Domestic Airlines tax increase

The prices of domestic airline's tax have again increased from the start of December. Now one has to pay Rs 2025 as tax for domestic flights. This rise in prices have been done gradually over a period of time. In 2006 one used to pay in 3 digits and by start of 2007 the prices went into 4 digits. If this continues one has to be ready to pay an increase in airline tax every 2-3 months. The best reasons either the government or the airlines justify for the increase is the surcharge on the fuel, construction of new airports or expansion of existing ones.
