These are ones that I'm familiar with too. A lot of 3-letter identifiers
make 'some' sense but I haven't figured out how Carroll, IA got CIN (C
for
Carroll, I for Iowa and N for Neu?), MFE (McAllen Miller International)
and
also JYG... The identifiers with numbers make even less sense...


Can you think of more logical combinations that fit the criteria and are
not
in use?

How about CRL, MCA and SJM for these?
