Was scheduled to fly MUC-CDG-ZRH on Air France (ticketed/marketed). The check in agent put me on the nonstop MUC-ZRH on Swiss, for fear I'd miss the connection in CDG. I was able to call Delta later that evening and request the original routing credit for the Air France flight, and they immediately put it into my Skymiles account. All they needed was my ticket number. I also received United miles for the Swiss flight.
