A lot of people don't count it as part of their overall limits even though it's essentially a revolving credit line, and at a better rate than some of my other cards. A rep even told me it was considered a revolving line internally, the only difference being that your single purchase limit can vary depending on usage, etc etc.

Having a $35k POT doesn't necessarily mean they would let you charge up that much. I have a $35k POT on my PRG, but I'm fairly certain they would cut me off to new charges well before I ever got close.

Might be easier than charging to Amex, then immediately BT to Discover.
It varies by person. If it's very short-term, I agree that paying the interest for a few months can be better financially than paying a 3% transfer fee. (Although Discover does offer 0% fee transfers with 4.99% APR typically, so that throws out that logic.) Amex does offer targeted promotional APRs on POT in the single-digits from time to time.

That link should bring you to this screen which lisyts your APR (painful to see how that's gone up with prime rate changes):

Didn't know it varied by person on charge cards? I thought it was 19.99 or whatever since prime has raised for all... I know plan it changed for different people on revovlers, but not POT rates.. You have a pretty good rate there it appears as mine is 19.99 and I usually get pretty killer apr's on Amex cards being the lowest usually and below their published lowest by asking on my ED card..Always nice having the option in case one goes a bit overboard on a charge card lol
Mine were 15.24% until the prime rate started going up in December 2015. 
Yes, they have a range and most people around here have reported rates significantly higher than mine, so FWIW I feel special. My APRs are all over the board with other lenders (high credit lines with high APRs and lower credit lines with lowest APRs run amok in my profile), but Amex has always treated me well (even if they did drag their feet moving my SPG limit up).
