The Airport Express Line provides connectivity from New Delhi Railway Station to Indira Gandhi Airport (T3) terminating at Dwarka Sector 21. Passengers arriving at or boarding flights from Terminal-1 can also avail this service from Aerocity Station.
Passengers can travel on the line at a discounted fare of Rs 30 per trip on Tuesday, Reliance Infra said in a statement. The Airport Express Line would run from 5.30 a.m. to 11.30 p.m. daily at a frequency of 15 minutes, the company added.
Baggage check-in for both national and international travel would start shortly, the company said.
In addition to single journey tokens, the Airport Line has introduced new products in the form of Return Journey Tokens and Sunday/Holiday discount tokens while retaining the Monthly passes for regular commuters.
The Delhi Airport Metro line started its commercial operation in February 2011, but services had to be suspended in July 2012 because of defects in civil structures.
"These defects have since been rectified by DMRC and the line was offered for re-inspection to the Commissioner Metro Rail Safety in December 2012...a formal clearance for commercial operation was received on January 18, 2013," Reliance Infra said in a statement.
Shares in Reliance Infrastructure closed 4 per cent higher at Rs 548.50 on the National Stock Exchange. The stock was the top gainer on the 50-share Nifty benchmark.
