Arriving on UA 82 EWR-DEL around 2130hrs and connecting to UK 989 DEL-PNQ at 0310hrs. Plan is to go through transfer, use the Amex lounge until 2330, and then switch over to the PP lounge after that, which I'm assuming will be really empty as there are only 2 other flights I can find leaving T3 domestic after midnight and before my flight (Indigo to MAA and AirAsia to PNQ). Also have family coming in from MUC on LH after midnight, and plan to guest both of them into the PP lounge.

Any tips or suggestions for a better plan? I've never connected through DEL before - always used BOM, and in DEL gone into town.
