Jason can only summon one or two lightning bolts at a time, then what?
I would put it at two or three, actually. And it's not like lightning is the only power he has, he can use the winds to shove Nico around.
He could do a multitude of things. But for our sake, let's say he summons skeleton. Jason is outnumbered.
In The Blood of Olympus, Jason killed a hundred enemies by himself, similar to Percy's feat in The Son of Neptune. What do you mean?
Remember, Jason is also pretty drained considering he summoned lightning bolts as well.
In the later series he doesn't get as tired from summing lightning. There are multiple instances of this.
He can fly all he want but Nico would find a way to bring him to the ground.
How?
