I usually fly out at 6 am. Usually arrive between 330-4 am. They run 24 hours a day. Never had an issue getting one at that time. Little more gap in between a they run less shuttles but still not a huge wait if you need to wait for one.
The shuttles run 24 hours a day every 8-10 mins except between 1am & 5am they run every 25 mins
I caught one at 4:30 am
Not sure. Think it's 24hrs/day. Maybe less frequent at that time maybe
