I'm curious what people's experience has been with an upgrade and amex offers on the card prior to the upgrade? I have an offer on my current card that I'm waiting to use, but am also interested in doing the upgrade they're offering me for the 100k points. Will my offer still be on the new card, or will they wipe the offers clean with the upgrade? I haven't asked Amex yet -- figured I'd ask people who may have actual data points to share.
