That website doesn't look very accurate. They estimate staffing based on aircraft instead of block hours. They also don't count our mandatory retirements. The unknown variable is attrition.

I've always found it odd that pilots look at pilots per aircraft when pilot staffing is really driven by block hours. APC says that Allegiant has 76 aircraft and 515 pilots, and Spirit has 65 aircraft and 1086 pilots. The difference is obviously that Spirit keeps the airplanes flying as much as possible because we have higher fixed costs and lower variable costs due to our new airplanes (when compared to Allegiant)
