Q400 ferry flight

And anyway generally any big airline player would rarely use small planes (unless they are really unrealistic).

Depends. Avianca has 10 or so Quest Kodiaks which seat 8-9 people, and Air Canada has Beech 1900s, which seat 19. Sure, a lot of airlines don't need small planes, but it isn't highly unrealistic. Haha sorry I'm going full realism mode here

Small planes do have a role in the airline industry, but not a big one, and generally, large airlines can afford to purchase / lease new ones rather than used ones.
