SFO-SYD late last month had none.

SYD-SFO earlier this month had them, but they were not proactively offered. By the time I asked (a few hours after takeoff), the FA told me she thought they were out of my size but she would go check. She came back to me about an hour before landing, said they did indeed have some but she had forgotten to bring them to me, and offered to give me a pair to take with me...
