There may be no difference. The other offer may simply be one that was written up before these changes (which are only a couple weeks old). In case you haven't read enough of this thread to know, lots of cards that were obtained in offers that have already gone away are getting these benefits.

Differences in offers do not necessarily relate to differences in cards. Citi contantly puts out many simultaneous different signup offers for the very same cards. In Citi's eyes, these different signup offers are for different audiences (perhaps for ads in different publications or on different websites?), but of course here at FT we tend to find most of them and put them all together for you. (Hint: Most of them are in form of AWAYn or FLYn or TRAVELn or such, followed by citicards.com, where "n" is a single digit. Just trying all those 30ish or 40ish combinations can find you oodles of slightly differnt offers for the same few cards over and over and over again.)
