I need a bit of help with domestic to domestic transfers at BLR. I will be arriving on a separate ticket, GOA-BLR on Vistara, collecting my luggage, then re-entering Terminal 2 for a flight three hours later on Vistara, this time BLR-DEL. How do I physically get from luggage claim on Floor 1 of Terminal 2 to the check-in level? The detailed terminal map provided by BLR is unclear about this. Thanks.
