Not yet. I have tried waitlisting F for one flight in Standard award (which ended few days ago) and both flights in Choice award (which will end soon).
The 1st one didn't clear and the latter 2 are still on waitlisting.
Have tried searching F award flights again for these 2 flights and both award options are still for waitlisting only as usual.
By now, only the J booking on 883 is confirmed.
