All flights operated by AA to JFK, LAX and I believe some DFW flights have the new AA Business class. Unlike the cramped BA CW offering, AA offer a 1-2-1 layout and the product is very similar to that offered by CX and AF. I flew out to LAX on BA and back on AA. The BA seats are smaller, older and the food offering was better on AA too. Where possible I would always fly the new AA business class over BA. With direct aisle access for everyone, it wins hands down. The lounge offerings with AA may not be up to the BA product, but on board with AA is a winner!
