My understanding with Cap One is that they will only allow you to have two cards in a given category -- so if you have two "subprime" Cap One cards (I think we figured out that this included secured, platinum, journey, QS1 as well as the cobranded ones) or two "prime" Cap One cards (QS, Venture), you can't get another one. This MAY HAVE changed but I'm pretty sure that's how they operate. It's been a while now but this is probably the explanation here.
As for a PC or CLI, those are definitely YMMV situations. Some people have no problem getting them to waive the annual fee and PC into a more prime card (like QS1 to QS or Platinum to QS) and others can't get them to budge ever. Some people get CLIs out the wazoo and other people are stuck with their opening credit line (or just go through credit steps and then it stalls). Everyone's experience is completely different when it comes to this sort of thing, unfortunately. It all just depends on the profile and what the computer algorithms spit out, heh.
