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.

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.

I have to rate British Airways as a 10 out of 10 in almost all categories...comfort of the plane, food and service, boarding, notifications, crew, etc. In particular, the long haul flight from London to Seattle everything was truly top notch!

Their baggage handlers damaged several parts on my checked-in luggage...three zipper pulls and one clasp. What are they doing with the bags? How can they damage so many things in one fell swoop? This is a good quality Atlantic suitcase. Also, on the short flights, in this case Madrid to London, they are now charging for EVERYTHING...even water and coffee.

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

The low fare was the best part of the flight, but I later found that it came at a cost!!!!

First of all the Crew was rude and their lack of patience was obvious, the flight was delayed and was no fault of any of the passengers yet we were made to feel as if it was our ( passengers) fault. Secondly, the air was turned down, I guess to conserve fuel, and the plane was unbearably hot, And at no time was food offered for purchase or even a beverage service. I have flow AA for 20+ years and this was the FURST flight I have ever experienced. Sadly I believe it will be my last!!!!

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.

Safe landing

Was charged 65 pounds for checking one bag. This was a big news to me. BA claims it was because I booked through Kayak. Would not have booked the flight. Luggage cost is almost superior to flight cost. Forced me to check my overhead luggage. Flight was delayed one hour because we had to go back to gate to rebLANCE WEIGHT

nice employees

for the second time on this flight, the onboard devise for credit cards would not accept mine. this is the same card i used to book the flight. i complained to british air last time but they obviously haven't fixed the problem. there seems to be a problem using american credit cards these flights. is is a problem because nothing is free. luck;y a flight attendant did feel bad about it and gave me a glass of water

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.
