エアロプレーンズ：アビエーション・アセンダントchacoさんのルール/インスト

AEROPLANES：CHARTERS 　Each player gets one charter tile of their color. Rather than placing an airport tile according to the standard rules in the base game, you may place your charter tile as a substitute into any destination that isn't a starting city. Place your charter tile on the board next to the destination, outside of the allotted spaces. A charter tile may only be placed by a destination that currently has an opponent's airport tile at that destination. Discard an airport tile from your available supply. You may never replace a charter tile. Treat the charter tile as if it were a standard airport tile for passenger movement and direct connections. You may not score any victory points from your charter tile.
