I'm arriving to DEL in LH F and transferring to UK in J with an eight hour layover, I also hold an AmEx Platinum. Any thoughts on how to spend the layover? I'm guessing clear customs ASAP and bounce around the various lounges (AmEx, Plaza) but it seems like I may not be allowed within the Domestic terminal until T-4 for my flight? I'm open to a transit hotel too but I don't think my layover is long enough to warrant doing so. Would I also need to wait to drop my bag with UK as well?
