Delavan (C59) ⇄ Chicago/Prospect Heights/Wheeling (PWK)

3 occurrences on flights between Lake Lawn Airport and Chicago Executive Airport, as the departure and destination were reported for the first aircraft involved.

Reported airports are matched to an airport only when the match is unambiguous, so flights whose airports were recorded loosely are not counted here. Records hidden on the map by default (minor, with little written about them) are included.
