Hi Everyone, the Chase Twice-The-Miles bonus don't post at the same time your base ShopOnePass miles post to your account. That much you've figured out the hard way!

Here's how it works. Once we've received the authorization to post miles from the ShopOnePass merchant, we have a separate verification process for posting the Chase bonus miles that runs at set intervals. As a result, you can expect your Twice-the-Miles bonus to post 1-2 weeks after the initial base miles appear in your account.

Edited to add: As G2244 mentioned, the process of posting these bonuses hasn't started up yet, but should within the coming week. Sorry for the delay.
