From the
One World Explorer Ticket FAQ's thread (sticky at the top of the page):
ONE or OWE = oneworld Explorer ticket
DONE4 = D class (business class) oneworld Explorer ticket for 4 continents. The initial letter is A, D or L depending on whether it is First, Bus. or Economy, and the final number is the number of continents, 3-6 (sometimes a * is used to indicate a generic question/response, eg. *ONE4 or *ONE*)
