How to reach Miles+Bonus Silver
Miles+Bonus Silver requires 12,000 Tier Miles. Star Alliance.
Threshold
| Tier Miles required | 12,000 |
| Next tier (Gold) | 36,000 Tier Miles |
Tier Miles reset to zero after each tier is reached — the threshold shown is earned toward that tier from the previous level.
Tier miles are counted from each tier-upgrade date (Gold needs a further 24,000 after Silver). Mandatory Aegean/Olympic Air flight minimums apply at each tier and rise from 5 Nov 2026, when a new Platinum tier (a further 72,000 tier miles + 32 A3 flights) also launches.
