Just bring the ikad and the letter from your uni stating your passport is in renewal process and contact number emergency of uni representative in case road block. In my case Penang no need passport but just bring your ikad just to be sure.
Sighhh Penang is domestic flight they dont require passport but just to be sure Ikad is not a passport replacement but act as it because students bringing passport everywhere will risk getting passport stolen or misplaced. Hence they issued an ikad act as an identification for intl students without having to bringing passport everywhere.
@julia_7 The passport is still required for any travel via flight. The iKad does not replace a passport. If the passport is required for verification or identification, the student is required to produce the passport.
