Successful Unionized Companies

In response to Andrew Ross Sorkin's declaration that it's hard to name of successful unionized companies, readers offer the following candidates (we'll be refining this list):

Kroger
Southwest Airlines
All six major Hollywood studios
AT&T (I think all the telecoms qualify as successful and unionized, but we're checking)
Costco (not entirely unionized, but that gets at another issue, which is how many companies have important divisions or subsidiaries which may be heavily unionized, while other elements of their business are not)
CSX (the nation's other major railroads also remain profitable and heavily unionized)
Caterpillar (not exactly union friendly and many labor disputes over the years, but not union-free yet)
Anheuser Busch (pre-merger they were profitable and had significant union presence)
Safeway (.pdf)
Exxon (the profitability of the major oil companies is clear, and they are unionized at least within their refinery operations)
Alaska Air
US Steel (yes, they did make a profit)
IBM
NFL, MLB, NBA, NHL
Boeing
Disney (still profitable in 2008)
GE
Kraft Foods
General Mills
