(I posted in a different thread about the recently proposed and again negated Spirit/Frontier tie up. But this seems an appropriate place to plant food for thought...)

Maybe JetBlue and Frontier should be the ones getting together!

Both are moving to premium seeats and facing greater legacy competition against any lower cost model. Both are in less of a crisis mode than Spirit financially, but both NEED the cost synergies. Dump their expensive NY/Denver HQs and go to FLL or MCO...

Better with F9 to give more feed for the XLRs routes from BOS/JFK. Just a 2 fleet type A220/A320 operation. A220s fit in many of the smaller F9 markets too. B6/F9 together would compete more effectively against the legacies in places like BOS/LAX/RDU/DEN/PHX/NYC/MCO/TPA/LAS and more. Bag fees, seat assignments, and such in pricing model will work itself out...

(I say this aware of some individuals' future speculated Alaska/JetBlue tie up in miind, which I believe to be without merit. That merger would be too vast and too complex...Pacific rim to eurpoe spread and 5 fleet types (A220/A320/B737/A330/B787) is just too much complexity for a newly merged company...to say nothing of merging more workgroups (and labor agreements) into the fold without a not-yet-finalized (Alaska/Hawaii) merger.)
