Cons
While they say people over profit, the reality is that over the years Frontier has become one of the single most toxic work environments I've ever known personally or heard of. It is profit over people 100%. All the talk of being all in it together, making a difference in the world, and ensuring the best for their employees and suppliers is just that — a lot of talk. I was hopeful it could turn around but it's gotten worse. To the point where some activities there are questionable on HR legalities and many of the true salt-of-the-earth people who deeply believed in the original company mission have given up and left for other options. (This includes all their brands, not just the primary Frontier brand)
