My honest opinion is that I find going to GoJet morally reprehensible for some individuals, myself included. However, if you are outside of that box, I find that it has become a good option. There is certainly a quick upgrade time, and if the domiciles work well for you, even better. I have spoken personally with GoJet recruiters and captains who honestly are happy there, but I've also seen the other side of that coin.
If you go, understand that the quick upgrade may disappear at a whim, and then you will really be in a jam. Good luck, I hope for the best for what works for you.
