much describes the situation of an airline pilot.  

IF you are a helicopter pilot pay the state taxes of your residence and worry about the rest at tax time which will come down to the maximum of those state taxes due.

IF an itinerant pilot don't worry about it at all.  Pay your residence state taxes and forget the rest.  If challenged, which won't occur 99.99% of the time, then deal with it.  

State taxes are not something to worry about.  Let the statute of limitations do the job for you, and don't worry about undeclared income to any XYZ state.  Phissss hole in a snow storm

BTDT on all of it.

Get a CPA to do your taxes and breathe freely.
