Example, if you previously applied for AMEX *wood in 2005 and received 4K sign-up bonus, you would be able to apply again and get 2k bonus. If you are still a current card holder, don't know if you have to cancel existing card first. This is based on FT threads that I have read on this subject.

As an alternative, try the following. When I signed for AMEX *wood, sign-up bonus was 4k, and I was not aware of 6k offer when I signed up. After second statement, I called AMEX and asked about 6k bonus, and they gave me the difference without any argument. ^

You may need to have some spend for them to give up the extra points, though.
