How does Spirit reject JetBlue’s more superior offer? I thought the fiduciary responsibility meant to go with the higher $$$ offer for investors because both Frontier and JetBlue were qualified buyers?

Because I recall jetBlue offering $55/share for Virgin and Alaska offering $57/share, and Virgin took the Alaska offer. Despite the fact VX/B6 made way more sense (similar business model, fleet, easier integration, etc).

With Sprontier moving forward, this definitely leaves the door open for an Alaska/JetBlue combination someday. JetBlue buying Spirit would have closed that door.
