And who are the main investors for Indigo Frontier Holdings Company, LLC?


Indigo Frontier Holdings Company, LLC is a private investment vehicle affiliated with Indigo Partners LLC, a private equity firm focused on aviation investments. It served as the holding entity for a major stake in Frontier Group Holdings Inc. until a pro-rata distribution of shares to its members in April 2024. As a private entity, full details on all limited partners or investors are not publicly disclosed, but based on regulatory filings, press releases, and reports, the primary control and key investors are tied to the following individuals and entities:

• William A. Franke: The founder and managing partner of Indigo Partners LLC. He controls Indigo Frontier Holdings through Indigo Denver Management Company, LLC, of which he is the sole member and managing member. Franke retained a significant direct stake in Frontier following the 2024 distribution.

• George R. Roberts: Co-founder of the private equity firm KKR & Co. Inc. He is a prominent limited partner/investor in Indigo Partners’ funds, including those related to Frontier. Roberts also continued to hold a meaningful stake in Frontier post-distribution.

• David Bonderman (via Wildcat Capital Management, LLC): Bonderman, co-founder of TPG Inc., invested through his family office, Wildcat Capital Management. This entity was a key investor in the Frontier holdings and retained a substantial position after the distribution. Bonderman passed away in December 2024, but his estate or Wildcat may continue to hold interests.
