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 team averages 30 years in the industry. Our approach doesn't change based on the size of the deal. It changes based on what's actually at stake for you.

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.

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.

Through strategic alliances and established aviation relationships, we help clients navigate aircraft transactions with confidence while maintaining the level of privacy and personal attention these decisions deserve.

Our Team & Trusted Advisors

Our bench includes expertise in aircraft maintenance and technical inspection, aviation finance, FBO operations, aerospace engineering, and international advisory — assembled for transactions that require more than a listing service.
