Bilt Travel Portal Search

Search Bilt Rewards travel portal via the public REST API. No authentication required for search. Returns both cash prices in USD and Bilt Points cost for hotels and flights.

Important: Bilt is Whitelabel Duffel

Bilt's travel search is built directly on top of Duffel. All evidence points to a complete white-label arrangement, not a partial integration:

• Flight offer IDs are off_XXX, slices sli_XXX, segments seg_XXX, aircraft arc_XXX, airlines arl_XXX. All Duffel ID patterns.
• Carrier and aircraft logos served from assets.duffel.com.
• Hotel loyalty program logos served from assets.duffel.com/img/stays/loyalty-programmes. So hotels are Duffel Stays.
• JWT organisation_id: org_0000AaALZyFQ... is a Duffel auth pattern.
• Field names match Duffel exactly: marketingCarrier, operatingCarrier, cabinClassMarketingName, fareBasisCode, isNDC, ndcRedirectUrl, totalEmissionsKg, slices[].segments[].passengers[].baggages[].

What Bilt adds on top of Duffel:

• totalPointsRequired (Bilt Points cost at the fixed 1.25 cpp portal rate)
• isHafh (Home Away From Home flag on hotels)
• loyaltyProgram.reference (brand affiliation surfacing for hotels)
• A few Bilt-specific filter fields
