Vacation planner · live fare baseline
A Google Flights-style dashboard for the Dec 14–30 family itinerary: Houston to Florianópolis, Florianópolis to Bauru, then Bauru/São Paulo area back to Houston. Long-haul pricing uses 3 paid seats — 2 adults plus the child in her own purchased seat, not a lap infant — with luggage and a hard 16-hour maximum for displayed live itineraries.
Campinas/Viracopos is now the main airport view; GRU stays on the page as the last-resort fallback if VCP pricing or schedules fail.
Last-resort fallback: book the long-haul into GRU, then use separate Brazil domestic legs. Only options at 16 hours or less are included.
Your IAD United idea still looks strong: one reasonable connection to GRU, child gets a seat, and every shown leg stays within the 16-hour cap.
Useful as a benchmark, but many direct-to-FLN options fail the 16-hour family filter; separate GRU + domestic flights is cleaner.
Favorites are your shortlist. Planner is separate and holds one selected itinerary for each required trip leg.

Ranked for price, flight duration, number of stops, and toddler/luggage practicality. Long-haul prices are shown as 3 paid seats: 2 adults plus the child in her own purchased seat; optional baggage and seat fees may differ by airline.
These are the airline sites and policy pages to verify immediately before booking. Fare bundles change quickly, so direct checkout is the final source for bag fees, seat selection, and child-restraint acceptance.
