Unlocking an Air Miles Cash account in 2026 usually requires a quick security verification through the official Air Miles mobile app or website. Most accounts are "locked" as a safety feature to prevent unauthorized redemptions. To unlock, log in to your profile, navigate to the "Account Balance" or "Settings" section, and look for the "Lock/Unlock Cash Account" toggle. You will likely be prompted to enter a one-time verification code (OTP) sent to your registered email or phone number. If your account remains locked due to "suspicious activity" or multiple failed login attempts, you may need to contact the Air Miles Customer Care center directly via their live chat or phone line. It is a high-priority recommendation to keep your account locked whenever you aren't actively using your miles at a checkout, as this "digital safety" measure is the best defense against mileage theft in 2026.
