So the family and I are arriving HKG from FRA on LH next week (16h00-ish arrival). We have an onward flight to HAN with HK Express the next morning 07h45 (UO550). Separate tickets.

My plan was to enter HK, pick up our luggage, and then go up to departures where we can self-checkin and self-drop the luggage for the UO flight. Then go to the Sheraton Tung Chung with only our carry-ons. Next morning go back to the airport, clear security and immigration, and be on our way.

amidoingitright?

Considering this will be a Friday a.m. flight to HAN, how early should we be back at the airport?
