On Sunday I made an online reservation for a quick Amtrak getaway on Memorial Weekend out East. In the interim I decided to make changes to that trip, and called Amtrak last night to modify as I couldn't see an easy way for me to do what I wanted to do online and didn't want to mess it up. The agent made those changes to that reservation but when it came to paying for the upcharge, my AGR card was denied, twice. No idea why. I am well below my limit and I pay it off every month so there should be no issues. I called B of A and was told there were no blocks or flags on my account and said it had to be a merchant issue. Called Amtrak back, and they blamed B of A, of course but had no plausible explanation. The agent said don't worry, the reservation is held until my departure date and sent me a new reservation confirmation and barcode to be used at a QuickTrak, but the system would will not produce a new e-ticket until it is paid in full. I've never, ever had a purchase denied. It is flummoxing. Anyone ever have an issue like that?
