I've been struggling to schedule my flight lessons. My current instructor tends to be available later hours, and the planes I've been training in book up especially fast during that time of day. I sometimes have weeks between lessons because of the scheduling problems.
I realize I could just switch completely to another instructor, but I basically like working with the instructor I have. On the other hand, it occurs to me I might stand to gain from getting some diversity of instruction style.
In some traditions, teacher loyalty is considered important. I don't get the sense that it's super important in aviation (especially since so many CFIs are just building time to ATP). But how unusual would it be for a student to regularly bounce between two instructors to make scheduling easy? Would such a thing be frowned on?
