Even though PLT is superior compared to GLD in status benefits, I got more op-upīs in my 1 year as a GLD than in my 3 PLT years together

But the upgrade window and priority over the GLD members are useful ^

Please note: Within Platinum it is the check-in time for the flight that matters (as far as I have heard) so I always check-in as early as possible, also for stand-by on earlier flights where the same system comes to effect !
