Plattsburgh maybe closer but again Syracuse is a much bigger airport and has many more commercial flights coming in and out. Plattsburgh is still a relatively new airport and hasn't really established itself yet. That may change over time, but for now there's limited airlines that fly in and out of it. If you want to go to Florida, Plattsburgh might be your best bet due to the non-stop flights they offer, but other than that, Syracuse is almost always the best choice.
