I"m looking at EY867 PVG-AUH. Per their booking site, it says a 787 is used. When I check the First class, it shows it as sold out. When I check Seatguru, it says 787 has F. experflyer is not able to pull up a seat map for F. The business class seat map started from row 5.

Is F not offered on this flight or there's a version without F?
