Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.02163 |
| Opus 5 | $0.00016 | $0.01081 |
| Sonnet 5 | $0.00006 | $0.00433 |
| Haiku 4.5 | $0.00003 | $0.00216 |
Grade A, and why
booking-guidance scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Booking Guidance
Finding the deal is half the battle. Telling the user how to actually book it is the other half. Every recommendation should include a booking path.
Reference data: data/alliances.json has booking details for major programs in key_booking_relationships.
Program Fee Profiles
Check this before recommending a transfer or locking in a departure city. Fees vary dramatically by program and origin airport and can add $100-700+ per person on top of the miles cost. Two things to keep in mind reading the table: (1) several programs are surcharge-free on their own metal and most partners but pass heavy surcharges on specific partners (notably British Airways metal) — the YQ column calls those out; (2) dollar figures are per direction and scale with cabin — economy surcharges are materially lower than the business-class figures shown for surcharge-heavy metal. Rows marked ⚠️ are high-surcharge programs that often lose to cash.
| Program | YQ Surcharge? | Typical fees/pp | Notes |
|---|---|---|---|
| Aeroplan (Air Canada) | No | $50-100 | No YQ pass-through on Star Alliance partners. Low fees. Best for LH/LX/UA awards. |
| Flying Blue (AF/KLM) | Yes | ~$250-400/way economy, ~$489-600/way business, ex-CDG | AF passes full fuel surcharge; France adds heavy departure tax. Worst from Paris. |
| United MileagePlus | No | $50-100 | No YQ on most partners. |
| Virgin Atlantic | Yes (on VS metal) | Cabin-dependent: ~$150-300/way economy, ~$500-700/way Upper Class; low on Delta metal | Surcharges scale with cabin. Delta metal carries surcharges US↔UK specifically. |
| Turkish Miles & Smiles | No on UA/Turkish metal; YES on Lufthansa Group (LH/LX/OS/SN) | $20-50 (own/UA metal) | Extremely low on own/UA metal. Book by phone (online unreliable). Dec 2025 devaluation. |
| British Airways Avios | Yes | ~$200-400/way economy, ~$400-700/way business, BA long-haul metal | Notorious surcharges on BA metal. Use short-haul, or partner metal (AA/Alaska/Qatar), instead. |
| American AAdvantage | No on own metal + most partners; YES on British Airways & Iberia | $50-75 base; on BA/IB metal ~$200-400/way economy to $400-700+/way business | Surcharge-free on JAL/Cathay/Qatar. Route partner awards away from BA/Iberia metal. |
| Alaska / Atmos Rewards | No on own metal + most partners; YES on British Airways, Icelandair, Hainan | $25-75 base; on BA metal ~$150-400/way economy up to ~$1,000/way premium | Renamed from Mileage Plan (Aug 2025). Surcharge-free on Cathay/JAL/Qantas/Condor/Fiji. |
| Avianca LifeMiles | No | ~$25/ticket | No-YQ Star Alliance program. Predictable total even on ANA/Lufthansa/Swiss metal. |
| Iberia Plus (Avios) | Low (far less than BA) | ~$150-200 RT transatlantic business | The transatlantic Avios sweet spot: MAD-US business ~40.5K-59K Avios/way with modest surcharges. |
| JAL Mileage Bank | No on JAL metal | from ~$20 | Cheap distance-based partner chart. Partner metal (e.g. BA) may add YQ. |
| Qatar Privilege Club (Avios) | No fuel surcharge on Qatar metal | ~$30-100 per-segment fee | Excellent Qsuites value. Per-segment cash fee returned in 2025. |
| Delta SkyMiles | No | No award fees | Dynamic award pricing is the real cost, not fees. |
| ⚠️ ANA Mileage Club | Yes — heavy | ~$95-185/way US-Japan YQ | Round-trip booking only; no awards within 96h of departure. |
| ⚠️ Cathay / Asia Miles | Yes | High on long-haul; hiked again in 2026 | Passes full carrier-imposed surcharges. |
| ⚠️ Emirates Skywards | Yes — heavy | Among the highest YQ of any program | Surcharges often kill the redemption vs cash. |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 11d ago First seen · 102 lines · 32 tokens per session scan A 6b453f4273f5
booking-guidance is a skill published in the GitHub repository borski/travel-hacking-toolkit (659 stars, last pushed 3d ago), licensed MIT. It adds 32 tokens to every session and 2,163 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
