I've taken a few of their Corporate Aviation Management Classes and I start my first class towards finishing my degree this month. It's been a positive experience so. The materials are good and the online stuff is easy to navigate.
The only drawback is cost. I looked into the Thomas Edison progam too, but decided to go with Riddle even though tuition is more. One reason was the fact that Edison charge you for your portfolio evaluation. For some reason that cheapened the whole institution for me so I went with the "name brand" (though I understand that Edison is a perfectly good school). With an ATP, CFI, and air carrier experience ERAU gave me 36 hours credit plus credit for transfer classes.
