So one can choose between: (1) easy to remember or (2) help flyertalkers with referral bonuses.
No, I knew that they work multiple times, too. My point from the start is that the code DELTATRYGOGO will work for anyone with multiple personality disorder unlimited times. Bringing along a unique code that cannot be easily memorized provides no advantage over this, so why do it? (Exception would be to obtain codes for Jan use, which I didn't realize at first. Doesn't help anyone from now through the end of the year, however.)
