hi-we're using a 2 hour 18 min layover since we're just coming down from Seattle. as long as your flight arrives on time it should be fine. if you want to be extra safe, do 3 hours. international flights leave out of L.A. at a different terminal, a bit of a hike but i've walked it easily before. it's just helpful to know that in advance! i don't know if they have shuttles...i just walked out of the arriving terminal and down the walkway to the international terminal.
