I recently finished renewing my flight instructor certificate online (I heartily endorse the Jeppesen program, by the way), which got me to thinkin' - something I don't do very often.
How many of you have kept your Flight Instructor credentials current since you've become airline pilots? If you are keeping them current, do you do it online or via a live Flight Instructor Refresher Clinic? For you CAs out there: how many of you keep yours current based on captain's duties?
