After running a test of the program in several cities, American Airlines has decided to make is official:

Passengers traveling with just one small carry-on that will fit under the seat in front of them will now be allowed to board earlier than other customers – before Group 2.

The program was tested in Austin, Baltimore, Denver, Fort Lauderdale, Kansas City, Mo.,Minneapolis-St. Paul, and Washington-Dulles and the airline expects this new policy to speed up average boarding times.

No doubt it also expects to hear some whining from customers in Group 2 who will now  have to board a bit later in the process.
