Government today said there is no proposal before the government to regulate economy class air fares for domestic routes and carriers are free to fix ticket prices. <br/><br/>In a written reply in the Lok Sabha, minister of state for civil aviation, Mahesh Sharma said air fares are not controlled by the government.Mr Sharma said airlines are free to fix the ticket rates after taking into consideration various factors, including cost of operation and characteristics of service.<br/><br/>A Tariff Monitoring Unit has been set up at the Directorate General of Civil Aviation (DGCA) to monitor air fares on certain routes on a random basis. This is to ensure airlines do not charge fares outside the range declared by them.<br/><br/>In a report tabled in Parliament on Tuesday, the Department-Related Parliamentary Standing Committee on Transport, Tourism and Culture had suggested a cap on maximum air fares.
