What safety features are found in the cabin of Frontier Aircraft?

The correct choice highlights critical safety features that are essential for passenger safety in the cabin of Frontier Aircraft. Emergency exits are strategically positioned to allow for a quick evacuation in case of an emergency. Oxygen masks are available to provide supplemental oxygen to passengers if the cabin pressure drops, ensuring they can breathe until safe conditions are restored. Life vests are also present, particularly on flights over water, providing flotation assistance should an emergency landing become necessary.

These features are designed to protect passengers and crew, ensuring their safety in various emergency situations. While other options include valuable amenities and equipment that contribute positively to the flying experience, they do not directly address immediate safety needs in the way that emergency exits, oxygen masks, and life vests do.
