How TripFit works

Methodology, for anyone who wants the detail. TripFit is an affordability engine, not an itinerary planner.

Price Truth Engine

Deterministic math on airfare, baggage, room, mandatory fees and taxes. The model never invents or calculates a price.

Two-agent pipeline

The Search & Assembly Agent builds candidates; the Pre-Booking Verification Agent refreshes them — and never books.

Similar destinations

If your destination doesn't fit, comparable destinations that do fit are surfaced with supporting evidence.
