Spirit and Frontier Airlines on Monday announced a $6.6 billion merger, a combination of low-fare carriers that would create America’s fifth-largest airline.

The companies have yet to say what brand they’ll fly under or who would lead management of the new airline. The combined company would offer more than 1,000 daily flights to over 145 destinations.
