How many of you that are against seniority have worked in a pt 135 or corporate flt dept? Lots of ass kissing, rule breaking to get upgrades, days off, the best trips, etc. Can you imagine the cronyism that could/would happen in a large operation such as AA, UAL, SWA or DAL? Depending who the DO or chief pilot is the upgrades would be based on squadrons, universities etc. We are Ll required to meet a set standard. Not all are able to make the upgrade. The seniority system is the only way to do it.
