Expertflyer is showing "P" Class (first) available on Jan. 9, TLV - EWR. I'm calling AA to book this via my Advantage miles and they cannot confirm availability. I know that LY does not sell First on certain flights, but then what exactly does "P" class represent.

The date is a Sunday night - can anyone give me some insight as to the chance of award seats opening on either of the midnight flights to EWR/JFK?

Thanks
