Final answer:
The airline industry has grown, with more efficient flights and expanded hub-and-spoke systems, indicating frequent flights. Delta Connection likely operates a significant number of flights at the world's busiest airport with an average of 2,500 daily movements.
Step-by-step explanation:
The specific number of flights that Delta Connection operates per day is not provided in the given information, so an exact figure cannot be accurately provided without access to up-to-date statistics.
However, considering the information about the industry as a whole, it is clear that the airline industry has grown substantially since the deregulation era, with more efficient flight capacities and expanded hub-and-spoke systems. This has led to increased flight frequency and more available jobs in the sector.
Looking at the data on hand, scientists found that the busiest airport in the world averages 2,500 arrivals and departures each day.
Since Delta Connection is a significant airline, it is reasonable to assume that they operate a substantial proportion of these flights, although the exact number would fluctuate daily based on demand, scheduling, season, and other variables.
