Well, that link that amgray19 posted includes all kinds of logos, pictures and even Pantone color palletes. Various other things, such as "Mileage Plan," "Partnerships," and even "MVP" and "MVP Gold" use the same font as the logo.

"Script" (different than the logo; example is at the link amgray provided) is used a lot less--usually (as far as I've seen) as, say, subject headers in newsletters, etc., but not in regular usage. The site he linked to mentions something about Cochin, but I didn't see an example of that. Most standard text appears to be Helvetica.
