Bilt publishes its full transfer partner list, with every ratio, on its support centre. Twenty-five programs: eighteen airlines and seven hotels. All but two transfer at 1:1 — Accor takes three Bilt points for two ALL points, and I Prefer pays two of its points for every one of yours.
The minimum depends on status. Blue members must move at least 2,000 points; Silver, Gold and Platinum members can move 1,000. Every transfer goes in 1,000-point increments and cannot be reversed once made.
Transfers are immediate in most cases, and Bilt asks members to allow up to 48 hours — up to 72 for Southwest. Bilt notes that participating partners are subject to change and that it sometimes runs promotions at varying transfer rates.
