Flight Search Strategy
Search ALL Sources for EVERY Flight Search
This is not a pick-one list. Each source returns different results, different prices, and different airlines. Missing a source means missing options. The priority order determines which price to trust when sources disagree, not which sources to skip.
| Priority | Source | Strengths | Blind Spots |
|---|---|---|---|
| 1 | Duffel (skill) | Most accurate cash prices. Real GDS per-fare-class data. Bookable. | No Southwest. No award pricing. Offers expire in 15-30 min. |
| 2 | Ignav (skill) | Fast REST API. Market selection for price arbitrage. Free. | No Southwest. No award pricing. |
| 3 | Google Flights (skill, agent-browser) | Covers ALL airlines including Southwest cash prices. Free. Economy/business comparison. | Prices can be inflated vs GDS. No points pricing. |
| 4 | Skiplagged (MCP) | Hidden city fares. Zero config. | No Southwest. Can be noisy on small markets. |
| 5 | Kiwi.com (MCP) | Virtual interlining (creative cross-airline routings). Zero config. | Returns garbage on small markets. No Southwest. |
| 6 | Seats.aero (skill) | Award flight availability across 25+ programs. The crown jewel for points. | Cached data, not live. No cash prices. No Southwest. |
| 7 | SerpAPI (skill, optional) | Google Hotels search. Destination discovery (Google Travel Explore). | NOT for flights (inflated prices). Hotels and "where should I go?" only. |
| 8 | Southwest (skill, Patchright) | Fare classes, points pricing, Companion Pass. All 4 fare classes, cash + points. | Pre-built Docker image: ghcr.io/borski/sw-fares. Or local Patchright (headed mode). ~20s per search. |
