Is this what you mean?

# make sure mod_rewrite is on
RewriteEngine On

# check request URI for AAA and rewrite to /AAA/ (only once)
RewriteCond %{REQUEST_URI} !^/AAA.*
RewriteRule (.*)           /AAA/$1   [L]

# otherwise rewrite to /BBB/
RewriteRule (.*)           /BBB/$1

Also, you might want to try:

RewriteCond %{REQUEST_URI} ^[^A]+AAA.*

instead of the first line, as I can't remember if they're a / at the front of RewriteRules or not...
