General rule: airlines and hotels are tight with their top level. You've earned US CP, but that by itself won't automatically translate to 1K, ExPlat, etc. Likewise, HH Diamond can't automatically be turned into MR Plat, etc.

Hotel programs throw around their low and mid levels for free. Just read the boards. If you need a midlevel comp on another airline, you can probably get one: again, go to the individual boards. Some airlines claim to play the "once in a lifetime" rule tight, so you might consider whether you really *need* the comp now, whether you could use it better in late 2004 (worst case: you are a US Gold not requalifying), or whether you don't really need it at all.
