Well, SR operated the first morning ZRH-LHR with an MD-11 for a long time. Now is is usually an A321, but also sometimes an A330. The same used to be true for the first flight in the morning from ZRH to MUC, while it was a code share with AA. I suppose they took part of the seats. Weird flying in "First" on a 40-minute flight.
