I have a friend that is in the same predicament. They have offers at both JetBlue and Frontier. They live in-base with Frontier (ORD) but it's their smallest base and it has been stagnant for years. They may grow the base with some of their new plane orders, but that also requires adding gates which may or may not happen.

I'm pushing him towards JetBlue because it seems like a better company overall. Frontier is a riskier move, though the payoff may be higher. I just think Franke and Co. are a big risk to Frontier, and frankly, they're not innovating. To assume they can just pull of a Spirit 2.0 isn't that simple.
