Picked up several passengers here from arriving flights. The process doesn't get much easier which is why I love this airport.
1. arrive at the cellphone lot, just south of the airport, a large gravel area for parking and waiting. There are no rules or patterns to follow here, since there are no pavement markers people often form a semi-circle waiting on flights. Odds are most of the people in the cell lot are all waiting on the same flight anyway.
2. if weather allows simply open your car window a little and listen. There are not too many flights at this airport, so a commercial jet aircraft landing a half mile away is totally obvious just by listening.
3. wait ten-fifteen minutes then drive up to the front door and watch for your arrival to walk out the door with their luggage, or...
4. wait for them to text you that they are waiting by the door.
Doesn't get much simpler than that!
