Perhaps you think the guy who pays more for a ticket should get the best service.
Nope.
I just think that it makes no sense to divide pax in boarding zones, assign J class pax a zone of their own (#1), and then lump them together with zone 2 when it actually comes to boarding.
They should make up their minds: either they board zone 1 before zone 2, or they include SP in zone 1.
KL gate agents occasionally realize and acknowledge there's a problem here, e.g. a couple of weeks ago when they invited me to skip the SP line and board first along with those needing assistance.
