Routings BCD → SGN

These are computed routings, not a flight schedule. We work out which airlines could carry the pair from their hub networks, and estimate block time from great-circle distance at 850 km/h plus 8 hours of hub ground time for a transfer. There are no flight numbers, departure times or prices here because we do not have a schedule or rate feed yet — live capacity and pricing arrive with the air-cargo marketplace integration. Confirm any cut-off or connection with the carrier.
