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.
I have hada VISA with them for over 20 years. it was converted to a Flagship wheneer they started that program.I check my VISA regularly but never see the link. i a msure the rest of you do but I suspect it is only there for some people with the likely criteris being those that are somehow "pre approved."
