How do I book a flight and a hotel where the time zone is a day ahead or to be precise 16 hours ahead? Would the booking times be for here in the US or to wherever I am traveling? Im so confused on how it works, I don't want to incorrectly book hotel

All flights and hotel bookings are for local time at that destination, arrival time of a flight will be that destination local time.

The local time where you are going / visiting.

You book in the local time, not your time.

It's always for the local time you are going to.

You can call the hotel and agency you try to fly they know the schedule better.
