Bilt Travel Portal Search

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

What this means for the toolkit:

• For cash-only flight searches, prefer the duffel skill. It uses an authenticated Duffel API key, returns the same data faster, and supports more parameters (multi-city, time windows, max connections, supplier_timeout tuning).
• For Bilt Points context (CPP, comparing portal cost to award alternatives, Bilt redemption math), use this skill. The points pricing is exclusive to Bilt's endpoint.
• For Home Away From Home property research, use this skill. The isHafh flag is Bilt-specific and surfaces the $300+ benefits properties.

Why It Matters

• 1.25 cpp standard redemption rate on Bilt Points (1 USD = 80 points). One of the better fixed portal rates.
• Home Away From Home (HaFH) is Bilt's premium hotel program. Gold and Platinum members get $300+ in benefits per stay (daily breakfast for two, $100 property credit, room upgrades on arrival, early check-in / late check-out, dedicated Virtuoso Travel Advisor).
• Bilt Points transfer 1:1 to Hyatt, Marriott, Hilton, IHG, United, AA, Air Canada Aeroplan, Air France/KLM, Virgin Atlantic, Cathay, Turkish, and more — so this portal is a 1.25 cpp "bottom-of-the-barrel" comparison point for transfer-partner award searches.
• Flights are Duffel-backed. Same response shape as the duffel skill. Same airlines, same fare classes, same segment structure.
• No auth needed for search. Browser automation, login, 2FA all unnecessary. Just curl.

When to Use

• Comparing Bilt portal pricing to seats.aero awards
• Computing CPP for Bilt Points redemptions
• Finding HaFH properties for Bilt Gold/Platinum benefit stacking
• Sanity-checking cash vs points decision when Bilt Points are involved
• As a "redemption floor" reference: if award flights cost more than the portal price, the portal wins
