Your Skywards Miles are valid for at least three years from the date in which you earned them. Within the calendar year that Skywards Miles are due to expire, Skywards Miles will be removed only at the end of the month in which you were born. You can set up automated messages from your My Account page to remind you when your Skywards Miles are due to expire.
Additionally, Skywards Miles belonging to Platinum members will not expire for as long as they retain their Platinum tier status. Please refer to the Emirates Skywards Programme Rules for complete details.
