrassed for the American executive team.

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.

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.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
