This photograph taken in Les Abymes, on the French Caribbean island of Guadeloupe on April 30, 2026, shows a closed office of French regional airline Air Antilles at Maryse Conde airport's regional terminal. The regional airline, which had been serving the French Caribbean islands (Saint Barthélemy, Saint Martin, Guadeloupe and Martinique) since 2002, had been facing a series of setbacks for several years. On April 27, 2026, the Commercial Court of Pointe-à-Pitre (Guadeloupe) placed Air Antilles into administration, due to the lack of a takeover bid deemed credible.
