Flight information can be found by searching flightaware.com for recent flights between airport pairs. It would take some work as the results are just a recent snapshot of flights. You can search here: Flight Finder - FlightAware As an example, here are are the search results from a PANC - PANI search: Flight Finder ✈ Anchorage Intl (PANC) - Aniak (PANI) - FlightAware As you can see there is an Evert’s MD-82 that flew that route. Another flightaware search technique would be to search by aircraft type (DC6) or by Everts call sign “VTS”.
