Anything is possible in this industry.

Don't underestimate Indigo partners.
Indigo owns Frontier.
They were also a major investor in Tiger Airways.
They currently own a piece of Volaris.
They still own major share of Wizz Air.
Previously owned 49% of Russian LCC Avianova.
In the last two years they tried to purchase the majority interest of LOT from the Polish government.
In February of this year started a new upstart ULCC in Chile. Yup started a whole new airline complete with more animals on the tail.

In November of last year Indigo committed to partnering up with the Canadian airline Enerjet. Indigo will help transform them into a ULCC with up to a 25%(limited by Canadian law) stake of the company.

Combine the experience above and a CEO that already thinks there will be a consolidation amongst low cost carriers in the US and anything is possible.
