Pros
Being a non-profit, AOPA's strength is that it is mission-focused and makes decisions and adapts to a changing landscape in order to do what's right for aviation as a whole, not just a set of stakeholders. That means that change is inevitable, as the problems facing general aviation are incredibly complex and can't be solved with one solution. Creativity is welcomed, as is a take-charge mentality that many companies shy away from in their staff. The benefits are great, the flying perks are outstanding, and the culture is work-life balance focused. AOPA isn't perfect, but it's a breath of fresh air compared to companies that focus on leaning expenses, putting employee satisfaction on the bottom of the priority list. The CEO, Mark Baker, is also very forward-thinking and welcomes new ideas to old problems. The difference can be seen with the initiatives and changes that have gained momentum under his leadership.
Cons
As with any company, there are people at AOPA who do not want to change, who see new people as a threat, and who get complacent in their high-ranking titles, earned by tenure. No doubt negative reviews hang on frustrations caused by those people, justifiably. But that being said, the challenging few are overshadowed by genuinely good people with great ideas. Under Baker's leadership, the organization is making some real headway and heading in the right direction. Pay is also pretty low for newcomers, especially in comparison with the tenured employees who have had steady pay increases over 10+ years, but the great benefits and free flying money help make up for the con.
