explain these statements: Based on the two inventory control methods we learned about, I would prefer a leg-based inventory control approach using the nested booking structure for a small airline. If passengers need to fly multiple segments in a trip, they will just need to pay for each leg. This will also allow the airline to receive full revenue for each purchased seat on each plane. As a small airline, the route and business structure may not be as complex as a large airline so having a simple, straightforward inventory control and booking structure would be best. The nested structure provides the best opportunity for an airline to maximize their revenue opportunities for each leg by having seats in all fare classes available at all times until capacity is met
