WHITEamex,
wrong, sadly.
Limits as recently as 3/19 are like this:
Corporate cards (green, gold, plat, and centurion, purple, orange) - $ 0, yes, that's ZERO per month.
OPTIMA-type cards, whether co-branded or not (ie Delta, Starwood, etc) - $1000/mo
As far as I can tell, now you cannot even get a manual pre-authorization to exceed this $1000/mo.
My wife spends more than this at walmart a month. Well, almost as much. Its a farce and a token IMO. just so they can claim affiliation with paypal (and it *is* an AMEX issue, not a paypal issue).
A real slap in the face to corporate cardholders.
