SKILL.md215 linessingle file

Transfer Partner Optimizer

Given award flight prices (from seats.aero or manual input) and your transferable point balances, find the cheapest path to book.

No API key needed. Uses local JSON data files.

Data Files

File	Purpose
`data/transfer-partners.json`	Credit card → loyalty program transfer ratios
`data/points-valuations.json`	CPP valuations per program (floor/ceiling from TPG, UP, OMAAT, VFTW)
`data/partner-awards.json`	Which programs can book which airlines

When to Use

User has award availability (from seats.aero cached search, live search, or manual input)
User wants to know "which of my points should I use?"
User wants to compare the effective cost across their transferable currencies
User asks about transfer partners for a specific airline or program

Workflow

Step 0: Check Current Transfer Bonuses (Always)

Before recommending any transfer, load the transfer-bonuses skill and check data/transfer-bonuses.json for active bonuses on the relevant currency-to-program pair. A 30% bonus turns a 1:1 ratio into 1:1.3, which can flip the cheapest-currency calculation in Step 3 entirely. Bonuses also have expiration dates that affect timing decisions.

Step 1: Get Award Availability

Use seats.aero (API or web) to search for award flights. Each result includes:

Source (the loyalty program: "united", "aeroplan", "flyingblue", etc.)
Points cost per cabin (e.g., 55,000 business)

Step 2: Map Seats.aero Sources to Transfer Partners

Seats.aero source names map to transfer-partners.json keys:

Seats.aero Source	Transfer Partner Key	Programs That Transfer In
`united`	`united`	Chase UR (1:1), Bilt (1:1)
