I built an open source travel hacking toolkit with sweet spot data, transfer partner maps, and multi-program award search

I spent a weekend building a toolkit that lets an AI agent plan award trips for you. It searches availability across 25+ programs, pulls your balances, compares cash prices, and cross-references sweet spots and transfer partners.

It has three parts:

• 6 data files (JSON) with sweet spots, transfer partner mappings, partner award coverage, alliance membership, points valuations, and a hotel chain lookup. The sweet spots file has actual mile costs, booking phone numbers, hold policies, search tips, surcharge estimates, and which websites to check for availability. ANA F via VA at 72.5k OW, Korean Air J to Europe at 80k RT, Iberia J to Madrid at 40.5k OW off-peak, Hyatt all-inclusive at 20-35k/night, and more.
• 7 skills that give AI coding assistants (Claude Code, OpenCode, etc.) the ability to search Seats.aero across 25+ programs, pull AwardWallet balances, check Google Flights cash prices for cpp comparison, search Booking.com hotel pricing, query Duffel for real airline fares, find weird attractions on Atlas Obscura, and search Scandinavian transit routes.
• 6 MCP servers for Skiplagged (hidden city flights, hotels, rental cars), Kiwi, Trivago, Ferryhopper, Airbnb, and LiteAPI hotel search. These plug into the same AI assistants and give you live pricing across sources.

The whole thing works together. You tell your agent "find me J class to Scandinavia in August for 2 people" and it searches availability, checks your balances, compares against cash prices, and tells you the best option. The sweet spots file saved me from booking Flying Blue at 127k OW when I could have used Korean Air SKYPASS at 80k RT for the same SkyTeam metal.

I built it because I was planning a 3-week Scandinavia trip in business class and got tired of manually cross-referencing everything across programs.

The data files also work as standalone reference if you just want to grep "what transfers from Chase UR" or "cheapest J to Europe."

Everything is current as of March 2026. PRs welcome if you spot something stale or have more ideas to add.
