During a turnaround, the priority is to secure the aircraft for the next phase by making sure doors are properly closed and latched, and that no service lines or ground equipment are snagged in or around the door. This ensures the door seals are engaged so the cabin environment and any pressure considerations remain safe, prevents accidental opening during taxi or pushback, and keeps ground crew protected from moving doors or entangled lines. Other options don’t fit because removing doors isn’t part of routine operations and would compromise safety; leaving doors open to ventilate the cabin is a major hazard during ground operations; and focusing only on cleaning the door seals neglects the essential steps of securing the door and clearing the surrounding area, which are required before boarding and ground handling continue.
