Your tier cycle starts when you join the loyalty program and goes on for 12 months unless your current tier is upgraded. If upgraded, the new tier cycle will get extended for 12 months, ending after 12 months from the date of upgrade. The tier end date is also known as your tier expiry date.
E.g. I joined the loyalty program on 1 Jan 2023 and got upgraded to Silver on 20 Mar 2023.
- Original tier cycle: 1 Jan 2023 to 31 Dec 2023 (12 months or 365 days).
- New tier cycle after upgrade: 20 Mar 2023 to 19 Mar 2024 (12 months or 365 days; assuming no further tier upgrades in this period).
