Tier Credits
Elite-Qualifying Tier Points/Credits
Definition
Status credits earned through flights, separate from frequent-flyer miles (which are for redemptions). Determine annual elite-status qualification.
Why it matters
Most US airlines (Delta, United, American) renamed traditional 'elite-qualifying miles' to a dollar-based credit (MQDs, PQPs). Status-chasing is more about spending than flying now. Foreign carriers (Star Alliance, oneworld) still mostly use mileage-based status.

Elite Status
Higher tiers of airline or hotel loyalty programs earned through annual spending or stays. Provides perks like upgrades, lounge access, bonus miles, and waived fees.
Status Match
When one loyalty program grants you equivalent status based on your status with a competing program. Often time-limited and requires a 'challenge' (spend or stays) to keep.
Expiring Points
Most airline and hotel programs expire points after 18-24 months of inactivity. A single qualifying transaction (purchase, transfer, redemption) extends the clock.
