For a trip in February, I'll be traveling on the following outbound flights:

AA175 DFW-NRT (arrives NRT 2:30PM)
AA5838 NRT-KUL (departs NRT 1:40PM the next day)

Since DFW-NRT AA175 arrives too late to catch the one flight a day to KUL (NRT-KUL AA5838 operated by JL as JL723) on the same day, is it standard policy for AA to pay for the hotel? Or am I on my own and need to make my own reservations?

If anyone has any experience with this sort of overnight layover due to flight schedules, I'd appreciate any information. Thanks!
