Real-time Google Flights: one-way and round-trip fares over date ranges, with price verdicts.

Deterministic date math agents get wrong, done in code over MCP: business_days adds and counts working days with holiday awareness, meeting_overlap finds shared windows across UTC offsets including half-hour zones, recurrence_expand generates concrete dates, with deadline_planner and sla_due in the premium tier. Every failure mode returns a structured error.
