Sorry, 6E is the airline code for Indigo. You can ask in indigo check in or any indigo staff. There are a lot of staff near the check in and baggage drop area. They’ll be more tha happy to assist. From experience, if there is lounge access for your ticket you’ll get an invitation card to the 080 or any lounge at domestic.
Another thing is you can check your
boarding pass. Sometimes lounge access is printed on the boarding pass.
