Prior art

External standards this shape draws from or aligns with. See Shape design principles for how prior art informs shape design.

• IATA Resolution 753 / Flight Codeshare — Our flightNumber follows IATA carrier-code + digits format (UA 1234). Canonical for cross-carrier flight identity.
• Duffel / IATA NDC Slice+Segment — NDC models a trip (slice) as multiple flights (segments). Our flight shape = NDC segment; our trip = NDC slice.
• schema.org/Flight — Our flightNumber = flightNumber; departsFrom/arrivesAt = departureAirport/arrivalAirport; departureTime/arrivalTime match directly; carbonEmissions ≈ estimatedFlightDuration + emissions extensions.
