There is also a dedicated pre check-in waiting area for Business/First passengers in case if you reach early i.e. before the check-in counters have opened. This is on the extreme left & right of the airport.

Plus if you are on the LX flight to Zurich or LH flight to MUC, then you are among the first few business/first passengers going through the dedicated security/immigration counters. It is only after midnight when the Mumbai airspace starts getting busy with international flights.

BTW, since the lounge is new, you are escorted by someone to the lounge. Feels like you are getting that royal treatment.
