Reading the Results

Redeemable Miles Table

Shows the percentage of flown distance you earn as spendable miles.

| Column | Meaning | |--------|---------| | Base | Earning rate with no elite status | | Tier 1 | First elite tier bonus | | Tier 2 | Second elite tier bonus | | Tier 3 | Third elite tier bonus | | Tier 4 | Highest elite tier bonus | | Minimum | Floor (e.g., "500 Miles" means you earn at least 500 regardless of distance) | | Restriction | Limitations (e.g., "Countries Excluded: CU" = no earning on Cuba routes) |

Qualifying Miles Table

Shows the percentage of flown distance that counts toward elite status.

Same column structure. Often different rates from redeemable. Some programs earn 0% qualifying on discounted fares even when they earn redeemable miles.

**Key distinction:** A flight can earn redeemable miles but zero qualifying miles. Always check BOTH tables.

Tier Levels by Program

Programs use different names for their tiers. Map your status to the right tier column:

| Program | Base | Tier 1 | Tier 2 | Tier 3 | Tier 4 | |---------|------|--------|--------|--------|--------| | AA AAdvantage | Base | Gold | Platinum | Platinum Pro | Executive Platinum | | Alaska Atmos | Base | MVP | MVP Gold | MVP Gold 75K | MVP Gold 100K | | Delta SkyMiles | Base | Silver | Gold | Platinum | Diamond | | United MileagePlus | Base | Silver | Gold | Platinum | 1K | | Flying Blue | Base | Silver | Gold | Platinum | Ultimate | | BA Executive Club | Base | Bronze | Silver | Gold | Gold Guest List |

Traveler Profiles

Before using the decision algorithm, define each traveler's profile. You need:

  • Which FF programs they have accounts in
  • Their elite status tier in each program
  • Which program is their "primary" (the one they're actively building status in)

Example profile:

Traveler: Alex
Programs: AA AAdvantage (Platinum, Tier 2), Alaska Atmos (Base), Flying Blue (Silver, Tier 1)
Primary: AA AAdvantage (retaining Platinum status)

**Only recommend programs someone has an account in.** Don't suggest crediting to Etihad Guest if nobody has one, unless the earning is dramatically better AND the program is useful for future redemptions.

Decision Algorithm

When a flight is booked, run this logic to determine where to credit:

Step 1: Gather inputs

  • Operating airline IATA code (from ticket, NOT ticketing airline)
  • Booking class letter (from ticket or fare details)
  • Route distance in miles (estimate or look up)
  • Which traveler(s) are on the ticket

Step 2: Fetch earning rates

  • Fetch `https://www.wheretocredit.com/en/{IATA}/{CLASS}`
  • Extract redeemable AND qualifying rates for all of that traveler's programs

Step 3: Calculate actual miles earned

For each reachable program, for each traveler:

raw_miles = route_distance × (base_rate + tier_bonus) / 100
actual_miles = max(raw_miles, minimum_floor)

If a program uses fare-price earning (e.g., "6 Miles/EUR"), calculate based on ticket price instead of distance.

Step 4: Apply decision rules

**Rule 1: Short-haul floor advantage.** On flights under ~1,500 miles, programs with a 500+ mile minimum floor (like Alaska) can earn MORE than programs offering a percentage of distance. Calculate both and compare. At Base tier, Alaska's 500 floor beats 25% earning on any flight under 2,000 miles. At higher tiers with bonus percentages, the crossover point drops.

**Rule 2: Qualifying miles matter f
