"We made many strides in 2023, including the start of our transition to a more reliable, simplified network strategy designed to benefit our customers and boost our efforts to further mitigate our environmental footprint," said Frontier Airlines CEO Barry Biffle. "We also took initial steps toward adopting the use of sustainable aviation fuel and achieved a major milestone in charitable giving. We are excited to fully detail our 2023 achievements throughout this report."

Environmental Sustainability Highlights:

• Began implementation of an out-and-back network design, in which aircraft and crew return nightly to their home base on about 80 percent of scheduled flights to create a more efficient operation that also supports relative lower greenhouse gas emissions
• Continued to operate the most fuel-efficient fleet of all major U.S. carriers when measured by ASMs (available seat miles) per fuel gallon consumed, generating over 104 ASMs per gallon as of December 2023 and saving approximately 160 million gallons of fuel as compared to the industry average*
• Operated a fleet with an average age of 4.3 years as of December 2023, among the youngest fleets in North America
• Encouraged operating practices among our pilot group to conserve fuel such as reverse thrust, single-engine taxi, and no Auxiliary Power Unit techniques
• Employed measures to reduce aircraft weight such as a la carte food and beverage service resulting in less packaging, plus lighter weight aircraft seats, to reduce fuel consumption
• Elimination of plastic stirrers and use of biodegradable beverage cups on board
• Paperless cockpits and electronic manuals to eliminate paper waste
• Use of aircraft engines that feature a reduced noise footprint
• Introduction of additional aircraft featuring tails that highlight threatened and endangered species from throughout North America to raise awareness and underscore their plight

Commitment to Customers and Team Members:

• Continued commitment to high safety standards in every area of our operation
• Safety-related data sharing through industry-wide initiatives to support best safety practices and learnings
• Ensuring high standards and best practices in data security and customer privacy
• Compensation and benefit offerings designed to support the financial, mental, and physical well-being of employees and their families
• Extensive team member training and professional development opportunities
• A commitment to further bolstering diversity, equity and inclusion among our workforce
• Partnering with aviation industry employee advocacy groups
• Establishment of business resource groups supporting Team Frontier diversity
• Supporting crew members' choice to participate in unions and collective bargaining

Community Engagement

• Giving back to our communities through volunteerism, in-kind donations and fundraising
• Raised $395,000 in 2023 for Folds of Honor (bringing the collective total raised for the organization by Frontier to nearly $1 million), a non-profit that provides scholarships to families of service men and women who have fallen or been left with a disability while in the line of duty

"Every member of Team Frontier deserves credit for the ESG accomplishments highlighted throughout this report, and I am beyond grateful to lead this amazing team of dedicated, caring professionals. I appreciate the trust our customers, valued shareholders, and team members have placed in our organization as we embark on years of continued sustainable and responsible growth," said Biffle.
