I'm not Mike, but let me try. Retirements at Big 5 have led to them calling applicants at a breakneck pace. Also Big 5 upgrades are pretty much instantaneous (less than 2 yrs) so why would anyone go anywhere else? Those that can't get the call today, will get it within the next couple years. Applicants are from the ULCCs and regionals. So if ULCC/regionals can't keep their pilots, let alone grow their flight crew staff - upgrades will evaporate.

That is really it. Big 5 - qualified ATPs get the call, lightning fast upgrades guaranteed by the mandatory retirements, highest pay rates & the siren call of WB pay rates. Big 5 are the place to be applying. If applying to the ULCC/regionals - it is absolutely a stepping stone to the Big 5. Even SWA/JB/Alaska are seeing attrition.

Most should be seeng this. If you are not, then enjoy flying for "not Big 5"
