What is the current throughput? What is the trend in throughput in the last couple of years? what are the current reasons for throughput being lower than 100%.
What does throughput mean in this context? Number of flights that take off per hour/day et al or passengers management awaiting to board flights or operations related to flights?
What is the objective of increasing this throughput metric? Is this airport being considered to be INTL airport by any chance? Or to add another airline to the existing lineup of airlines.

Lets assume these could be the possible reasons for lower than 100% throughput
1. Flights not taking off on time
2. Flights have landed however still taxing
3. Delay with boarding as staff not able to manage the recent surge in passenger traffic
4. Long check in lines as staff not able to handle a surge in passengers
5. Any recent developments? For example, two or three airplanes added?
6. [Temporary] Workers on strike due to reasons like a strike (urging for fair compensation)
7. [Temporary] Two or three machines at security gate malfunctioning so staff needing to do more work
8. Weather related – like a snow storm delaying flights by almost 72 hours

if we try and analyze #1 and 2, flights not taking off on time can be due to some scheduling errors or inability for the airport’s infrastructure to accommodate more flights. Can figure out what is the ideal number of flights and passengers the airport can accommodate to get to a 100% efficiency. The spill over passengers can perhaps be moved over nearby airports?
