If you're more comfortable choosing yourself which emails to send to TripIt you can turn off Auto Import at any time. 

1.  Go to About You under Settings. 

2.  For the account you'd like to stop scanning for new travel plans, click the "Deactivate" link.

3.  Confirm that you want to deactivate. 

TripIt will stop importing emails from this account immediately.

You can also view and revoke access directly from your Google account settings
