Yes, Frontier Airlines charges $99 each way for pets traveling in the cabin. This charge applies to dogs and cats that meet the airline’s size and weight criteria and can travel in a soft-sided carrier. It’s vital to confirm availability since only a limited number of pets are allowed in the cabin per flight. Additionally, ensure that you have all necessary health documentation for your pet before traveling. For more information and to book your pet’s travel, please visit the Frontier Airlines website or contact their support team.
