Saw EJA990P today. When I asked about the ‘P’, on another forum, someone astutely noted that EJA990 was the same flight(s).
Any ideas what gives?
Discussed here:

And so noted in the “other” forum. 
Pink slipped, see previous discussion.
We integrate the flights so if you look up N990QS, EJA990, or EJA990P you see all the flights for that aircraft.
