Yes, it would be nice if all the airlines had the financial performance of Allegiant, but in this case I’m talking about how the carrier formats its income statment.
Take a look at the revenues section:
And compare that, for example, to AirTran:
Allegiant records ancillary revenue as its own independent section, while other carriers just put that into the “other” category, and we’re left guessing exactly how much of that “other” revenue is from fee intiatives.
It would just make the lives of insignificant bloggers like myself easier if other carriers did what Allegiant did. 
That 1.7 percent loss on scheduled service revenue really drives in the point of how hard Allegiant works to keep their planes full. Allegiant will never second-think removing a city from their network if it’s not making money; even if LF are high, they expect a certain amount of Ancillary Rev.
