About Us

A boutique approach. A global reach.

Our Promise: Discreet. Bold. Always bespoke.

LACOURSI AIR was built on a simple conviction: the most consequential aviation decisions deserve counsel that is calm, precise, and free of agenda. We advise private clients, corporations, and institutions on aircraft transactions, fleet strategy, and aviation infrastructure — from a single acquisition to a sovereign mandate. Our bench brings decades of combined aviation experience across transactions, maintenance, operations, engineering, finance and advisory.

Our Story

LACOURSI AIR was founded by RoseMarie LaCoursiere after the aviation division of a leading global brokerage closed, revealing a clear opportunity for a more discreet and relationship-led model. What began as a relationship-led aircraft advisory platform has expanded into strategic aviation development, ecosystem development and cross-border opportunity creation.

With a background in luxury real estate and a long-standing appreciation for aviation, RoseMarie built LACOURSI AIR to serve clients who prefer a more tailored experience — one grounded in trust, thoughtful guidance, and strategic alignment.

Rather than operate as a high-volume brokerage, LACOURSI AIR is intentionally focused on a more refined path: fewer, better relationships, carefully handled opportunities, and a standard of service shaped by discretion and judgment.

What Sets Us Apart

LACOURSI AIR is not built on noise, scale, or volume. It is built on access, trust, and the ability to move thoughtfully within a highly relationship-driven market.

That same relationship-led approach now extends to aviation development, strategic partnerships, infrastructure and international mandates — identifying opportunities, opening the right relationships and helping move them toward execution.

We do not wait for opportunities to arrive fully formed. We identify them, map the ecosystem around them, assemble the relevant players and help move them toward execution.
