I went up to the flight deck of a PHX based crew and asked them about MAPD, saying I was a pilot looking to fly for the airlines. I was a little nervous asking them but they turned out to be really laid back. They gave me minutes worth of MAPD talk and the final concensus was "Don't do it". Most pilots are nice and are happy to help out new guys with career questions, just go up and introduce youself and ask them if they can help you out. Ask both regional and major pilots if you can, most have heard about MAPD and other academies.
