Air commuters on important domestic routes very soon have to shell out more for flights to fund the government\u2019s regional connectivity scheme announced on Friday. Under this scheme, fares will be capped at Rs 2,500 for half the number of the seats in one-hour duration flights. Based on Consumer Price Index for Industrial Workers, the cap on fares will get reviewed time to time. The price will also vary according to the duration of flight under the Regional Connectivity Scheme (RCS), now named as 'UDAN'. However many existing airlines are not happy with the government's move to impose a 'very small' levy on departures on important routes in order to fund the scheme. They view this a reason for the pushing up of airfares and say that there are other ways to fund the scheme. The scheme has received accolades as well because of the plan to make flying to smaller cities affordable.
