Where the B6 code comes from
B6 is JetBlue's alphanumeric code, assigned at the airline's 2000 launch when the sensible letter pairs for a J or B name were long gone. The B is for Blue, the 6 is just a free digit. JetBlue built its identity on New York JFK and Boston rather than on the code itself.
