Seabury Group

John Luth, as Chairman and CEO, retains ultimate authority over the firm's strategic direction and investment committee decisions. Day-to-day advisory and restructuring mandates are led by senior managing directors within the corporate advisory group, each typically possessing deep aviation finance or operational backgrounds.

The firm leverages a multi-decade repository of airline operational and financial benchmarking data, originally built through its consulting practice. This proprietary dataset, combined with Luth's long-standing relationships with airline boards, creditors' committees, and aviation lessors, means mandates often come inbound before a formal RFP process begins.

Seabury is an employee-owned investment bank and advisory partnership, not a family office. Its holding structure, Seabury Capital Group, controls registered broker-dealer, consulting, and asset management subsidiaries, all operating under the broader Seabury brand with aviation as the unifying vertical.

Through Seabury Asset Management, the firm deploys capital into aviation-related structured debt and equity opportunities — including aircraft leasing platforms and spare engine portfolios — often on a co-investment basis with institutional partners, though the size of its proprietary capital pool is not publicly disclosed.

The firm does not pursue generalist M&A or restructuring outside aviation, aerospace, and freight transportation. It has historically declined mandates in retail, oil and gas, and other distressed sectors where it cannot leverage its proprietary operational data.
