When the oil prices goes up, the air ticket charges will go up. Once the air ticket charges goes up, the number of passengers taking the flights will reduce. This will reduce the profitability of the airline companies. Many will close down. Lot of people will switch to cheaper mode of transport. This in turn will force the airline companies to cancel the huge orders they have placed on air craft manufacturers without paying any penalties, because most of them have delayed the delivery dates of the orders placed on them. This in turn will will lead to reduction in pricing of the aircrafts …. there is no end to it…..
