I'd like to be able to forward specific emails (identified via a Filter) to my TripIt account for points tracking. It seems as if the only way to auto-forward in Gmail is if you own the email address you want to forward to, and can provide verification.

IFTTT.com might serve as a useful proxy. If you allow the service to access your gmail, it will effectively create a new email for you and send it to points@tripit.com when it receives an incoming email from a specified server.
Luckily, it seems AA, United, Southwest and others have fairly non-generic emails for their monthly statements which should help (and separate spam emails with point bonuses which can confuse the point tracker).
