Digital Wings: How Frontier's AI Agent increases the NPS

Frontier Airlines recently made a bold move, turning off its telephone customer service in favor of exclusively handling interactions via chat with the support of an AI Agent. This strategic decision not only increased operational efficiency but also contributed to remarkable advancements in customer service. Achieving a 15% to 30% annual growth while maintaining cost efficiency, Frontier experienced a transformative shift in passenger interactions with the implementation of Cognigy’s AI Agent for travel.

The Challenge


Frontier Airlines encountered multifaceted challenges amidst its impressive annual growth rates of 15% to 30%. Staffing contact centers proved difficult, especially with the intricate task of keeping agents' content amid expansion. Traditional phone lines, limited to one conversation per agent, posed constraints during peak times, exacerbating the strain on customer service operations.

The inherent limitations of traditional phone-based support became apparent during Frontier's peak periods and irregular operations. Managing contact center staffing was already a complex task, especially when experiencing growth. This challenge become even more intensified during these times. Agents, limited to handling one conversation at a time on the phone, struggled to manage the influx of customer inquiries efficiently.

The Solution


In search of a solution that could address the companies specific needs, Frontier Airlines implemented an AI Agent powered by Cognigy. The AI Agent efficiently validates reservations and provides quick links to make reservation changes seamlessly, addresses inquiries about baggage, processes refunds, and hands over to live agents on chat when necessary.

The introduction of an AI chat agent became the catalyst for overcoming Frontier's challenges. The AI Agent's capacity to engage in hundreds or even thousands of conversations simultaneously revolutionized customer service operations. This not only addressed the difficulties in staffing and agent satisfaction but also provided an instantaneous and efficient solution to customer queries. This also aligned perfectly with Frontier's commitment to delivering exceptional service amid growth and operational fluctuations.

"With the AI Agent managing customer inquiries, we saw a rise in our NPS score and a reduction in our AHT compared to providing support through our phone channel. In fact, our average handling time is currently at its historical low, at least in the last five to six years."
