You won't feel the scarcity of seats in the Airport Express Line. As you can see there are plenty of seats welcoming you. Go and grab your seat and enjoy the memorable journey of the magnificent and marvelous trip.
There is so much of space that can accommodate hundreds of passengers. Did you notice the surrounding areas of this metro line? It's so clean that anybody would vouch for; even the daily route of the Delhi Metro is not so clean. You may have noticed the wrappers thrown inside the metro, torned poly bags or the stinking puked thing… People will just close their nose and will move aside. Only some of them will complain about it. It seems that as if they are not concerned about the cleanliness drive.
