I saw this browsing while through some airline articles. It's about Frontier thinking about joining an Alliance to stay competitive.

Personally, I think it would be awesome if they joined star alliance. Republic is already an franchise carrier for US and even has some jets painted in Star Alliance livery. About 59% of their franchise operations are for *A carriers, so this would likely make the most sense IMHO. I'd love to earn UA EQM's/RDM's while enjoying a warm chocolate chip cookie.
