This morning, I was scheduled to go SDF-CVG-PHX. The SDF-CVG segment was oversold by 1, so I took the bump. They started off by offering me $200 for a flight arriving 6 hours later than originally scheduled. I was able to successfully counter by asking for $400, but the GA had to call "Global Services" to get an authorization code. Also said $600 was not allowed.

My later flight, SDF-ATL-PHX, was also oversold out of SDF. The GA ended up having to send me over to CO. He was unable to get the computer to give me a $400 voucher, so had to print out 2 x $200 vouchers.

I thought that the new policy was supposed to be $400 minimum, and $600 for over 4 hours. Is that not correct? Or is this another new policy that someone else has experienced?
