Okay, so you'll be protected, if you miss the Vienna flight AF will put you on the next one. You should check in as normal
The Accra flight arrives in terminal 2E and the Vienna flight from 2F. Follow the signs for connecting flights to 2F, you may need to take a train within 2E first then you walk from 2E to 2F and clear Schengen immigration on the way
No escort from ground staff unfortunately
