The article states that they plan to use a A321NeoLR to serve LGW and the aircraft will be able to fly for between 8 to 9 hours and that the new route will require a stop en route.
I wonder if if they are planning to use airports already served by indigo in the Middle East for the en route stop. For instance LGW-DXB-DEL. If they did this how easy would it be for Indigo to be granted traffic rights for the LGW-DXB portion of the journey?
