2+ 1 year old, tentative plan - arrive terminal 1 on jal at 1145. Will have checked bags. Need to fly out term 2 on hainan airlines at 1315. No status. Two different tickets In essence 90 min, Hainan has 60 min check in baggage requirement. What do people think? I'm assuming I'll have to clear customs/Immigrations right? Too risky?
