Chase Travel

Chase Travel Portal Search

Search the Chase Ultimate Rewards travel portal for flights and hotels via Patchright. Returns cash prices, UR points pricing, Points Boost offers, and Chase Edit hotel benefits.

Requires Patchright (undetected Playwright fork). Chase blocks standard Playwright and agent-browser.

Must run headed (headless=False). Chase detects headless browsers. On macOS, a Chrome window briefly appears. For background operation, use Docker.

Prerequisites

pip install patchright && patchright install chromium

Or use Docker (no local install needed):

docker pull ghcr.io/borski/chase-travel:latest
# or build locally:
docker build -t chase-travel skills/chase-travel/

When to Use

• Compare UR portal pricing against cash and award prices
• Check Points Boost offers (1.5x to 2.0x cpp on select bookings)
• Find Chase Edit hotels with $100 property credit + daily breakfast
• Compare pay-with-points vs transfer-to-airline value

When NOT to Use

• Completing purchases. Find flights and hotels only. Do not book.
• Non-Chase cards. This skill requires a Sapphire Reserve or Sapphire Preferred card.

Card Selection

The script automatically selects the Sapphire Reserve card from the account selector (dynamic Points Boost pricing on travel; ~1.5-2.0 cpp typical on CSR but not a guaranteed floor; Edit hotels). Falls back to Sapphire Preferred if no Reserve found. Only these cards show Edit hotel benefits and travel portal pricing.

Record Mode (API Discovery)

Capture network traffic during a manual search. Useful for debugging or discovering new API endpoints.

# Local only (needs interactive browser)
python3 scripts/record_search.py

2FA Flow

Chase uses SMS or mobile-app push for 2FA (some accounts offer only push). On first login, you must complete 2FA manually. After that, device trust persists (2FA skipped on subsequent runs from the same profile). The script auto-detects which method the account offers and takes the matching path.

How it works: When 2FA is triggered, the script prints one of two sentinels to stdout, then polls for up to 3 minutes:

• 2FA_CODE_NEEDED — SMS. Chase texted a code; provide it (below).
• MOBILE_APP_APPROVAL_NEEDED — mobile-app push. There is no code; the user approves the sign-in in their Chase mobile app, and the script continues once the page clears.

For agents (SMS): When you see 2FA_CODE_NEEDED, ask the user for the SMS code Chase just sent to their phone. Once they provide it, write it to the code file:

echo "12345678" > /tmp/chase-2fa-code.txt

The script picks up the file automatically and continues login.

For agents (mobile push): When you see MOBILE_APP_APPROVAL_NEEDED, tell the user to approve the sign-in in their Chase mobile app — there is no code to enter. The script polls for up to 3 minutes for the approval to land, then continues.

Command hook (optional, for full automation): Set CHASE_2FA_COMMAND to a command that blocks until it has the code, then prints it to stdout. The script runs this instead of polling the file. (Applies to the SMS path only.)

Docker: Use -v /tmp:/tmp/host to share the temp directory. The script checks both /tmp/host/chase-2fa-code.txt and /tmp/chase-2fa-code.txt.

After first successful login with device trust, 2FA is skipped on repeat runs.

Credentials Must Be Resolved Values

CHASE_USERNAME/CHASE_PASSWORD must contain the actual username and password when they reach this script. If you keep secrets in a secret manager, resolve the references into the environment before launching (most managers ship an exec/run wrapper for exactly this).

An unresolved reference (a literal scheme://vault/item placeholder) gets typed into the login form, and Chase answers "We can't find that username and password. Try again." — which is easy to misread as bot detection. (It isn't: fresh automated logins from Docker work fine with real credentials, verified live July 2026, including when saved cookies have expired.)

The script fails fast on both forms of this mistake: it prints CHASE_BAD_CREDENTIALS to stdout (and writes BAD_CREDENTIALS to the 2FA status file) when a credential still looks like a secret reference, or when Chase reports the username/password as not found. For agents: don't retry on this sentinel — fix how credentials are injected, then rerun.

