For purposes of the September 11 Security Fee, a domestic => international connection will incur an additional $5.60 fee if the connection time exceeds
12 hours -- not 4 hours, and not 24 hours.
Of course, if the connecting QR flight departs from an airport
outside of the U.S., then no second September 11 fee would be due.
