Calais Marck Airport — Calais, France

Calais Marck Airport, coded CQF, sits just inland from the English Channel near the French port city of Calais, within sight of the white cliffs that mark the narrowest crossing to Britain. Historically the field has hosted small commercial ventures aimed at British travelers, including budget flights that came and went over the years, though today it functions mainly for general aviation, flight training, and light aircraft traffic. Its proximity to the Eurotunnel terminal and the busy cross-Channel ferry port places it in one of Europe's most transited coastal corridors, even though the airport itself stays quiet and small-scale.
