I assume there is access to the ventilation system through avionics. You don’t think the pilots could smuggle gas masks and knockout gas grenades on board? That is what I’d do if I was trying to hijack it.
So then whats the point of hijacking it? Its WAY easier to purchase a plane than to pull something like this off.

Night time flight = Most everyone asleep...
Disable the Cabin pressure sensor while at 30,000ft...
Slowly lower cabin pressure while wearing O2 masks in cockpit...
THEN release the knockout gas, most already O2 starved people would probably be killed by it...
Walk through and slowly slit the throats of those still alive but knocked out...
Shut off transponder(s)....
Lower altitude down to ground huggning levels and re-pressurize cabin...
No need to throw anyone over board....
All passengers and /or flight attendents dead...
Land plane in a airfiled somewhere....
Load plane up with EMP device (Iranian nuke)....
Re-register it and flight it to another airport somehwere that flies to USA....
Fly it over the USA, either east (between NYC and DC) or Over LA...
Detonate EMP device...
Digital 9/11.....
