In my case, the links didn't appear until my accounts had been open for
3 or 4 months. Usually if there is anything displayed in that corner
it will be an ad for a loan of some sort. The first time the links
appeared I didn't request an increase and they disappeared for
several days (at least). When they came back I applied for an
increase and it was approved. It was a hard pull, so I'm not sure that
it would have been any different if I would have gone through the
credit limit increase request found in the other services tab. In other
words, I'm not certain that having the link present is a sign of
impending luv.
