huh?? Premier Miles is supposed to be a miles card i.e. for ppl whom travel by air. How come got limitation vs their plat... 

I used to enter LCCT PPL whenever I'm in LCCT. Be it I'm flying or waiting for arrivals. Most of the time I just enter with NRIC.
Sometimes they asked for boarding pass, sometimes they don't. When they ask for boarding pass, I just casually tell them I have not checked in yet although I'm not flying
