Okay, I'll bite.
No ill will at all towards Frontier, but I don't see any way Frontier can survive long term. With the number of order slots with Frontier's name on them, a relatively cheap labor force and a brand name with a following, Frontier is ripe for the taking. It won't be long before Frontier is merged, and my guess is with JetBlue. This would give JetBlue a lot more exposure to the central part of the United States, a ready infusion of much needed Airbus orders and a pilot group they can easily fold into JetBlue.
I wouldn't anticipate a lot of complaints from regulators seeing as how JetBlue isn't one of the top four airlines, Frontier doesn't hold a dominant position in any market and it's currently a privately held company.
Just my crystal ball guess, no expertise or inside knowledge, just a guess.
We're not done with the mergers.
