There was absolutely no honosty in the wage comparisons from that memo, Skywest pilots know were they stand as does the rest of the industry. Assuming Skywest management believed in what their memo stated, they clearly are the ones that do not realize how their pay and benefits stand. I take great exception with your ideal of upgrade times. Even at Skywest upgrade times will vary greatly. Presently Skywest is and will continue to experience a noteable slow down in upgrade times. It is the nature of the business. Skywest has been able to passify their pilots with but as upgrades begin to normalize for the next few years and attrition halts due to the state of the majors their pilots face reality and that quite frankly is what you are seeing now.
Quite interesting from the memo, however, was the mention of the reduction in aircraft utilization due to reduced block times given by Delta. That is not a good thing for Skywest or its investors if it were to continue. Skywest has a large inventory of planes taged fro Delta and they can not afford to have them sitting on the ground.
Skywest has been a well run company and most likely will continue to be but first we will have to gauge how they weather this oncoming storm.