How It Works

Flight Search Architecture

1. Auth: Patchright handles login, 2FA, cookie persistence, and card selection. Account identifier auto-extracted from portal URL.
2. Session: POST to v1/session/create establishes the CXL travel session. Identifiers auto-extracted from cookies.
3. Search API: POST to Chase's internal CTE API creates a flight search session (returns sessionId)
4. Results: Browser navigates to travelsecure.chase.com/results/flights/outbound?ssid={sessionId}&cnxtoken={redirectionToken}. Script intercepts API responses via page.on('response') to capture legwiseResults JSON
5. Pagination: Shadow DOM "Show more" button (<orxe-button>) clicked via JS to load all flights (10 at a time)
6. Points Boost: Shadow DOM toggle (<orxe-toggle class="points-offer">) activated. Boost card carousel parsed for discounted point prices

Hotel Search Architecture

1. Search API: POST to Chase's hotel search endpoint creates session
2. Results: Browser navigates to results page. Script intercepts hotel/v1.0/search/results API responses
3. Edit Detection: Hotels with prm[].c == "Signature Amenities" are Edit properties. Benefits extracted from embedded JSON
4. Boost Detection: Hotels with rwd[].rdp.rcm.t.ofr.d == "Points offer applied" have Points Boost
5. Pagination: Same shadow DOM pattern as flights

Data Structure

Flight results include:

• Cash price, points price, and cash+points hybrid pricing
• Points Boost offers with original vs boosted point costs
• Fare family (Economy, Basic Economy, Business Standard, Business Flex, etc.)
• Flight segments with carrier, times, duration, stops, equipment
• Refundability and change policies

Hotel results include:

• Cash price per night and total
• Points price
• Edit program membership with specific benefits (breakfast, credit, upgrade)
• Points Boost availability and rate
• Star rating, address, amenities, refundability

Output Format

Always use markdown tables.

Flights

Hotels

After Tables

• Note which hotels are Edit (include benefits)
• Calculate CPP for points redemptions
• Flag Points Boost offers with effective cpp
• Compare against direct booking prices when possible
• Pull the actual Points Boost quote at checkout. CSR pricing is dynamic, not a fixed multiplier.

Portal Pricing Notes

• Chase portal pricing on CSR is dynamic Points Boost. The historical static 1.5x multiplier is gone. Each booking quotes a specific points price; effective cpp typically falls in the 1.5-2.0 cpp range on CSR but is not a guaranteed floor on every booking.
• Points Boost offers appear as separate cards with discounted point prices (typically 1.5x to 2.0x cpp effective).
• cash_plus_points pricing uses all available UR points plus cash for the remainder.
• Chase sessions don't persist across browser close. Every Docker run needs fresh login (but 2FA is skipped if device is trusted).

Environment Variables

Troubleshooting

• "Access Denied" on login page in Docker: Chase blocks secure01ea.chase.com from Docker. The script uses chase.com homepage login instead (different auth endpoint, works in Docker).
• Video modal blocks clicks: Script includes a MutationObserver that auto-removes the modal. If it persists, the observer handles re-renders.
• CSRF errors on direct API calls: The travelsecure.chase.com results API requires CSRF tokens managed by the React app. The script uses response interception instead of direct API calls, which sidesteps CSRF entirely.
• No flights found: Chase may not have loaded results yet. The script waits for the API response via interception, so this shouldn't happen. Check if login succeeded.

Limitations

• Headed mode required. Chase detects headless. Docker+xvfb is the workaround.
• ~30 seconds per search. Login + portal navigation + search + results load.
• Sessions die on browser close. No persistent sessions. Every run needs login (2FA skipped after first trust).
• React controlled inputs. Form automation is unreliable. The script uses API calls for search creation, not form filling.
