Just wondering if anyone knew the earliest time that you can check in and drop off your bags at JFK airport for a Qantas flight (QF108, JFK to Sydney via LAX). My friend has an earlier QF flight that day (we accidentally booked ourselves on different flights!!), and ideally we'd go to the airport together, but it is a lot earlier than my flight, and I don't want to have to hang around and wait for my flight to open.
