A new visible change was around when I was transiting Delhi over the long weekend just gone by. There was finally a structure near Gate 41 which outlined the new Vistara Lounge under development.
While there is no longer a committed schedule to when the Lounge will be launched (their initial announcements hinted at July/August 2015), currently, it may be a good idea if this one takes off the ground before the end of 2015. Since they will be able to operate a lounge within 12 months of their launch, that should give them a fillip.
Of course, I am keen to see what is inside this lounge. Club Vistara Gold members and Business Class passengers on Vistara will be offered access to this Lounge.
