More like CO OnePass
Plus card. There were other versions of CO cards which are more like the old UA Select. Only the Plus card is deemed equivalent to the Explorer card.
I remember reading some official words from Chase that the ineligibility cut off is July 2011 - that is, if your CO card is obtained after July 2011, you would be ineligible for the bonus on the UA Explorer card. There are a few posts about people still have their CO OnePass Plus cards open (converted to UA) and still able to get bonuses on the Explorer cards.
