Bilt Travel Portal Search

Search [Bilt Rewards](https://www.bilt.com) 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](https://duffel.com). 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](../duffel/SKILL.md). 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](../duffel/SKILL.md). 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

When NOT to Use

• **Cash-only flight searches without Bilt Points context.** Use [duffel](../duffel/SKILL.md) instead. Bilt is whitelabel-Duffel, so Duffel returns the same cash prices and offer shape, faster, with more parameters supported.
• **Booking flights or hotels.** This skill finds offers only. Booking requires login + Bilt Mastercard. Out of scope.
• **Award flight search.** Use [seats-aero](../seats-aero/SKILL.md) for award availability across loyalty programs.
• **Hotel research outside Bilt's program.** Use [premium-hotels](../premium-hotels/SKILL.md) for Amex FHR/THC + Chase Edit, [serpapi](../serpapi/SKILL.md) for general Google Hotels metasearch.

Bilt Points Valuation

| Metric | Value | Notes | |--------|-------|-------| | Portal redemption rate | 1.25 cpp | $1 = 80 points (standard, fixed) | | Cash → points formula | `points = round(usd / 0.0125)` | Reverse-derived from observed responses | | TPG valuation (transfers) | 2.05 cpp | When transferred to optimal partners |

**Decision rule:** If transferring Bilt Points to a partner program would yield more than 1.25 cpp, transfer. If not, use the portal.

API Base

https://api.biltrewards.com/public/travel

All endpoints are public, no API key required. Standard JSON responses.

Hotel Search

Step 1: Look up location searchId

curl -s "https://api.biltrewards.com/public/travel/hotels/auto-complete?query=New+York" \
  | jq '.searchResults[0].locationSuggestion'

Returns:

{
  "name": "New York",
  "country": {"name": "USA", "code": "US"},
  "region": {"name": "NY", "code": null},
  "searchId": "ChIJOwg_06VPwokRYv534QaPC8g"
}

The `searchId` is a Google Places ID. You can also pass `searchType: HOTEL_SEARCH` results to search a specific property.

Step 2: Search hotels

curl -s "https://api.biltrewards.com/public/travel/hotels/search" \
  --get \
  --data-urlencode "checkInDate=2026-08-15" \
  --data-urlencode "checkOutDate=2026-08-18" \
  --data-urlencode "numGuestAdults=2" \
  --data-urlencode "numRooms=1" \
  --data-urlencode "searchId=ChIJOwg_06VPwokRYv534QaPC8g" \
  | jq '.hotelResults | length'

Returns 100 to 200 hotels typically. Synchronous, no polling needed.
