The first few rows of coach are reserved for Elite 1 and Plats...this is a nice benefit on the rare instances where an upgrade doesn't clear, or when I traveling w/ someone who isn't an Elite, and we choose not to upgrade. Getting the bulkhead row (7) on the MD80s is especially nice, as there is a ton of legroom.
Early boarding and FC check-in are also nice perks to have, as is the 1000 "actual" mile minimum.
