But, I learnt something this last week. The reason commercial hot air balloon flights are so expensive is because of the costs involved. If you have a friend with one, he may only ask you to pay for the gas. The commercial operators need to make a profit, so they factor in the cost of the pilot's time, the pilot's certification costs, the balloon canopy and basket certification costs and the cost of the gas. On top of that, the balloon canopy has a limited lifespan. If flown "cool", the canopy will be flown at around 90degC, while, if flown "hot", the canopy may be at 120-130degC. This deteriorates the fabric much faster and hence the shorter flight hours. If flown more gently, i.e. slower ascents, then the lifespan of the canopy can be extended. But, if pushed hard, the envelope will deteriorate faster.
If flown only during cooler weather, and with a light load, the canopy may last around 300-400 hours. But, if flown heavy, during warmer weather, and with fast ascents, the canopy has a lifespan of about 200 hours.
So, to break even, the cost is divided into the 200 hours flight time and divided by the number of passengers along with a factor based upon average numbers booked per flight. Hence the high cost per person, per flight.
