When do JPMiles expire?
JPMiles are valid for a period of 13 quarters including the quarter in which they were earned. Accordingly, A year is divided into 4 quarters and JPMiles earned in a quarter will expire on the last day of the 13th quarter from that date. E.g. JPMiles earned by you in the 1st quarter of 2008 (Jan-Feb-Mar) will expire on the last day of the 1st quarter of 2011 (i.e. March 31, 2011). The validity of JPMiles cannot be extended. JPMiles not redeemed before expiry will lapse.
