Perhaps this is just another of the many reasons why AA J service is so hit or (mostly) miss.

IMHO-Lack of training/standard practices in F and J is another indictment of AA "vision", or lack thereof. YMMV

SIDEBAR-I flew JL J NRT-DFW 2 weeks ago. Service impeccable. Food the best! My steak was worthy of a Dallas steakhouse. Turns out the FA who was the "chef" was sent to school to learn how to cook on the plane! Wow!
