Students often ask me which usage correct, either he is older than me or he or he is older than I am....Which one is correct???? This is the answer...
a) She/He is older than me.
b) She/ He is older than I am.
c) I'm older than her.
d) I'm older than she is.
the four aforementioned usages are the most correct usages. So make sure you say 'am' if you end your sentence with 'I'.
