Not all of the flight schools that are open are full service. In many cases the flight school you may be looking at could just a retired pilot who has ventured on to a second career. In any case look at and ask to see the instructor's flight record as well as any credentials he or she may have.
Look into the various flight schools that are out there and then begin to comparison shop. Try to find out if there classes that are available and determine the costs. Also find out if they have crafts that are able to be used for instruction or if you will need to buy your own plane.
