Dallas-based RAA has announced that it is merging with Seattle-based Resource Navigation Partners.

RAA is a registered investment advisor that primarily serves airline employees and specializes in 401(k) management, financial planning, investment management, estate planning, benefits planning and insurance guidance.

Resource Navigation Partners, also known as RNAV, engages in comprehensive financial planning. Seattle, where RNAV is headquartered, is also the headquarters for Alaska Airlines and is a growing base for Delta Air Lines.

RNAV’s president, Fred Kneib, will stay on at the combined firm, said John Bentley, president and CEO of RAA. Kneib spent 30 years as a Delta Air Lines captain and previously served as the representative of the Air Line Pilots Association in the areas of retirement and insurance.

“RAA is excited to add the resources and expertise of Resource Navigation Partners to RAA,” said Bentley, in a released comment. “Together we will continue to serve and act as a fiduciary partner to active and retired airline employees and their families.”

Additional terms of the deal were not disclosed.

The merged firm, which will move forward as RAA, will retain a presence on the West coast and oversee approximately $2.5 billion in AUM.
