Spoiler for 42:

I would say the size doesn't matter much here. Just because he didn't show it when he awakened in the flashback doesn't mean he can't do it. Dragons as large if not larger than Alucard in other stories were easily able to fly. That being said, I also don't think he would be able to fly cuz that would be too inconvenient for Tsukune and co., but at the same time, I don't think such a thing would've been impossible.
