Interesting; RCI have told me that they are not offering city centre transfers this year; they only have busses from
the airport - so you may want to check that?
RCI should, and I’m still awaiting confirmation that they are (otherwise everyone is stuck!), offer a shuttle to Ravenna train station, and you can catch a train to Bologna from there.
From Bologna station there is a mono rail link straight to the airport

Be aware that there are very few cabs in Ravenna.
However friends have used this company ( the lady is English so no language issues) and recommend them highly. They use subcontractors for the Ravenna/Bologna route but the are vetted!
