Boarding was smooth and fast. The travel time was a bit faster than predicted too.

With lack of reclining seats and no complimentary snacks or drinks at all, the comfort scale is lacking. Even the tray tables were replaced by miniature, undersized, pieces. Even with the discounted prices, it’s hard to want to fly with them again.

It was clean, and the crew did great!

Way off schedule, way to tight of space, no way to sleep being such a late flight! As far as a beverage, they were out of everything!! Nice air line for quick trips,but to fly for 4 hrs at night from leaving at 12;00am, just impossible to sleep or really relax.

Premium economy is the way to go for a long haul flight. We were comfortable and able to get some sleep.

The crew on the way to Sydney was a little more present. There was always someone milling in the galley between the business class and premium economy cabin. The crew returning came through the cabin often and were attentive if you asked for them but you had to seek them out.

The crew was lovely. Really nice, and did a wonderful job with the cart service.

We ended up being deleyed about 30 minutes, in damp weather. It's not like it was snowing. Not sure why it took so long. B/c of baggage charges now everyone brings a carry on. This seems to slow the process of boarding as know passengers are asked multiple times to check baggage (for free, which is the one nice thing) before boarding b/c the overheads will be too full. Group 6 which I was in seemed like it was just the rest of the plane. Super busy, took me forever to get to my seat all the way in the back. Why don't airlines reverse board? People sitting in the back should board first. I feel like this would save so much time.

I liked having the built in screen on the a321. Americans streaming service has lots to offer but the built in screens have more choices. I get why they want to just offer the streaming but I appreciate all the choices! There was a group number enforcer at the gate to make boarding more organized! She was polite but told the mobs that try to use the premium line to wait their turn.

I asked for upgrades to and from Chicago. I’m a gold member and fly for leisure fairly often. There are so many people looking for an upgrade these days that you’re rarely getting the opportunity

Everything worked the way it was supposed to. Bag transfer through customs and transfer to domestic was easy.

Snacks and food in general on US operated airlines is generally sad. American Airlines should learn from Qantas about food quality and service.

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.
