Surprised that my SWU request for late April DFW-PVG round trip was cleared 3 months before the flight. I requested the SWU in the early this month and I was checking the EF once a while to see if any C inventory has been released for DFW-PVG, however my SWU was cleared without the C alert from EF. This is a first for me as in the past the TPAC SWU upgrade was always clear at the T-26 or later for me before this trip.
