About two weeks ago, I wrote to CO to get comped to Plat, and they comped me to Plat. I used the following from a post as a guide:

Continental

Will match status, generally to equivalent level up to Platinum (top tier)

They seem concerned about fraud, so require a bunch of information:
A copy of your current elite status card.
A copy of your latest elite statement.
A copy of your current One Pass Membership Card.
A copy of your current One Pass statement.

Along with a note explaining you'd like to shift your busy to them if they'll match your current status.

Mail To:
Continental Airlines
One Pass Service Center
Attn: One Pass Match Program
P O Box 4365
Houston, TX 77210-4365

The key is that your EQM on the AA statement must be over 75K for them to comp you to Plat.

I find CO to be far superior in BF and Coach to AA.
