It was a ~30 minute cog test when I took it 4 years ago. Guess it could have changed by now.

Last flow pilots this year will be leaving in/around August. Then it should** start back up again around March of 2015 dumping an additional 25%(or more as rumored) off the list until all flow pilots are gone by early 2016. Any FO hired today should be upgrading in appx 2 years - less if we get more flying - more if Delta stops hiring.
