Thanks to everyone for posting the qualification requirements for Centurion.

Looks like I'd qualify - so I'm deciding whether the make the jump from Platinum.

I know the cost is $2500 vs $395 annually. How much are extra Centurion cards?

In terms of incremental benefits from Platinum, I'm aware that Cent offers

(1) 2nd-level elite status on DL, NW and CO
(2) $500 cruise onboard credit (vs $300 on Plat)
(3) Use of CTS - but which isn't meaningfully different than PTS

Other than these and the "prestige factor" of the card, are there any other incremental benefits from Platinum?
