Final answer:
The key differences between services on short/medium and long haul flights stem from flight duration, with long haul flights offering more amenities and comfort due to the extended hours spent in the air.
Step-by-step explanation:
The question is asking about the differences in services provided by airlines on short/medium and long haul flights. Due to the impacts of deregulation, there has been a significant reduction in airfares, increased efficiency, and the development of hub-and-spoke systems that increased connectivity between cities. These changes have benefited consumers with lower fares and more service options, leading to a substantial increase in air travel and consequently doubling airline industry employment. Notably, these improvements have come alongside enhancements in safety due to government oversight.
On short/medium haul flights, services are typically more limited due to the shorter duration of the journey. These flights may offer basic in-flight amenities and are more likely to use smaller aircraft. In contrast, long haul flights often provide a wider range of services to enhance passenger comfort for the extended travel time, including meals, in-flight entertainment, and additional legroom.
