What would happen if you just took a commercial plane and drive it straight up into the atmosphere trying to reach space?

If you actually tried to fly it straight up, it would stall.

If you tried to fly at the maximum rate of ascent, eventually the air would get too ~~think~~ thin for the engines to work, or for the angle of attack on the wings to have much of an effect, so you'd be effectively limited to a certain altitude (what that is depends on the aircraft)
