My CFI renewal is due this month, (I procrastinated...AGAIN) and I'm going to spend the weekend doing an online course to renew it. I used AOPA a couple years ago and managed to get it done in a weekend. I noticed King Schools is doing an online course now, as well as American Flyers, Gleim and all the other major aviation companies. Do you guys recommend anyone else other than AOPA? I know this probably sounds bad but I am looking for the easiest and most convenient route. I only have a few free days to get it done, and I'm not an active CFI, I just don't want my certificate to lapse.
