Earlier this year the Amex Plat credit was triggered by a $56 fare difference on top of a $200 Delta e-cert and a $225 additional collection for a new ticket where I had used a credit from a refundable ticket. That one triggered the remaining $143 of the credit. Paying with some type of e-cert and then using the Amex for the remaining amount under $250 seems to do the trick.
That may be why someone in another thread today was asking about a cheap refundable ticket with no city in mind.
