What the report about the cancelled flights doesn't mention are all of the flights that were flown by other carriers as subservice. For those who don't understand the way it works here:

Let's say you have to bake a cake. The recipe calls for 3 eggs. Let's say you go to the store and all they sell are 6 eggs in a small carton. A reasonable person would buy the carton because they know that they'll at least have 3 eggs left over just in case one falls on the floor or one is bad. Allegiant would buy the carton from a windowless van in the parking lot, sell 4 of the eggs off and attempt to make it work with 2.
