Hey, and as far as imputed income goes, it depends on the base and your travel situation. ANC in 2012 $6800, ANC/LAX 2013 - $6400, 2014 LAX/PAE - $4500, 2015 PAE - $0. It just depends on your travel situation and base, but for me the trips always seemed to start and end in ANC and it's expensive to get there. LAX, it's cheap to fly in but expensive to be on reserve there. And PAE - my situation afforded me the opportunity to not get jabbed with travel expenses. Regardless, imputed is always hit and miss AND you will pay real taxes on this as ordinary income.
That said, gateway is a good deal that would keep me here... for a little while longer as there must be movement soon on a new contract. It also offers peace of mind over jumpseating and getting a condo (I'm to old and set in my ways to live like a college student in a crashpad). Without it, I would quickly move on.
All In!
