JB has $600mill of unrestricted cash, so it could do the buying if F9 was something they need, but not the other way around. f9 does not have the cash ( almos 3bill market cap) and JB does not have enough asset to be the target of a leveraged buyout , so F9 buying JB totally on Unsecured debt would be a recipe for instant financial disaster.

I don't see jb buying f9 either, at the very least the similarities between PX and JB would be too mch for any investor to bear ( remeber the dissastrous buyout of original frontier by PX?) .

I would love to see JB and F9 join together and have a DEN base, but I don't see it.

how about UAL buying JB? similar 320's ,more East coast presence for UAL and 190's ( and eliminating a pesky LCC )
