I'm flying SFO - HKG - ICN on same ticket; first flight is in CX F, second is in CX J. Arrive in HKG at 6AM, then departing 19 hours later at 1:05am. I recognize this isn't technically "same calendar day". Am I likely to face any push back on being granted lounge access at 6am for a 1:05am departure or entering the departures area 19 hours before my flight?

I don't intend to spend 19 hours in the lounges, but would like to nap, eat, and freshen up before heading into the city for a few hours and then going back to the airport lounges to relax. I recognize doing so would require asking to be escorted from departures area to immigration. If I'm already pushing my luck, I might need to reconsider.

Thanks!
