You discovered: INTERVAL SCHEDULING!

Every flight occupied a stretch of time. Flights could share a gate only when their intervals did not overlap, so you separated every conflicting pair while reusing free gates.

This is interval graph coloring — used to schedule classrooms, hospital rooms, runways, and computer jobs. ✈️
