Reserve is great. Whenever I don't want to fly, or want certain holidays off that I can't hold on a regular line, I bid reserve. I flew 12 hours in November and about 15 in December working about 4 days each month.
When I was hired (over three years ago) you were assigned to your initial aircraft based on whatever the "needs of the company" were at the time. This was in clear violation of our contract, which states that you will bid on aircraft based on your seniority within your new hire class. When I pointed this out to the B#$&h that was in charge of newhire training, she told me that I had a "bad attitude". When I pointed it out to an ALPA Rep, they told me that they were giving the company a pass on aircraft assignments because (at the time) they were having problems finding people that could or would upgrade to Captain on the E-120. Those of us with the most experience were assigned to the E-120 and told to expect to upgrade within one month. Naturally, that didn't happen. What is the moral of this story, ASA can do whatever they want with regards to newhire aircraft assignment.
