I'm not worried about my checked bag because I have a 20 hour overnight in Paris, so I think my bag will catch up in Paris before I fly to Berlin, and I'm planning to check it all the way thru, anyway.

What I'm hoping to do, is, I currently have a double connection before my TATL. The middle flight is nearly sold out. If I get the VDB, I want to go from the first flight to a different TATL flight to CDG from the first hub, and skip the second flight.
