I'm the most junior FO in my status. I sit ready reserve every month. I only live a few miles from the airport so I quickly got used to punching in at 2PM and heading home at 10PM. Only flew 20 hours last month.
I bring my Macbook Pro, headphones, a few DVDs and head to an empty section of the airport to relax for up to 8 hours. With the wifi connection I watch movies from Netflix. I bring my lunch so I don't spend much on airport food. It sucks, but at least I have a job. I have been doing ready reserve every month for the last 3 months....no end in sight.
