If they can make it work for them, then it IS a good deal for them, despite your ALPA-based thought process. I don't know why that's so hard for you to comprehend. That's based on the company's manning model and business practices.
In order to replace our system with a "real process that other legacy airlines have," where one could "straight drop trips" regularly, Southwest would need a much higher reserve percentage than we do (we have something like 8-9% reserves), and hence a much overall greater pilot-per-plane ratio than we have. While I realize that's ALPA's gameplan--more pilots equals more dues-payers and money to Herndon--it's not the way we like it here. At Southwest, there's no maximum amount you can work, other than dictated by FARs. Other than months like February when the schedule's light, there's essentially no limit to how much you can pick up.....if you want to. The schedulers even say that they count on a certain percentage of pilots being greedy, in order to cover everything.
And I'm not stroking anything. There are plusses and minuses to every system that's out there. I work the amount I want to work. Other pilots here work much more than me, and are compensated as such. That's a flexibility that ALPA carriers don't offer.
