Capt. (Ret.) Reyné O’Shaughnessy

Airline Captain. Author. Speaker. Capacity Expert.

With her signature straight talk, Reyné names what many women have been experiencing—but have never been able to fully explain – being AT CAPACITY.

 

After more than three decades flying around the world, Reyné saw something she couldn’t ignore—what keeps airplanes safe is the very thing missing in the lives of many women. In aviation, safety depends on understanding limits, managing complexity, and protecting margin. Over time, she began to see a clear parallel: capable women were living without those same margins.

 

As a wife and mother of three, she understands this not just professionally, but personally. She has lived the weight of responsibility and the quiet accumulation that comes from holding a great deal for a very long time—and now leads a movement to change that.

 

Today, she translates the principles of aviation into clear, relatable insights—helping women reclaim space, clarity, and a more sustainable way to live and lead.

If You’re At Capacity,

If life has been feeling AT CAPACITY for a long time…

 

this is where you begin to understand why.

 

And where women start creating the space, the margins

 

That your body and mind was intended to have 

You’re ready for this.
