I liked the way the AA gate supervisor too charge of the problem and solved it, with great deal of personal imvolvement and follow up. Also check-in crew was very much the best. I would say that AA showed the best of passages care to me. Truly outstanding.

Because of a mixup, though not of AA doing, I was literally forgotten at the gate. However, AA personnel showed the very best of can-do attitude and got me home for Thanksgiving. I am very proud of everyone working at AA at the TPA airport.

seat and seating was nice, boarding was efficient, movies okay

while the dinner was okay, the stromboli which came as a snack of sorts was terrible and caused me to be "on the run" for the next 12 hours. the last five hours of the flight and then at home were awful

When I had to change my wife's ticket due to an emergency, we were charged over $415.00. That is unfair.

Staff were friendly and attentive. Boarding was good - efficient and quick.

Seats were not that comfortable. Aircraft very noisy. Competition offers a much better service. Transfer in Atlanta was a nightmare, taking almost two hours from landing to getting to the domestic gate for the next sector. only three immigration staff working.

The gentleman at the gate was super helpful and helped us check our bags at the gate.

Zero leg room. Zero arm room. The entertainment system did not function. No food for such a long flight unless you pay more then the food is actually worth.

First Class seating was of course better than economy.

Flight to Maui had no Mai Tai drinks available, no heated towels, no dessert, barely any service from the flight attendant(s).

YYC is a nice airport. I have found I like Canadian's more then Americans when it come to air travel.

LAX is not a convenient airport at all.

Everything about the flight was awful. Food pathetic, my monitor didn’t work, smooshed between 2 overweight passengers. Flight crew lacked simple etiquette.

Prices are per person, are for e–tickets and include all taxes & fees in CAD.

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.
