I have a question regarding fleets. I remember seeing that as far as mechanics and techs go it's based on how many different types of aircraft you have. If I have some 767-200's, some 767-200ers, some 767-300's, and some 767-300er's is that one type, two types or four types? Same thing with A342 and A343, as well as all other types I guess, 737's etc...
