With all due respect and no offence to you Sandeep, this is what I think of airlines
1). Phenomenal capital costs required to expand - you are operating a mumbai to delhi flight segment. You want to add a delhi to bangalore sector? Great!!! Investment is $200 million for a boeing 737 only! Make this investment and then cross your fingers and pray to God that no-one else will crowd the sector and you can reach the 65-70% capacity utilisation to first break even.
2). Volatile fuel costs with no ability to pass on increases in cost.
3). Severe competition intensity - every day there is a new company offering tickets at Rs. 1.
4). Huge burden of taxes on jet fuel - taxes cost more than the fuel itself
5). Commodity nature of business - people pick the lowest cost airline that gets them from point A to B. Period. Thats the only reason why anyone would ever travel air-india! If there was no cost saving incentive, who would want to subject themselves to that kind of torture?!
6). Huge amounts of regulation - its almost ironic because airlines lose the maximum amount of money because as soon as an airline raises prices and starts to make that tiny iota of a profit, govt/DGCA/CCI steps in to control prices
7). No pricing power and no bargaining power with suppliers (main cost which is interest, depreciation and fuel costs) - Can you imagine having any sort of upper hand when negotiating with a company like Boeing or Airbus? Its a duopoly, you have no choice, you have to buy from 1 or the other and they will charge you every last penny that you can afford to pay them!
8). Unscrupulous promoters are rampant in the industry. Although not discussed openly, it is a well known fact in the industry and there are a lot of side deals involved in purchasing air planes. True story!
I think it is quite possibly the worst industry in the history of mankind from the point of view of a minority shareholder (as a promoter you don’t end up doing as badly!). Unless I have an idea and the capital to start a new airline and have the conscious that allows me to siphon off money while making air plane purchases, I would rather withdraw money from my account, make a firecracker of it and watch it burn, rather than invest in an airline. Either way I am guaranteed to lose money. Here, atleast, I will be able to derive the enjoyment of watching fireworks.
