To add - for anybody determined to walk from AirTrain to the A train to avoid paying the $5 fee, this is the shortest walking route: https://goo.gl/maps/dQHSpE9y8PD2
It's a mile. I did it once, just to say I did it, without luggage. It wasn't pleasant, and I wouldn't want to do it with luggage, or at all in the heat or rain or snow.
If you want to avoid paying $5 and you have a MetroCard with at least $2.75 on it, one of the buses (Q10 Limited or B15 from Lefferts Blvd, or Q3, Q10 Limited/local, or B15 from Terminal 5) is almost certainly a better bet.
