As far as I know, there's the option of making your ticket flexible by paying the fare difference plus 15 EUR. I've never needed to do so, but at least in the early days of "Sparpreis", this was an option. But even if this possibility is still available, this will hardly be an option if you are likely to miss the connection (and I would NEVER buy a Sparpreis ticket if I'm to arrive by plane, unless I have several hours of layover) and if ticket prices are low. As far as I understand, the fare difference to Normalpreis will be less than those 15 EUR of penalty for upgrading your ticket from Sparpreis to Normalpreis.
