We do our own lobbying as well as what National does. On the national scale the interests generally are the same. When we lobby ourselves it is for things that are "generally" good for the DAL pilots. I say that because many feel that the time spent on the LGA slot swap did not show a concrete benefit. I saw a benefit but that was me. Many disagree.
As for National Pac. When Prater decided to be on the winning side of a bad issue (Age 65) a lot of ppl like myself pulled our ALPA-PAC money. I have since donated for specific causes.
