Scenic Flights is considering replacing the existing 2 hour flight with a more luxurious 1 hour flight costing $250 per passenger. Under the new proposal it is estimated that demand will increase to 190 scenic flights per year with each flight limited to 15 passengers. Flights will be conducted in the morning and afternoon over the week ends. Other costs to change from the original offer include: inflight refreshments up from $30 to $50 per passenger and the annual fixed costs to increase from $150,000 to $200,000. The two pilots and 2 flight attendants will each be paid $250 and $100 respectively reflecting the shorter duration of the flight compared to the original offer. Fuel costs also reduce to $450 per flight
