The new process, which was tested at seven major airports this year, "saves overall boarding time by allowing customers who are traveling light to board earlier," the airline said in a statement.
The new procedure will have customers with one personal carry-on item that can fit under a seat given boarding privileges before Group 2, the airline said.
Timeliness is critical for "a more efficient and enjoyable customer journey," AA said, noting on-time performance records are a decisive factor in how passengers rate their air travel experiences.
"American expects to see a notable reduction in average boarding time per flight with the new boarding process," the airline said.
