United Starlink Tracker

Use when the user asks "does my flight have Starlink/WiFi?" with a specific United Airlines flight number and date. Returns YES if the published aircraft assignment is a plane verified to have Starlink, LIKELY YES if that plane is listed as Starlink-equipped but not yet verified, NO if it is a plane verified to have other WiFi, or a probability estimate if no assignment exists yet (assignments publish ~2 days out). An assignment can still change through an aircraft swap. For dates further out, call predict_flight_starlink directly — check_flight just falls through to the same estimate with extra latency.

Use when the user asks "how far along is the Starlink rollout?" or wants overall fleet numbers. Returns United Airlines Starlink installation counts and percentages across mainline and express fleets, plus a per-aircraft-type breakdown (installed/total per family). Not for per-flight checks — use check_flight for that.

Takes no parameters.

Use when the user asks about the planes themselves — "which tail numbers have Starlink?", "which aircraft types are equipped?". Returns United Airlines tail numbers, aircraft types, operators, and install dates (default 50 most recent; pass limit up to 500). Not for finding flights — use search_starlink_flights for that.

Use when the user asks "will my flight have Starlink?" for a date too far out for a confirmed assignment, or with no date at all. Returns the probability that a United Airlines flight number gets a Starlink plane, from historical observations. Reliability varies: high-confidence (5+ obs) is the most reliable tier but is not a guarantee; low-confidence (0-1 obs) is just the fleet prior. UA1-2999 (mainline) has materially lower coverage than UA3000-6999 (express) — call get_fleet_stats for the current split rather than assuming a rate.

Use when the user asks "what's the best way to fly X to Y with Starlink?" or wants ranked alternatives. PRIMARY TRAVEL-PLANNING TOOL — multi-stop search (up to 2 stops default, 3 max) ranked by COVERAGE RATIO (expected Starlink hours / total flight hours) so a 92% 1h direct scores the same as a 92% 10h multi-stop. Direct flights always shown first. Returns probability-ranked routings, NOT bookable itineraries — connection timing isn't validated; verify on the airline's site.

Use when the user asks "which flights between X and Y have Starlink?" or "what Starlink flights serve airport X?". Single-route lookup: returns United Airlines flight numbers on a route (or touching an airport) ranked by Starlink probability. Pass both origin+destination for a specific route, OR just one to list all Starlink flights from/into an airport. For trip planning with connections, use plan_starlink_itinerary instead — this tool has no connection logic or coverage-ratio ranking. Empty result = route not served by Starlink planes.

Use when the user asks "what Starlink flights leave from X tomorrow?" or wants scheduled near-term departures. Returns flights in the next ~2 days whose currently assigned aircraft is Starlink-equipped (verified or listed) — a published assignment, not a prediction, though an aircraft swap can still change it. Pass at least one of origin or destination (both narrows to a single route). Aircraft assignments aren't published further out, so for later dates use predict_route_starlink or plan_starlink_itinerary instead.
